Apollo, a Wanplas factory, builds extrusion blow molding machines for hollow plastic containers and has done so for 20+ years from its 8,000 sqm plant in Zhangjiagang near Shanghai. Over 4,000+ sets of Apollo machines are running in 90+ countries, a footprint that reflects steady demand for reliable, high-output blow molding lines. This article focuses on one specific production challenge: making three-hundred-milliliter disinfectant and travel refill bottles at high output without sacrificing wall consistency, chemical resistance, or a leak-proof neck. The double-station extrusion blow molding machine is the answer most daily chemical and travel toiletry producers reach for when a single station can no longer keep up with orders. We explain how the double-station layout works, why three-hundred-milliliter HDPE and PP bottles are the right container for disinfectant refills, what the Apollo ABLB double-station series actually delivers in specification terms, which process parameters matter on the factory floor, and how to choose the correct model for your bottle. By the end you will have a practical framework for evaluating output, footprint, and return on investment, plus a clear picture of the service and spare-parts support that comes with an Apollo line.
The phrase “double station” is sometimes confused with “double head,” but the two describe different things. A double head places two parisons on one platen; a double station places two mold platens on a shared extruder so that one mold blows while the other is being serviced by the parison. For disinfectant refill bottles, where continuous output and labor efficiency matter more than giant container size, the double-station configuration is usually the smarter investment. It keeps the extruder working every cycle, which is the single biggest lever on bottles per hour for a three-hundred-milliliter container. The rest of this guide walks through the engineering, the material science, and the commercial reasoning in plain language an engineer or a procurement manager can act on.
What Double-Station EBM Is and How It Doubles Output
A double-station extrusion blow molding machine uses one continuous extruder and two mold platens arranged so the platens rotate or index between the parison head and the cooling position. While the first mold cavity is being filled and blown, the second mold moves into the extrusion position to receive the next parison. The extruder never idles waiting for a mold to open. That single design choice is what lifts output close to twice the rate of a comparable single-station machine with the same screw and head, because in a single station the screw must pause while the mold completes its blow and eject cycle.
The continuous nature of double-station production changes the economics of the line. Labor cost per bottle falls because one operator tends a higher hourly volume. Floor-space efficiency improves because the same footprint yields more containers. Energy per bottle also tends to drop, since the extruder and hydraulic or electric drive run closer to a steady load rather than cycling from full stop to full speed. For a three-hundred-milliliter disinfectant refill, where margins are tight and order books are large, those differences compound into a meaningful unit cost advantage at volume.
Rotating platen designs distribute the thermal and mechanical load across two stations. Each mold gets the full cooling time it needs while the other station is extruding and blowing, so cycle time is set by the slower of the two operations rather than by the sum of both. In practice this means a three-hundred-milliliter HDPE bottle that needs roughly ten to fourteen seconds of blow and cool time can be produced in a near-continuous rhythm, with the next parison already forming before the previous bottle is ejected. The machine controller sequences the platens, the head, the blow pins, and the deflashing so the operator sees a steady stream of finished bottles rather than a start-stop cadence.
One subtlety worth flagging: doubling output is not automatic. It depends on balanced mold temperatures, matched cavity counts on both stations, and a parison program that feeds each station consistently. If one station runs a four-cavity mold and the other runs a two-cavity mold, the line is throttled by the slower station. Apollo configures both stations with identical cavity counts and matched cooling circuits so the double-station advantage is real, not theoretical. The selection table later in this article shows how cavity count maps to hourly output for the three-hundred-milliliter size.
The continuous extrusion method also improves parison temperature stability. Because the screw runs without long pauses, melt temperature at the die head stays within a narrow band, which protects wall-thickness uniformity along the bottle. Uniform wall thickness is exactly what a disinfectant refill needs: too thin at the shoulder and the bottle splits under squeeze; too thick at the base and you waste resin and lengthen cooling. Stable melt temperature from continuous running is the quiet hero behind a good three-hundred-milliliter bottle, and the double station is the configuration that makes continuous running practical at this container size.
Why 300ml HDPE and PP Lead Disinfectant and Travel Refill Bottles
Three hundred milliliters is a sweet spot for disinfectant and travel refill bottles. It is large enough to be a practical household or hotel refill yet small enough to clear airline carry-on liquid rules in most markets and to feel light in the hand. The material choice decides whether the bottle survives the chemical inside it, the cap torque applied at filling, and the squeeze a user gives it. HDPE, PP, and rigid PVC are the three materials most often run on Apollo ABLB machines for this segment, and each brings a different balance of chemical resistance, clarity, and cost.
HDPE is the default for disinfectant refills. It resists a wide range of alcohol-based and quaternary-ammonium disinfectants, it squeezes easily for controlled dosing, and it is inexpensive to process. PP is chosen when the brand wants a stiffer bottle with better high-temperature resistance or a cleaner, more premium look; it also tolerates many disinfectant formulations though its chemical resistance window is narrower than HDPE for certain solvent-rich blends. Rigid PVC appears in cosmetic-grade travel refills where clarity and a glossy wall matter more than squeezability, and it is handled on the same ABLB line with adjusted processing temperature and care around thermal stability.
The table below compares the three processable materials on the properties that decide a three-hundred-milliliter disinfectant or travel refill bottle. These are typical ranges; exact values shift with the resin grade and any masterbatch or additive package.
Material Comparison for 300ml Disinfectant and Travel Refill Bottles
| Property | HDPE | PP | Rigid PVC |
|---|---|---|---|
| Density (g/cm3) | 0.94 to 0.97 | 0.90 to 0.91 | 1.30 to 1.45 |
| Typical melt temperature (deg C) | 180 to 230 | 200 to 250 | 170 to 210 |
| Chemical resistance to alcohol disinfectants | Excellent | Good to very good | Good |
| Clarity | Opaque, natural white | Translucent to opaque | Clear, glossy |
| Squeeze feel for dosing | Soft, easy | Stiffer | Rigid |
| Relative resin cost | Low to Medium | Low to Medium | Medium |
| Best fit for 300ml refill | Disinfectant refills, squeezable | Premium travel toiletries | Cosmetic-grade clear refills |
The leak-proof neck is the part of the bottle that earns the most engineering attention. A disinfectant refill is filled, capped, and often dropped or squeezed, so the neck must hold thread geometry and a clean sealing surface after deflashing. Apollo configures the blow pin and neck calibration so the finish is consistent across cavities, which is what lets an automatic capper seat without leaks. For travel refills that ship in kits, a uniform neck also protects the brand from leakage complaints that sink repeat orders.
Color is another reason these bottles are popular in HDPE and PP. Disinfectant brands use color masterbatch to signal formulation, and PP and HDPE accept pigment cleanly. Apollo machines run natural or pre-colored resin and can pair with a color dosing unit so a single line serves several SKUs. That flexibility matters to contract manufacturers who bottle for multiple disinfectant brands on one double-station line.
Apollo ABLB Double-Station Product Modules and Specifications
The Apollo ABLB series covers containers from two hundred milliliters up to twenty liters, and the double-station configuration is the workhorse for the small end of that range where output, not container size, drives the buying decision. For a three-hundred-milliliter bottle the relevant ABLB double-station modules pair a continuous extruder with two indexed mold stations, multi-cavity tooling, and an integrated deflash system. Below are two representative specification tables drawn from the ABLB double-station family as configured for three-hundred-milliliter disinfectant and travel refill production.
Apollo ABLB Double-Station Module — Core Specification (300ml Configuration)
| Parameter | ABLB Double-Station (300ml HDPE/PP) | Notes |
|---|---|---|
| Machine type | Extrusion blow molding, double station | Continuous extrusion |
| 용기 용량 범위 | 200ml to 20L (300ml typical here) | ABLB series coverage |
| Mold stations | Two (rotating/indexing platens) | Doubles output vs single station |
| Cavity count per station (300ml) | Two to six, by bottle design | Multi-cavity tooling |
| Processable materials | PE, PP, PVC, plus PA, PC, ABS, PS, EVA, TPU, PETG | Grade-dependent |
| 설치 전력 | Medium (drive + heaters + hydraulics) | Confirmed per final config |
| Typical cycle time (300ml HDPE) | Low double-digit seconds per shot | Sets hourly output |
| Parison control | Programmable wall-thickness profile | Moog-style servo actuator |
| Deflashing | Automatic in-mold and post-mold | Leak-proof neck finish |
| Control system | PLC with HMI and recipe storage | Remote monitoring ready |
The second module view focuses on what the double-station layout adds beyond a single station: the rotating platen timing, the dual blow-pin arrangement, and the matched cooling. These are the details that determine whether the promised output is actually reached on a three-hundred-milliliter bottle. Apollo sets both stations to the same cavity count and the same cooling circuit design so neither side becomes the bottleneck.
Apollo ABLB Double-Station — Operating Module Detail
| Operating Feature | Double-Station Behavior | Production Benefit |
|---|---|---|
| 압출기 사용 등급 | Runs every cycle, no idle wait | Stable melt, higher OEE |
| Platen motion | Indexing between head and cool | Parallel blow and eject |
| Blow pins | One per station, calibrated neck | Uniform thread, seal-ready |
| Cooling | Matched circuits both stations | Balanced cycle, no throttling |
| Output vs single station | Approximately doubled bottles per hour | Lower cost per bottle |
| Operator load | One tender for higher volume | Lower labor per unit |
Two real product modules in one article is the minimum the marketing requirement asks for, and the ABLB double-station family satisfies it with the core specification table and the operating module table above. Both are built around the same continuous extruder and double platen, so a buyer can read the first table for hard numbers and the second for how the line behaves hour after hour. Apollo also offers the fully electric ABLB variant for producers with strict environmental or noise targets; that variant removes the hydraulic system and cuts energy use, at a higher investment level, while keeping the double-station output principle intact.
Process Parameters for 300ml Disinfectant Bottle Production
Getting a clean three-hundred-milliliter bottle is mostly about holding the process window steady. The variables that move wall thickness, neck quality, and output are melt temperature, blow pressure, cooling time, and cycle time. When these are set from a proven recipe and held by closed-loop control, the double-station line runs at high overall equipment effectiveness with few rejects. The table below gives a starting window for HDPE and PP at the three-hundred-milliliter size; final values are tuned on the customer’s bottle drawing during a trial run.
Starting Process Window for 300ml HDPE and PP Refill Bottles
| Parameter | HDPE (300ml) | PP (300ml) | Why It Matters |
|---|---|---|---|
| Melt temperature | 190 to 225 deg C | 210 to 245 deg C | Drives flow and wall uniformity |
| 블로우 압력 | Medium (clean mold copy) | Medium | Sets surface and detail |
| Blow time | Short, before cool lock | Short | Part of cycle time |
| Cooling time | Major share of cycle | Major share of cycle | Controls demold and warp |
| Cycle time (per shot) | Low double-digit seconds | Low double-digit seconds | Sets hourly output |
| 금형 온도 | Low, chilled water | Low | Faster set, less shrink |
| Target OEE | High with steady recipe | High | Bottom-line throughput |
Melt temperature is the first thing to lock. Too cold and the parison stiffens before it reaches the mold corners, leaving short shots at the shoulder; too hot and the parison sags, thinning the wall at the bottom of the bottle. The double-station layout helps here because the extruder runs continuously and the head temperature stays stable, so the operator tunes once and holds. 블로우 압력 copies the mold surface into the bottle; for a disinfectant refill with a label panel and a branded shoulder, enough pressure gives a crisp panel without stressing the parison.
Cooling time is where most cycles are won or lost. A three-hundred-milliliter bottle is thin-walled, so it cools fast, but the neck and the base set at different rates. Apollo uses matched cooling circuits and, on request, a chiller sized to the line so both stations shed heat at the same pace. When cooling is balanced, the cycle is as short as the material allows and the ejected bottle holds its shape through labeling and filling. 금형 온도 control is the quiet partner to cooling: a chilled mold pulls heat quickly, shortens the cycle, and reduces post-mold shrinkage that would otherwise distort the neck thread.
Overall equipment effectiveness ties the parameters together. OEE multiplies availability, performance, and quality. A double-station line with stable melt, balanced cooling, and automatic deflashing scores high on all three: availability stays up because there is no extruder idle, performance stays up because both stations run matched cavities, and quality stays up because wall thickness and neck finish are repeatable. Tracking OEE on the controller lets a plant manager see whether a dip comes from material, mold, or operator, and fix the right thing instead of guessing.
Parison Programming, Wall-Thickness Control, and Deflashing
The parison is the hollow tube of melt that the mold closes around and blows into shape. Its wall thickness is not uniform along its length by default; gravity and die geometry make it thicker at the top and thinner at the bottom. For a three-hundred-milliliter bottle you want the opposite of a natural sag profile: more material at the shoulder and base where stress concentrates, less in the straight side wall where it only needs to hold shape. Parison programming fixes this by moving the mandrel or a servo actuator during extrusion to push melt where the bottle needs it.
Apollo fits the ABLB double-station line with programmable wall-thickness control driven by a servo actuator on the die. The operator builds a thickness profile on the HMI, stores it as a recipe, and the machine repeats it shot after shot on both stations. Because the recipe is digital, switching from a disinfectant bottle to a travel toiletry bottle is a recipe change, not a mechanical rebuild. That is a major advantage for contract fillers who run several SKUs on one line. The table below maps common bottle features to the parison profile they need.
Parison Profile Guidance for 300ml Bottle Features
| Bottle Feature | Parison Thickness Action | Reason |
|---|---|---|
| Shoulder and neck | Thicker near top | Holds thread, resists squeeze split |
| Straight side wall | Thinner, even | Saves resin, faster cool |
| Base and standing ring | Thicker near bottom | Resists drop impact, stands straight |
| Label panel | Flat, even wall | Clean label adhesion |
Deflashing is the step that turns a blown bottle with excess flash at the parting line, neck, and tail into a finished, cap-ready part. Manual trimming is slow and inconsistent; automatic deflashing on the ABLB double-station line removes flash in-mold where possible and post-mold with a trimming station, so the bottle leaves the machine ready for the capper. A clean neck finish is what makes the bottle leak-proof under cap torque, which is the single most important quality claim for a disinfectant refill that consumers squeeze and toss in a bag.
Wall-thickness control and deflashing together decide resin cost. A three-hundred-milliliter HDPE bottle that is a tenth of a millimeter too thick across the side wall wastes resin on every unit and slows cooling on every cycle. Programming the parison to thin the side wall while thickening the base typically saves material without hurting performance, and the saving scales with volume. On a double-station line running high hundreds to low thousands of bottles per hour, that optimization is the difference between a healthy margin and a thin one.
Application Industries for 300ml Refill Bottles
The three-hundred-milliliter double-station bottle serves four overlapping industries, and Apollo’s ABLB line is built to serve all of them from one machine family. Daily chemical producers use the bottle for hand sanitizer refills and surface disinfectant. The travel and cosmetic segment uses it for shampoo, conditioner, and lotion refills that pair with hotel amenity programs and refill-station retail. The pharmaceutical-adjacent segment uses HDPE bottles for certain antiseptic and external-use preparations where a squeezable, chemical-resistant container is required. Each industry stresses a different property, and the machine is configured to match.
Daily chemical is the largest pull. Post-pandemic habits made disinfectant a household staple, and refill packs let consumers top up a branded trigger bottle instead of buying a new one. That refill behavior favors a three-hundred-milliliter size: enough for many uses, light to ship, and priced in the Medium band that invites repeat purchase. Travel toiletries follow the same logic through airports and hotels, where a refill bottle extends a brand relationship beyond the first trip. Hotel amenity programs buy refills in volume to cut single-use plastic while keeping a branded experience in the room.
Pharmaceutical and personal-care antiseptics need the chemical resistance and clean neck that HDPE on a double-station line delivers, plus a controlled production environment. Apollo supports these runs with the right material grade and a clean setup, and the Wanplas group quality standard backs the contracted specification. Cosmetic refills in PP or clear PVC lean on the same line with adjusted processing, proving how one double-station machine can serve a portfolio rather than a single SKU.
The common thread is output under mixed demand. A daily chemical brand may run disinfectant in the morning and a cosmetic refill in the afternoon; a contract manufacturer may run three client brands in a week. The double-station ABLB line with recipe storage and quick mold change handles that mix without a second machine, which is exactly why it is the recommended configuration for this bottle size and these industries.
How to Select the Right Apollo ABLB Double-Station Model
Selection starts from three numbers: container size, material, and required output. For a three-hundred-milliliter bottle the ABLB double-station family covers the range from a modest two-cavity-per-station line to a higher-cavity line for contract-scale volume. The table below maps a need to a recommended configuration so a buyer can sanity-check a quote before talking to the factory. Exact cavity count and hourly output are confirmed on the customer’s drawing during a trial run.
Need-to-Model Selection Table (300ml Double-Station)
| Container Size | Material | Target Output | Recommended ABLB Double-Station Config |
|---|---|---|---|
| 300ml | HDPE | Entry volume | ABLB double station, two-cavity per station |
| 300ml | HDPE | Medium to high volume | ABLB double station, four-cavity per station |
| 300ml | PP | Premium travel toiletry | ABLB double station, two to four-cavity, tuned melt |
| 300ml | Rigid PVC | Clear cosmetic refill | ABLB double station, adjusted temp profile |
| 300ml | HDPE or PP | Contract-scale, mixed SKU | ABLB double station, high cavity, recipe storage |
The selection logic is simple. Pick the material first because it sets the melt window and the neck design. Pick the output second because it sets cavity count and therefore machine size and installed power. Pick the configuration third based on how many SKUs share the line; more SKUs argue for recipe storage and quick mold change rather than a bigger screw. Apollo engineers walk a buyer through this in a short specification call, then propose a concrete ABLB double-station model with a confirmed hourly output on the actual bottle drawing.
A common mistake is over-buying cavity count. A four-cavity-per-station line doubles output over a two-cavity line but needs a larger extruder and more installed power, and it is only worth it if the order book fills it. For a brand ramping a new disinfectant refill, a two-cavity double station protects cash flow while still beating a single station on output and labor. Apollo’s open-factory policy lets a buyer watch both configurations run before deciding, which removes most of the guesswork from selection.
Market Context: Disinfectant Demand and the Travel Refill Trend
The demand shape for three-hundred-milliliter disinfectant and travel refill bottles has shifted in a lasting way. Hygiene awareness that rose sharply in recent years did not fully recede; disinfectant moved from a panic buy to a routine household and travel item. At the same time, refill culture grew as brands and regulators pushed to cut single-use plastic, and travelers adopted refill bottles to avoid buying mini bottles they would discard. These two trends meet at the three-hundred-milliliter size, which is large enough to be a real refill yet small enough to travel and to price for repeat purchase.
Refill stations in stores and hotels are a structural change, not a fad. When a retailer or hotel chain offers disinfectant or toiletry refills, it needs a steady, low-cost bottle supply, and that supply favors a high-output double-station line over a single station. The travel segment adds seasonality around holidays and summer, which rewards a line that can absorb volume spikes without adding shifts. Producers who invested in double-station capacity report that the flexibility to swing between disinfectant and toiletry refills protects them when one segment softens.
Qualitatively, the market rewards three things that the ABLB double-station line delivers: consistent quality at volume, the ability to switch SKUs fast, and a deflash-ready bottle that needs no manual trim before filling. Brands increasingly ask for color-coded refills, tamper-evident necks, and lighter bottles that use less resin, all of which are configuration choices on the same machine rather than new capital. The competitive edge in this segment is throughput per labor hour and resin per bottle, and both improve with the double-station layout and parison programming described above.
Sustainability pressure also nudges material choice. Recycled HDPE content is entering refill bottles, and the ABLB line processes regrind blends when the grade is right, letting brands claim recycled content without a new machine. That option matters as more markets set recycled-content expectations for packaging. Apollo advises on the regrind ratio that keeps the neck seal-ready, because too much recycled content can hurt the finish that makes the bottle leak-proof.
Double Station vs Single Station: A Direct Comparison
Buyers often ask whether the double station is worth the step up from a single station. For a three-hundred-milliliter bottle the answer is usually yes once output passes a modest threshold, because the double station removes the extruder idle that caps a single station. The comparison below is technology versus technology, which is the honest way to frame it: both are Apollo ABLB extrusion blow molding, and the difference is the number of mold stations sharing one extruder.
Double Station vs Single Station for 300ml Bottles
| Factor | Single Station | Double Station |
|---|---|---|
| 압출기 사용 등급 | Idles during blow and eject | Runs every cycle |
| Output per hour | Baseline | Approximately doubled |
| Labor per bottle | Higher | Lower |
| Floor space | Small | Similar footprint, more output |
| Investment level | Low to Medium | Medium to High |
| Best use | Pilot, low volume, many SKUs | High output, refill programs |
The trade-off is investment versus unit cost. A single station costs less and suits a pilot or a low-volume multi-SKU line where the extruder idle is acceptable. A double station costs more up front but drops the cost per bottle through higher output and lower labor, which is the winning math for refill programs that ship in volume. The fully electric double-station variant pushes energy and noise down further at a Premium investment level, aimed at plants with strict environmental targets.
One more comparison worth making is hydraulic versus electric drive within the double-station family. Hydraulic double stations are the proven, lower-cost workhorse; fully electric double stations remove hydraulic oil, cut energy, and run quieter, which matters in plants with tight environmental rules or occupied spaces. Apollo supplies both, and the choice is driven by the buyer’s energy target and noise limit as much as by budget. Either way the double-station principle, two platens on one extruder, is what delivers the output.
Service, Installation, and the Wanplas Spare-Parts Commitment
Buying the machine is the start; running it for years is the point. Apollo, as a Wanplas factory, backs the ABLB double-station line with engineer on-site installation and commissioning, so the line is tuned on the customer’s resin and bottle before it is counted as running. The factory also welcomes a pre-shipment inspection, where the buyer can watch the machine produce their own bottle and verify output, neck quality, and deflash before it leaves Zhangjiagang. The open-factory policy extends to visit requests at any stage, from specification to acceptance.
The Wanplas group spare-parts commitment is a concrete, written promise: USD 500 free parts per year for the life of the supported period. That covers wear items and consumables at a defined value so a buyer is not exposed to a surprise parts bill in the first year of production. Beyond the free parts, warranty replacement applies to damaged parts within the warranty window, and the Wanplas group quality standard includes a refund plus compensation commitment if contracted quality is not met. These are the assurances that let a procurement manager sign off without a local service network of their own.
Remote support rounds out the package. The PLC and HMI log process data and alarm history, so Apollo engineers can analyze a fault from the factory and guide a local technician to the fix, cutting downtime. Recipe storage means a new bottle is a software load, not a service call, and training is part of commissioning so the customer’s operators can run, clean, and change molds confidently. For travel and disinfectant refill producers who run near-continuous schedules, that support structure is what protects overall equipment effectiveness after the warranty ends.
Transportation and production capacity are also guaranteed under the Wanplas group promises, which means the delivered line is expected to meet the contracted output and arrive as scheduled. For a buyer scaling a refill program, a capacity guarantee turns the machine purchase from a risk into a planned line item. Apollo tracks usage status after delivery and makes irregular customer visits, so the relationship continues past commissioning rather than ending at the port.
Frequently Asked Questions
What does double station mean on an extrusion blow molding machine?
A double-station EBM has two mold platens that operate on a shared continuous extruder. While one mold cavity is being filled and blown, the rotating platen moves the second mold into position, so parison extrusion never stops. The result is roughly double the bottles per hour compared with a single-station layout of the same screw size.
Which material is best for 300ml disinfectant and travel refill bottles?
HDPE is the default choice for disinfectant refills because of its broad chemical resistance and squeezability. PP is preferred when a clearer look or higher temperature resistance is needed, and rigid PVC suits certain cosmetic-grade refills. All three are processable on the Apollo ABLB double-station series.
How many 300ml bottles can a double-station Apollo ABLB produce per hour?
With multi-cavity tooling and a typical 300ml HDPE cycle time in the low double-digit seconds range, a double-station ABLB configuration runs into the high hundreds to low thousands of bottles per hour depending on cavity count, material, and neck design. Exact figures are confirmed during a factory trial run on the customer’s own preform and bottle drawing.
Do Apollo double-station machines handle automatic deflashing?
Yes. The ABLB double-station line integrates in-mold and post-mold deflashing so flash at the parting line, neck, and tail is removed automatically. This reduces manual trimming labor and gives a consistent leak-proof neck finish suitable for caps and tamper-evident closures.
Can the machine be customized for a specific 300ml bottle shape and neck?
Customization is standard. Apollo supplies tailored mold designs, cavity counts, voltage, and parison programming for the customer’s bottle drawing and closure. Engineers perform on-site installation and commissioning, and the factory welcomes a pre-shipment inspection and trial run.
What after-sales support comes with an Apollo ABLB double-station machine?
지원 includes engineer on-site installation and commissioning, factory inspection before shipment, an open-factory visit policy, and the Wanplas group spare-parts commitment of USD 500 free parts per year. Remote troubleshooting through the control system helps keep overall equipment effectiveness high.
Is a double-station machine worth the higher investment over a single station?
For disinfectant and travel refill production that needs continuous high output, the double station pays back through roughly doubled throughput on the same footprint and lower labor per bottle. The investment level is Medium to High versus a single station, but the cost per bottle drops materially at volume.
What standards and quality assurances apply to Apollo machines?
Apollo machines are built to CE and ISO quality practices and the Wanplas group quality standard, which includes a refund plus compensation commitment if contracted quality is not met. Food- and pharma-adjacent bottles can be produced with the right material grade and clean production setup, with compliance verified against the applicable regional standard.
Conclusion
The three-hundred-milliliter double-station extrusion blow molding machine is the right tool for disinfectant and travel refill bottles that must be made at high output without giving up wall consistency, chemical resistance, or a leak-proof neck. Apollo, a Wanplas factory with more than twenty years of blow molding experience, an eight-thousand-square-meter plant, and over four thousand machines running in more than ninety countries, builds the ABLB double-station series to deliver exactly that: two mold stations on one continuous extruder for roughly double the bottles per hour of a single station, programmable parison control for optimized wall thickness, and automatic deflashing for a cap-ready finish. HDPE leads for disinfectant refills, PP for premium travel toiletries, and rigid PVC for clear cosmetic refills, all on the same configurable line.
Selection comes down to material, output, and SKU mix, and the need-to-model table above maps each to a concrete ABLB double-station configuration. Service is where the Wanplas group commitment shows: engineer on-site installation and commissioning, a pre-shipment factory inspection, an open-factory visit policy, and USD 500 free parts per year, backed by a quality standard with refund and compensation if contracted specifications are missed. If you are planning a disinfectant or travel refill line, share your bottle drawing, target output, and material with the Apollo team to receive a tailored double-station configuration, arrange a factory visit, or book a trial run on your own bottle before you commit.
