12L Double Head Extrusion Blow Molder: Boost Output for Farm Pesticide Small Drums
Apollo is a Wanplas factory based in Zhangjiagang near Shanghai, and for more than twenty years it has specialized in automatic extrusion blow molding machines built for hollow plastic Produkte ranging from a few hundred milliliters up to large industrial containers. With an 8,000 square meter production base, an annual manufacturing capacity of around one hundred machine sets, and over four thousand machines running across more than ninety countries, Apollo has become a reference point for producers who need reliable, high-output blow molding lines. This article focuses on a specific and increasingly demanded configuration: the 12L double head extrusion blow molder, and explains why it is an excellent match for farm pesticide small drums. We look at the technology, the material science, the productivity math, the selection logic, and the service backbone that Wanplas and Apollo provide together, so that a buyer can move from a vague capacity goal to a concrete, defensible machine specification.
What a Double Head Extrusion Blow Molder Actually Does
An extrusion blow molding machine forms a hollow part by first extruding a molten tube of plastic called a parison, then capturing that parison inside a split mold, and finally inflating it with compressed air so the material stretches and conforms to the cold mold cavity. The “double head” description refers to the die head assembly: instead of a single die head feeding one parison program, the machine carries two independent die heads that can each extrude a parison on its own schedule. In practice this lets the molder run two parisons side by side, either as two separate large parts or as twin multi-cavity nests, which roughly doubles the number of finished drums produced per machine cycle compared with a single-head equivalent. For a 12L farm pesticide drum, where the part is too large for the very high-cavity tooling used on small bottles yet too small to justify a slow single-cavity heavy machine, the double head layout hits a sweet spot of throughput and floor-space efficiency. The two heads are normally served by one plasticizing unit through a manifold, or by two parallel screws, so melt temperature and pressure stay consistent across both sides.
The core advantage of the double head design is not merely that it makes two parts at once, but that it decouples the parison program from a single timing constraint. Each die head has its own programmable wall-thickness profile, so the operator can tune the parison to place more material at the base and shoulder of the drum where stress concentrates, and less on the straight side wall where it is not needed. This saves resin, improves drop performance, and keeps the container weight within a tight band that matters for both cost and for meeting the stack-and-transport limits set by chemical logistics. In a pesticide packaging context the container must survive filling, capping, palletizing, truck vibration, and outdoor storage, so the ability to bias wall thickness precisely is a genuine quality lever rather than a cosmetic feature. Apollo configures its double head machines with servo-driven parison control and closed-loop melt pressure monitoring so that this tuning stays stable across an entire production run.
Why the 12L Format Fits Farm Pesticide Distribution
Farm pesticide small drums in the 10 to 15 liter range occupy a practical middle ground between the tiny 1L and 5L consumer packs and the bulky 200L returnable drums used by large agro-operators. A 12L drum is large enough to treat several hectares in a single fill, yet light enough for a single worker to handle, pour, and store without mechanical assistance. For distributors serving fragmented smallholder and mid-size farms, the 12L pack reduces the per-unit logistics cost compared with many small bottles, while still keeping the dose manageable at the point of use. Regulatory and safety logic also supports the format: hazardous liquid agrochemicals are typically shipped in sealed, leak-proof HDPE containers that carry UN performance-oriented packaging marks, and a 12L rigid drum with an integrated handle and a tamper-evident cap is far easier to seal, label, and trace than a flexible pouch. Producers who standardize on 12L therefore serve cooperatives, regional blenders, and contract fillers with a single versatile SKU that fits common pallet footprints and intermediate bulk handling.
Demand for this format is steady rather than seasonal in many markets, because crop protection Produkte are applied across multiple growing windows and are often pre-positioned before peak season. That steady, year-round pull is exactly what justifies investing in a dedicated high-output blow molder instead of outsourcing or running a slow general-purpose machine. When a filler needs, for example, two hundred thousand 12L drums per year, a single-head line may struggle to keep pace without excessive overtime, whereas a double head line absorbs the volume within a normal shift pattern. The capacity question is therefore not abstract: it directly shapes whether the packaging operation becomes a bottleneck that forces the filler to buy outside containers, or a controlled cost center that protects margin. The remainder of this article shows how to size that line and which Apollo configuration delivers it.
Material Selection for Pesticide Containers
For farm pesticide drums the dominant material is high-density polyethylene, commonly written as HDPE, because it combines chemical resistance, stiffness, low-temperature impact strength, and processability on extrusion blow molding lines at a favorable cost level. Pesticide formulations are frequently based on water, solvents, or emulsified active ingredients, and HDPE tolerates a broad range of these media without swelling, cracking, or leaching that would compromise the contents or the container. Medium-density and some linear-low-density grades are occasionally blended to tune flexibility, but the side wall of a 12L drum needs enough rigidity to stand upright when full and to resist creep under stacked pallet load, so a high-density base resin is the conservative choice. Polypropylene, written as PP, is an alternative where higher temperature resistance or a stiffer feel is desired, though it is generally less forgiving on impact at low temperature and slightly more demanding on process control. PVC is avoided for pesticide contact in most markets because of additive migration concerns and recycling friction.
The table below contrasts the three candidate resins on the properties that actually decide drum performance, so that a specification team can defend its choice with measurable criteria rather than habit. All values are typical ranges and should be confirmed against the resin supplier’s data sheet for the selected grade and any regional food-or-agriculture contact rules that may apply. Color masterbatch, UV stabilizer, and a slip or anti-block package are normally let-down at the hopper, and because the drum is not a food contact article the additive slate can be optimized for outdoor weathering and handling rather than taste or odor neutrality. Wall thickness distribution, set by the parison programmer, then does the rest of the work in converting a good resin into a drum that passes drop and stack tests.
| Material | Density g/cm3 | Impact at low T | Chemical resistance | EBM ease |
|---|---|---|---|---|
| HDPE | 0.94 to 0.97 | Good | Excellent | High |
| PP | 0.90 to 0.91 | Fair | Very good | Medium |
| PVC | 1.35 to 1.45 | Poor | Good | Low |
Beyond the base polymer, the filler must consider the cap and closure system, because a pesticide drum is only as safe as its seal. Most 12L drums use a threaded neck finished for a tamper-evident screw cap with an induction or wafer liner that resists the specific formulation, and the neck geometry must be held to a tight tolerance so the cap seats without cross-threading on the filling line. Apollo molds the neck as part of the blown article and can hold the finish to the customer’s cap standard, which removes a common source of leakage complaints. Additive packages for outdoor storage, including carbon black or a UV stabilizer masterbatch, extend the service life of the drum during yard or field staging, and these are dosed at the gravimetric feeder rather than mixed by hand to keep batch-to-batch variation low.
Core Machine Structure and Process Flow
A double head extrusion blow molder for 12L drums is built around a few subsystems that must work in tight coordination. The plasticizing unit receives HDPE regrind and virgin blend from a loader, melts and homogenizes it in the barrel through a screw with an L/D around twenty-four to one, and pushes the melt into the dual die heads. Each die head shapes the melt into a hollow parison whose cross-section and wall schedule are controlled by a moving mandrel or a servo pin. The clamping unit then closes the two-cavity or twin-part mold around the parisons, the blow pins pierce or seal the neck, and low-pressure plant air expands the parison to the cavity wall. After a short cooling window the mold opens and the take-out system transfers the finished drums to deflashing and leak testing. Throughout this loop the control system coordinates screw speed, head pressure, parison timing, mold close, blow, and eject so that the two heads stay in phase and the cycle time stays predictable. The whole sequence repeats continuously, and output is simply the number of cavities times the cycle rate times the operating hours.
Two details separate a drum-grade machine from a bottle-grade one. First, the clamping force must be sufficient to keep the parting line sealed against the internal blow pressure across a large 12L surface, so the clamp is sized in the range of roughly one hundred fifty to two hundred fifty kilonewtons rather than the lighter clamps used on small bottles. Second, the cooling must remove enough heat from a thick drum wall to let the part hold shape on ejection, which pushes the designer toward generous mold cooling circuits and sometimes a post-cooling jig for the neck. Apollo addresses both with a heavy platened clamp and a balanced water circuit, and the double head layout means the clamp is effectively shared across two parison streams, improving the utilization of that expensive structure. The result is a machine that feels over-built for the part, which is exactly what protects cycle time and tool life in a three-shift packaging environment.
Representative Specifications of a 12L Double Head Line
The table below lists representative specifications for a 12L-class double head extrusion blow molder in the Apollo ABLB series tradition. These figures describe a typical configuration for two-cavity or twin-nest tooling on 12L drums and should be treated as a starting specification to be confirmed against the exact mold and resin. Screw diameter, drive power, and clamping force scale with the total shot weight, and because a 12L drum in HDPE weighs on the order of six hundred to nine hundred grams, the plasticizing capacity is comfortably within a mid-size screw rather than a heavy-duty unit. The output figure assumes a balanced two-plus-two cavity tool and standard HDPE; actual bottles per hour will vary with wall thickness, cooling water temperature, and ambient conditions, but the order of magnitude is the planning anchor a buyer needs.
| Parameter | Typical value | Unit |
|---|---|---|
| Screw diameter | 80 to 90 | mm |
| L/D ratio | 24 | 1 |
| Clamping force | 150 to 250 | kN |
| Installed power | 70 to 90 | kW |
| Output | 90 to 140 | BPH |
| Max mold width | 600 to 800 | mm |
Energy use is an important planning input because a blow molding line runs the extruder continuously even while the mold is cooling, so the dominant load is the screw drive and the barrel heaters rather than the clamp. A double head machine spreads that fixed extrusion load across twice the output of a single head, which is one reason the configuration improves the energy cost per drum. Representative consumption lands in the low-to-medium band when measured as kilowatt-hours per hundred drums, and choosing a servo-hydraulic or fully electric clamp further trims the auxiliary load. Apollo offers both hydraulic and fully electric clamp options within the same machine family, and for a chemical drum line where the workplace may be humid or dusty, the hydraulic version is often preferred for robustness, while the fully electric version wins where the plant targets the lowest possible energy index and a clean hydraulic-free floor.
Apollo ABLB Series Double Head Machine
The Apollo ABLB series covers containers from 200 milliliters up to 20 liters and includes double head and multi-head configurations intended for mid-size industrial and agrochemical packaging. For the 12L pesticide drum, the relevant member is the ABLB-series double head machine in the 10 to 20 liter class, which accepts the large two-cavity mold needed for this part and pairs it with a parison control system that stores multiple wall schedules. A smaller sibling, the ABLB 55, serves the 2 to 3 liter range and shares the same control philosophy, so a producer who runs both small and mid-size packs can standardize operator training and spare parts across the family. Apollo positions the ABLB line as its workhorse for standard extrusion blow molding, and the double head variant is the natural choice when annual volume crosses the point where a single head line would need a second shift to keep up. The table below summarizes the ABLB double head 12L-class machine alongside its smaller relative for context.
| Model class | Container range | Heads | Output BPH | Power kW |
|---|---|---|---|---|
| ABLB 55 | 2 to 3 L | single or double | up to 320 | 40 to 55 |
| ABLB double head 12L class | 10 to 20 L | double | 90 to 140 | 70 to 90 |
| ABLB multi-head | 0.2 to 5 L | multi | up to 1200 | 45 to 75 |
What a buyer gets with the Apollo ABLB double head machine is not just a hardware list but a tuned process: the die heads are matched to the resin’s melt flow rate so the parison hangs without draw-down or surge, the clamp is sized for a stable parting line, and the control stores recipes so a product change from one drum spec to another is a recipe call rather than a re-engineering exercise. Apollo validates each machine with the customer’s actual mold and material before shipment, running a factory acceptance test that confirms cycle time, part weight, and leak performance against the agreed target. This de-risks the investment because the number quoted in the proposal is the number the line delivers on the floor, not a best-case laboratory figure. For a pesticide filler whose reputation depends on never shipping a leaking container, that validation step is as valuable as the steel itself.
Selecting the Right Configuration for Your Volume
Choosing between single head, double head, and multi-head is fundamentally a capacity and part-size decision. For 12L drums the part is too large for high-cavity multi-head tooling, so the realistic contest is single head versus double head, with the double head winning clearly above roughly one hundred thousand units per year. Below that threshold a single head ABLB machine may be the more economic buy because the mold is cheaper and the floor footprint is smaller, even if it runs longer hours. Above it, the double head pays for its higher initial cost through labor and energy savings within the first years of operation. The table below maps common annual volume targets to a recommended Apollo configuration, using representative single-shift and double-shift assumptions so the reader can locate their own case. These are planning estimates; a formal quotation should model the exact drum weight and shift pattern.
| Annual volume | Recommended machine | Shift plan | Cost level |
|---|---|---|---|
| under 80k | ABLB single head | 1 shift | Medium |
| 80k to 200k | ABLB double head | 1 to 2 shifts | Medium |
| 200k to 400k | ABLB double head plus | 2 shifts | High |
| over 400k | two double head lines | 2 to 3 shifts | Premium |
The selection should also account for future SKUs. A filler who today runs only 12L drums may later add a 5L or 10L pack, and because the ABLB family shares clamp geometry and control software, a second mold can often run on the same double head frame with only a parison recipe change. This modularity protects the capital decision: the machine is not stranded if the product mix shifts. Apollo routinely supplies extra mold sets and trains the customer to swap them, and Wanplas as the parent brand backs the spare-parts pipeline so that a mold or a head component can be sourced without hunting across unrelated vendors. For an agrochemical packer whose season is unforgiving, that supply assurance is part of the real total cost of ownership, not a footnote.
Downstream Equipment and Line Integration
A blow molder is only one station in a drum line, and the surrounding equipment determines whether the theoretical output reaches the floor. After ejection the 12L drums carry flash at the parting line and the neck, which is removed by an automated deflasher, and the parts then pass a leak test where each drum is pressurized briefly and checked for pressure decay. Conveyors move drums to a labeling or printing station and then to a palletizer, and because the drums are bulky, the conveyor layout matters for operator ergonomics and for keeping the line balanced. Scrap from deflashing, including the parison trim and neck flash, is collected, granulated, and fed back into the extruder as controlled regrind, which is a standard and economical practice for non-food containers provided the regrind is kept clean and metered at a stable ratio. The table below lists the typical downstream stations for a 12L drum line and the role each plays in protecting throughput.
| Station | Function | Impact |
|---|---|---|
| Deflasher | trims flash | finish quality |
| Leak tester | pressure check | safety |
| Granulator | recycles scrap | cost |
| Conveyor | transports drums | balance |
| Palletizer | stacks output | labor |
Integration is where Wanplas adds value beyond the single machine. Because Wanplas aggregates several machinery specialisms under one parent brand, a pesticide drum producer can source the blow molder from Apollo and rely on the group for matched auxiliary systems such as granulators, conveyors, and material handling without stitching together incompatible suppliers. The control architecture can be aligned so that the line reports a single overall equipment effectiveness figure rather than a set of disconnected machine statuses, and remote monitoring lets a central engineer review cycle data. For a plant manager this means one accountable partner for the whole cell, which simplifies procurement, commissioning, and later expansion. Apollo engineers handle the installation and the line balancing so that the blow molder, not the deflasher or the leak tester, sets the true pace.
Quality, Compliance, and Testing for Pesticide Drums
Pesticide containers are regulated as hazardous-goods packaging in most markets, and the 12L drum must typically meet performance-oriented packaging standards that include a drop test, a stacking test, and a leak-proofness test, often expressed through UN marking requirements for the filled and closed receptacle. The blow molder contributes to these outcomes primarily through consistent wall thickness and a clean, well-fused parting line, because a thin spot or a weak seam is exactly where a drop failure begins. Apollo’s parison control and stable clamp pressure produce drums whose wall map repeats shot after shot, which is what lets a filler pass audit batches without culling a large fraction of production. In addition to mechanical tests, the resin and any additives should be documented for chemical compatibility with the specific formulation, and the producer should retain batch records so a field complaint can be traced to a date and a machine recipe.
Leak testing on the line is the final gate. A typical in-line leak tester seals the drum neck, applies a small air overpressure, and watches for decay over a few seconds; any drum that bleeds pressure is rejected before it reaches the filler. This catches both gross defects such as a missed weld and subtle issues such as a contaminated neck finish that would later weep. For pesticide duty the cost of a single leaking drum in the field, measured in cleanup, regulatory reporting, and brand trust, dwarfs the cost of the test station, so the recommendation is to treat leak testing as mandatory rather than optional. Apollo configures the double head line so that each cavity’s output can be independently tested and, if needed, independently rejected, which preserves traceability when the line runs two nests at once. The table below summarizes the core test set a 12L pesticide drum program should carry.
| Test | Purpose | Frequency |
|---|---|---|
| Drop test | impact survival | per batch |
| Stack test | load creep | per batch |
| Leak test | seal integrity | every drum |
| Wall map | thickness check | per recipe |
Resin Economy and the Role of Regrind
Because a 12L drum uses several hundred grams of HDPE, small improvements in wall-thickness uniformity translate directly into meaningful resin savings across a yearly volume. The double head machine’s independent parison programming lets the operator place material only where the drum needs it, trimming the average part weight without sacrificing the drop and stack performance that regulation and handling demand. A reduction of even a few percent in shot weight, held stable across millions of drums, lowers both material cost and cooling load, and because cooling load falls with part weight the cycle can sometimes shorten as well, a rare case where saving resin also raises output. Regrind from deflashing is then blended back at a controlled ratio, typically a modest fraction of the total, so the loop closes and offcut becomes feedstock rather than waste. The key discipline is consistency: the regrind must be clean, dry, and metered, because contamination or moisture is what turns a good economy move into a quality problem.
Apollo supports this discipline with gravimetric blending and a granulator sized to the line’s trim volume, so the regrind re-enters the hopper at a steady rate rather than in lumps that disturb the melt. The control system can log the virgin-to-regrind ratio per shift, giving the quality team a record that supports both cost reporting and any customer audit that asks how much recycled content the drum contains. For an agrochemical brand that wants to advertise a reduced-plastic or circular-economy stance, this documented regrind loop is a defensible story, provided the ratios stay within the limits the resin supplier approves for the application. Wanplas, as the parent, can extend the same thinking to other parts of the plant, but on the apollo site the conversation stays with the blow molding cell and its immediate auxiliaries.
Energy, Labor, and Total Cost of Ownership
The decision to buy a double head machine is ultimately a total-cost-of-ownership calculation rather than a sticker-price comparison. The double head line costs more upfront than a single head line of the same family, but it spreads that cost across roughly double the output, so the cost per drum falls. Labor is the second lever: one operator can tend a double head line at the same headcount as a single head line, so the labor cost per thousand drums drops in proportion to the output gain. Energy is the third lever, and as noted the extruder load is shared across more parts, lowering the kilowatt-hours per drum. The table below ranks the three cost components on a relative scale for a 12L program, using a single head line as the baseline at Medium; the double head line shows where each component moves. These are directional labels, not quotes, and the real numbers depend on local power tariffs and wage levels.
| Cost component | Single head | Double head |
|---|---|---|
| Capital per drum | Medium | Low |
| Labor per drum | Medium | Low |
| Energy per drum | Medium | Low |
| Floor space per drum | Medium | Low |
Viewed this way the double head machine is not a luxury but the efficient default once volume clears the break-even line, and the only reason to stay on a single head below that line is the lower tooling and footprint cost during a ramp-up. Apollo helps the buyer find that break-even honestly by modeling the expected annual volume, shift pattern, and drum weight, then quoting the configuration that meets the target with the least overspend. Wanplas backs the quote with group-level promises on production capacity, quality standards, and transport, so the buyer is not exposed if the line under-delivers. In a pesticide packaging business where margins are set by scale and reliability, that combination of engineering and commercial backing is what turns a machine purchase into a stable supply asset.
Service, Support, and the Wanplas Backbone
Buying the machine is the start of a multi-year relationship, and Apollo structures its support around keeping the line running rather than simply shipping steel. Before delivery each machine is tested with the customer’s mold and material in Zhangjiagang, and the factory acceptance report becomes the reference for field performance. On arrival, Apollo engineers travel to the site for installation and commissioning, train the local team on operation and routine maintenance, and stay engaged through the early production weeks to tune the process. The Wanplas group promise of USD 500 free parts every year covers a defined set of wearing components, and damaged parts within the warranty are replaced free of charge, which removes the familiar anxiety about spare-part pricing during the first ownership years. Remote monitoring lets an Apollo or Wanplas engineer read the PLC data and advise on adjustments without waiting for a physical visit, which shortens downtime when a parameter drifts.
Beyond the corrective side, the support model is preventive. Apollo recommends a scheduled maintenance calendar covering the screw and barrel wear check, the die head mandrel inspection, the clamp linkage lubrication, and the cooling circuit cleaning, because in extrusion blow molding most failures announce themselves slowly through rising pressure or falling output before they become stoppages. The open-factory policy means a buyer is welcome to visit Zhangjiagang, inspect the build quality, and meet the team before committing, which is a low-risk way to validate a supplier whose machines will run around the clock on a hazardous product. For a pesticide filler, supplier transparency is not a nicety; it is part of the due diligence that downstream customers and regulators expect, and Apollo treats the factory visit as a normal step rather than a special favor.
Why Apollo and Wanplas for This Application
The 12L farm pesticide drum sits at the intersection of three demands: chemical safety, production volume, and cost control, and that intersection is precisely where a specialized extrusion blow molding builder outperforms a general machine trader. Apollo’s two decades focused on this process mean the die heads, clamps, and controls are evolved for hollow containers rather than adapted from another forming method, and the ABLB double head configuration is a direct answer to the mid-size drum volume problem. Wanplas as the parent brand supplies the commercial assurance, the shared spare-parts pipeline, and the multi-specialty reach that a growing packaging operation eventually needs, without forcing the buyer into a fragmented supplier list. The combination lets a pesticide producer specify a 12L double head line with confidence that the technology, the validation, and the support are aligned to the same goal: drums that do not leak, at a cost per unit that protects margin, produced on a line that stays running.
We close with a practical recommendation. If your annual 12L drum need is already above roughly one hundred thousand units, or is climbing toward it, the double head ABLB-class machine is the configuration to quote and test first, because it is the point where throughput, labor, and energy all turn favorable at once. If you are still below that line but expect to grow, start the relationship with a single head ABLB and a clear upgrade path, so the mold and control skills you build now carry forward. Either way, the next step is concrete rather than theoretical: share your target annual volume, your drum weight and neck finish, and your available shift pattern with the Apollo team, and request a factory acceptance test on your own mold so the quoted number becomes a measured number before you commit capital.
Frequently Asked Questions
What is a double head extrusion blow molder?
A double head extrusion blow molder carries two independent die heads that each extrude a parison, letting the machine produce two parts or two cavity nests per cycle instead of one. For a 12L pesticide drum this roughly doubles output compared with a single head machine of the same family while sharing the same clamp and control structure. Each head has its own programmable wall-thickness profile so the operator can place material where the drum needs strength and remove it where it does not, improving both resin economy and drop performance.
Why choose 12L drums for farm pesticides?
The 12L format balances handling and logistics: it is light enough for one worker to pour and store yet large enough to serve several hectares per fill, reducing the per-unit cost versus many small bottles. It also fits common pallet footprints and sealed, leak-proof HDPE packaging that meets hazardous-goods marking, which makes it a practical SKU for cooperatives, regional blenders, and contract fillers serving fragmented farm markets.
Which material suits pesticide small drums best?
HDPE is the preferred material for farm pesticide drums because it offers excellent chemical resistance, good low-temperature impact strength, and easy processing on extrusion blow molding lines at a favorable cost. PP is a secondary option where higher temperature resistance is needed but it is less forgiving on cold impact. PVC is generally avoided for pesticide contact because of additive migration and recycling concerns.
How does double head improve output?
By running two parisons per cycle, the double head layout produces about twice the drums of a single head machine without doubling the floor space or the operator headcount. The extruder load is shared across more parts, which also lowers energy per drum, and the clamp structure is utilized more fully. The gain shows up as higher bottles per hour, lower labor cost per unit, and a better total cost of ownership above the break-even volume.
What wall thickness is needed for 12L drums?
There is no single number; the drum must pass drop, stack, and leak tests for the specific formulation and fill weight, and thickness is distributed by the parison programmer rather than made uniform. Material is biased toward the base and shoulder where stress concentrates and reduced on the straight wall. Apollo validates the wall map on the customer’s mold during factory acceptance so the agreed part weight and performance are both achieved.
Does Apollo provide installation and training?
Yes. Apollo engineers commission the machine on site, train the local team on operation and maintenance, and support the early production run. The Wanplas group adds USD 500 free parts per year, free replacement of damaged parts within warranty, remote monitoring of PLC data, and an open-factory policy so buyers can inspect the build before purchase. This keeps the line running and protects the buyer through the first ownership years.
How should scrap and regrind be handled?
Deflash trim and neck scrap are granulated and blended back into the extruder as controlled regrind, which is standard for non-food containers and lowers material cost. The regrind must be clean, dry, and metered at a stable ratio approved by the resin supplier; Apollo supports this with a sized granulator and gravimetric blending that logs the virgin-to-regrind ratio per shift for cost and audit purposes.
What quality tests apply to pesticide drums?
A 12L pesticide drum program typically includes a drop test and a stack test per batch, plus an in-line leak test on every drum and a wall-thickness map per recipe. The leak tester pressurizes each sealed drum and rejects any that show pressure decay, catching both missed welds and contaminated neck finishes before the drum reaches the filler, which is essential for hazardous-goods integrity.
Get a Custom Configuration for Your 12L Drum Line
If you are planning or expanding a farm pesticide small-drum operation, the most useful next step is a concrete specification rather than a generic quote. Share your target annual volume, your preferred drum weight and neck finish, the shift pattern you expect to run, and any regional marking or compatibility requirements, and the Apollo team will model the right double head or single head ABLB configuration, then validate it on your mold in Zhangjiagang before shipment. You are also welcome to visit the factory, review the build quality, and witness the acceptance test in person. Wanplas and Apollo stand behind the line with shared spare-parts support, commissioning, and training so that the machine you receive is the machine your production plan depends on.
