1. Introduction to 30L EBM Machine
1.1 Definition and Core Industrial Positioning
A 30L EBM (Extrusion Blow Molding) machine is a heavy-duty industrial blow molding system specially engineered for mass production of medium-large hollow plastic containers ranging from 20 liters to 30 liters. As a core model of heavy-duty extrusion blow molding machine series, it fills the market gap between medium-sized 10L packaging equipment and large 50L+ industrial barrel production lines. This professional extrusion blow molding machine focuses on heavy-duty container manufacturing, covering small industrial chemical drums, purified water buckets, plastic storage barrels, industrial liquid packaging barrels, and daily large-capacity water storage containers.
Different from light-duty blow molding equipment for food and daily chemical small packaging, the 30L extrusion blow molding machine adopts reinforced mechanical structure, high-torque extrusion system, and high-pressure blow molding configuration. It is designed to produce thick-walled, high-strength plastic containers that can withstand heavy load stacking, chemical corrosion, and harsh outdoor storage environments. It has become the standard production equipment for medium-sized industrial packaging and civil large-capacity water storage products, widely adopted by chemical packaging factories, water treatment product manufacturers, and plastic container processing enterprises worldwide.
1.2 Core Application Scenarios and Industry Value
The 30L EBM machine has two core mainstream application scenarios: industrial chemical drum production and civil large-capacity water bucket production. In the industrial field, it manufactures 30L chemical solvent drums, reagent storage barrels, industrial detergent packaging barrels, and low-corrosive chemical storage containers. These products require excellent structural toughness, compression resistance, and corrosion resistance to adapt to industrial transportation and indoor and outdoor storage environments.
In the civil and commercial field, the equipment is dedicated to producing 30L pure water buckets, domestic water storage buckets, construction water storage barrels, and daily large-capacity plastic water containers. The finished products feature uniform wall thickness, strong pressure resistance, safe and non-toxic material performance, meeting civil water storage and commercial water supply equipment supporting needs. Compared with manual molding and semi-automatic small-scale equipment, the fully automatic 30L extrusion blow molding machine greatly improves product consistency, production efficiency, and product qualification rate, helping enterprises achieve standardized and large-scale production.
1.3 Advantages Over Traditional Blow Molding Equipment
Traditional ordinary blow molding machines have obvious limitations in 30L heavy-duty container production. Light-duty equipment has insufficient extrusion plasticizing capacity, unable to meet thick-walled container melt supply requirements, resulting in uneven wall thickness, insufficient structural strength, and easy deformation of finished products. Old-fashioned semi-automatic equipment requires a large amount of manual intervention, with low production efficiency, unstable batch quality, and high defective rate, which cannot adapt to modern industrial mass production needs.
The Apollo 30L EBM heavy-duty production line optimizes and upgrades the core structure for heavy-duty container production. It adopts a reinforced fuselage structure, high-torque servo extrusion system, and multi-point wall thickness precise control technology, which stably realizes one-time integral molding of 30L thick-walled containers. The fully automatic intelligent control mode reduces manual operation errors, improves production efficiency by more than 40% compared with traditional equipment, and reduces the product defective rate to below 1%, effectively lowering the comprehensive production cost of enterprises.
2. Standard Technical Parameters of Apollo 30L EBM Machine
2.1 Overall Equipment Configuration and Basic Parameters
The Apollo 30L EBM extrusion blow molding machine is a professional heavy-duty blow molding production line independently developed for 20-30L industrial and civil large-capacity plastic containers. The equipment is equipped with a heavy-duty extrusion system, high-rigidity hydraulic mold clamping system, intelligent wall thickness control system, and efficient circulating cooling system, with stable overall performance and strong continuous production capacity. The maximum product molding capacity is 30 liters, supporting flexible production switching of 20L, 25L, and 30L multi-specification containers, meeting diversified production needs of enterprises.
The equipment adopts a large-diameter high-efficiency plasticizing screw with a screw diameter of 85mm and a length-diameter ratio of 30:1, with a maximum plasticizing capacity of 280kg/h, which can efficiently and uniformly plasticize HDPE, MDPE, and modified polyolefin raw materials required for thick-walled heavy-duty containers. The mold clamping force is stably maintained at 180 tons, with high mold closing rigidity, effectively avoiding mold expansion and product flash during high-pressure blow molding of thick-walled products, ensuring smooth and flat product edges and stable overall dimensions.
The whole machine supports 24-hour uninterrupted continuous industrial production, with an equipment operation stability rate of over 99%. The single product molding cycle is 75-90 seconds, with an hourly output of 40-50 pieces of 30L standard containers. The finished product wall thickness tolerance is controlled within ±0.3mm, far exceeding the industry standard for heavy-duty plastic containers, ensuring uniform structural strength of finished products.
2.2 Core System Performance Parameters
In terms of temperature control system, the Apollo 30L extrusion blow molding machine adopts segmented independent intelligent temperature control, covering the feeding section, compression section, metering section, die head, and mold temperature zone, with temperature control accuracy up to ±1℃. It can accurately match the plasticization temperature requirements of different raw materials, avoid insufficient plasticization or thermal decomposition of raw materials, and ensure the uniformity and stability of molten parison.
The hydraulic servo mold clamping system adopts imported hydraulic components and closed-loop servo control technology, with stable mold opening and closing speed, precise positioning, and low vibration and noise. The high-pressure air blowing system provides stable and adjustable blowing pressure, which can meet the molding requirements of thick-walled industrial drums and water buckets, ensuring that the molten parison is fully attached to the mold wall and the internal structure of the product is compact and free of gaps.
The intelligent parison wall thickness control system supports 12-point automatic thickness adjustment in the whole parison section, which can dynamically optimize the wall thickness distribution according to the structural stress characteristics of 30L containers. It realizes thickening reinforcement at the bottom and mouth of the container and uniform thinning of the barrel body, which not only improves the compression resistance and drop resistance of the product but also saves raw material consumption and reduces unit production cost.
2.3 Adaptable Raw Materials and Product Specifications
The Apollo 30L EBM machine has strong raw material adaptability, suitable for high-density polyethylene, medium-density polyethylene, modified anti-corrosion polyolefin, and other raw materials. It can produce industrial-grade anti-corrosion chemical drums, food-grade safe water storage buckets, and general-purpose plastic storage barrels by adjusting formulas and process parameters.
The finished 30L container products have standard outer diameter and height dimensions, with customizable wall thickness ranging from 2.5mm to 4mm. The products have excellent physical properties, with a stacking bearing capacity of more than 120kg, a drop resistance height of 1.8 meters without cracking, and excellent acid and alkali corrosion resistance, fully meeting industrial chemical packaging and civil water storage use standards.
3. Complete Production Process for 30L Industrial Drums & Water Buckets
3.1 Raw Material Screening, Drying and Formula Mixing
The production of 30L heavy-duty containers puts forward higher requirements on raw material purity and dryness. Before formal production, plastic particles need to be strictly screened to remove deteriorated particles, impurity particles, and oversized particles, preventing black spots, pits, and strength defects in finished products. For raw materials with hygroscopic properties, constant-temperature drying treatment is carried out at 75-85℃ to control the raw material moisture content below 0.03%, completely eliminating bubble defects inside thick-walled containers caused by moisture gasification during high-temperature molding.
According to different product application scenarios, targeted formula mixing is carried out. Industrial chemical drums need to be added with anti-corrosion agents and anti-aging agents to improve chemical resistance and outdoor weather resistance; food-grade water buckets need to adopt pure food-grade raw materials and safe auxiliary additives without any toxic components to meet food contact safety standards. The mixed raw materials are uniformly stirred by a high-speed mixer to ensure stable formula proportion and consistent raw material performance, laying a foundation for stable batch production of the extrusion blow molding machine.
3.2 High-Torque Extrusion Plasticization and Parison Molding
The uniformly mixed raw materials are quantitatively and stably fed into the extruder barrel of the Apollo 30L EBM machine through an automatic feeding system. Under the action of high-torque screw rotation and segmented gradient heating, the raw materials are gradually melted, plasticized, and homogenized to form high-viscosity uniform melt suitable for thick-walled container molding. The high-power extrusion system ensures sufficient melt supply, avoiding insufficient melt filling and incomplete product molding caused by large container volume.
After full plasticization, the melt is extruded downward through the large-caliber precision die head to form a long cylindrical thick-wall parison. The intelligent wall thickness control system dynamically adjusts the thickness of each section of the parison in real time according to the preset product parameter curve, realizing scientific distribution of product wall thickness. This process effectively solves the problem of uneven stress and easy local damage of traditional thick-walled containers, improving the overall structural stability and durability of finished products.
3.3 High-Precision Mold Clamping and High-Pressure Blow Molding
When the parison is extruded to the preset length, the high-rigidity hydraulic mold clamping system quickly and accurately closes the mold and cuts off the excess parison. The stable high mold clamping force prevents mold expansion and parison overflow during high-pressure blow molding, ensuring no flash or burr on the edge of the 30L container. After mold closing, the high-pressure clean air system instantly injects stable compressed air into the parison cavity, pushing the molten thick-wall parison to fully fit the inner wall of the precision mold.
Different from small container blow molding, 30L large-capacity thick-walled containers require longer pressure maintaining and shaping time. The Apollo equipment intelligently adjusts the blowing pressure and pressure maintaining time according to the product wall thickness and raw material characteristics, ensuring that the melt is fully shaped, the internal structure of the container is compact without gaps, and the surface is smooth and flat. The whole blow molding process is automatically controlled by the system with high precision and stable rhythm, ensuring consistent quality of each batch of products.
3.4 Circulating Cooling Shaping and Automatic Demolding
The equipment mold is equipped with a dense and uniform circulating water cooling channel, which realizes three-dimensional balanced cooling of the inner and outer walls of the 30L container. The intelligent temperature control system adjusts the cooling water temperature and circulation speed in real time to ensure synchronous cooling and solidification of all parts of the thick-walled container, avoid internal stress concentration and product deformation caused by uneven cooling, and improve the dimensional stability and structural toughness of finished products.
After the cooling and shaping process is completed, the mold opens automatically, and the finished container is smoothly demolded under the action of the intelligent ejection system. The whole demolding process is stable and efficient, without scratching or deforming the product surface. The automated production mode avoids manual handling errors and improves production efficiency and product appearance consistency.
3.5 Trimming, Inspection and Finished Product Warehousing
The demolded 30L container is automatically trimmed by the supporting trimming device to remove a small amount of residual flash at the mold closing position, ensuring smooth and burr-free product edges. Then the finished products enter the comprehensive quality inspection link, including appearance inspection, dimensional accuracy detection, wall thickness uniformity test, air tightness test, and compression resistance test.
Inspectors check whether the product surface has bubbles, wrinkles, depressions, and color difference, detect whether the caliber, height, and wall thickness meet the standard specifications, and conduct air tightness and pressure resistance tests to ensure no liquid leakage and structural deformation during use. Qualified products are automatically stacked and warehoused, and unqualified products are recycled and reprocessed to ensure that all factory products meet industrial production standards.
