30L stacking Barrels Automatic Extrusion Blow Molding Machine
ENJIE Machinery continuous head extrusion blow molding machines adopt the servo motor hydraulic system as standard across the entire series. Compared with traditional systems, the servo motor does not need to run continuously, resulting in significant energy savings, reduced noise, lower oil temperature, and smoother operation. This effectively protects the oil seals and extends the service life of the O-rings and hydraulic components, ensuring long-term durability and reliable performance.

I. Typical Plastic Packaging Products This Machine Can Produce (by Priority)
10L Stackable Pails / Stacking Buckets
Available in single-layer or multi-layer structures (with recycled material in the middle layer).
10L–20L Square Containers / Thin-Wall Canisters / Jerry Cans
For household or industrial chemicals such as detergents and disinfectants, with handles, pouring spouts, or threaded necks.
Engine Oil and Lubricant Containers
Suitable for 10-liter oil cans with volume markings and filling spouts.
Chemical and Agrochemical Packaging
Including pesticide bottles, disinfectant containers, solvent and cleaning chemical containers; typically requiring chemical resistance (HDPE or multi-layer structures).
Food and Liquid Storage & Transportation Containers
Such as large-capacity containers for edible oil or liquid seasonings (food-grade materials and certifications required).
Special Hollow Products
Small water tanks, transport containers, outdoor and gardening products (e.g., sprayer tanks), and certain simple automotive hollow parts.
Summary:
With an 80 mm screw diameter and a 10-liter product focus, this type of blow molding machine is especially suitable for medium-capacity, medium-wall-thickness hollow plastic products, with stackable pails, square containers, chemical containers, and lubricant packaging being the most common applications.

II. Common Raw Materials and Multi-Layer Technology
Common Materials:
HDPE (High-Density Polyethylene) is the most widely used material. LDPE and LLDPE can also be applied when higher flexibility is required.
Multi-Layer Co-Extrusion:
Multi-layer structures can be used to create barrier layers or to incorporate recycled material as a middle layer, reducing material cost while maintaining outer-layer quality.

III. Mold Design and Structural / Functional Considerations
Stacking Structure Design:
Molds must include specially designed bottom and rim features to ensure vertical stacking strength and horizontal stability.
Handles (Integrated or Post-Assembled):
10L containers commonly use reinforced handle bands or one-piece molded handles. Mold design should consider handle positioning and reinforcement ribs.
Neck Finish and Closure Compatibility:
For threaded necks or easy-open lids, the mold design must match the cap mold and downstream filling line. Optional inner-neck forming or secondary threading solutions can be applied.

IV. Output Capacity, Cycle Time, and Process Considerations
Production Capacity and Cycle Time:
For 10L stackable containers, the typical cycle time ranges from several tens of seconds up to about one minute per piece, depending on wall thickness, mold design, cooling efficiency, and deflashing system.
Double-station or dual-head configurations can significantly improve overall productivity. Actual cycle time must be evaluated based on specific molds and cooling conditions.

V. Downstream Equipment and Production Line Integration
Deflashing and Cooling Conveying Systems:
Automatic deflashing units, cooling tables, and conveying/stacking systems help reduce labor requirements and scrap rates.
Inspection, Weighing, and Leak Testing:
Chemical and lubricant containers usually require leak testing, pressure resistance testing, and drop testing.
Printing, Labeling, Coding, and Filling Line Integration:
Finished containers are often connected to automatic labeling or filling lines, especially in the food, chemical, and lubricant industries.

Robot arm take out the barrel and put it on the seperate deflashing machine.

Fully automatic weighing equipment for finished hdpe barrel.

VI. Typical Industrial Application Sectors
Chemicals and Cleaning Products:
Packaging for detergents, disinfectants, cleaning agents, and solvents.
Lubricants and Automotive Aftermarket:
Engine oil, coolant, and other medium-capacity automotive fluid containers.
Construction, Paints, and Adhesives:
Adhesive buckets, paint containers, and construction material pails.
Agriculture and Agrochemicals:
Pesticide containers and large-capacity chemical containers require chemical resistance or multi-layer barrier structures.
Food and Beverage (Specific Applications):
Large-volume packaging for edible oils and liquid seasonings, using food-grade materials and controlled production conditions.

VII. Practical Recommendations for Machine Selection and Purchasing
Confirm the Need for a Multi-Layer Die Head:
Especially if recycled material is planned for middle layers or if barrier properties are required.
Evaluate Control Systems and Energy Consumption:
Servo-hydraulic systems versus conventional hydraulic systems have a significant impact on energy efficiency, noise levels, and maintenance costs. Servo systems are commonly preferred in newer machines.

MACHINE PARAMETER

Spare Parts and Mold Compatibility:
Mold dimensions, opening stroke, and ejection systems must be fully compatible with mold suppliers, whether use single-station or double-station, shuttle or platen structures.
Automation for Deflashing and Stacking:
For high-volume production, a fully automated line with deflashing units and robotic handling
