For manufacturers planning to produce 20L–30L HDPE jerry cans, selecting the right extrusion blow molding machine is an important production decision. The machine should match the container size, product design, material, target output and future product plans. It should also provide stable extrusion, consistent wall thickness, reliable mold clamping and practical operation for daily production.
The lowest initial price is not always the lowest total cost. An unsuitable machine may lead to unstable processing, excessive flash, difficult mold changes, inconsistent product weight or longer commissioning time. A better approach is to evaluate the complete application before choosing the equipment.
Before requesting a quotation, prepare the basic information about the jerry can that you plan to produce:
A 20L jerry can and a 30L jerry can may require different mold dimensions, extrusion capacity, clamping force and process settings. If the same machine will be used for several container sizes, the complete range should be reviewed before the equipment is finalized.
HDPE is widely used for jerry cans because it combines good impact resistance, chemical resistance and processability. However, the material grade, product weight and container structure still influence the required machine configuration.
The extrusion unit, screw design, heating zones and die head should work together to provide stable melt flow. Stable melt flow helps the machine form a consistent parison before the mold closes. If the parison is unstable, the finished container may show uneven wall thickness, inconsistent weight or weak areas around the corners and handle.
For lubricant, detergent, agrochemical or other industrial containers, the buyer should also review the required chemical resistance and finished-container performance. Material selection and machine selection should be evaluated together rather than treated as separate decisions.
The wall thickness of a 20L–30L jerry can is not necessarily uniform across every area. The handle, shoulder, corners and base may require different material distribution to achieve the required strength and shape.
When comparing machines, ask the supplier how the equipment manages:
A sample test based on the actual product drawing is usually more valuable than comparing only nominal machine specifications. It allows the buyer to review the container shape, surface condition, wall thickness distribution and production process before making a final decision.

Automation influences labor requirements, production consistency and operator training. For a factory producing more than one type of jerry can, mold changeover and recipe management can also affect equipment utilization.
A practical equipment review should include:
A clear control interface can help operators manage production parameters more consistently. This is especially important for overseas projects where installation, training and technical communication need to be planned from the beginning.
The machine alone does not determine the final product quality. The mold design, cooling-channel layout, water temperature, water flow and product take-out method all influence the molding cycle.
Before placing an order, the buyer should confirm that the machine can accommodate the intended mold dimensions and movement requirements. The technical review should cover mold thickness, center distance, opening stroke, cooling connections and product removal space.
A well-matched machine and mold combination can help reduce commissioning adjustments and make future product changes easier to manage.
A blow molding project usually involves more than the main machine. Depending on the application, the buyer may also need mold development, auxiliary equipment, installation, commissioning, operator training, spare parts and after-sales support.
When evaluating a supplier, review the following questions:
Dawson Machinery & Mould Group Co., Ltd. states on its public website that its team has more than 20 years of experience in the plastic blow molding machine field. Its public product range includes extrusion blow molding machines, jerry can blow molding machines, plastic blow molding machines, PET-related equipment, molds and plastic auxiliary machines.
For a 20L–30L HDPE jerry can project, Dawson can review the product application, machine configuration and mold requirements as a complete equipment proposal. Customers can send the product drawing, material information and target output for a more focused technical discussion.
