Volume and weight
Common cans are 5, 10, 20 and 25 L; the volume and gram weight decide the model and clamping force.

In short
Jerry Can: what to know
Plastic jerry cans for lubricants, chemicals and food liquids are mostly extrusion blow molded from HDPE. Tongda HS, HT and HTS machines cover cans up to 30 L in single- or double-station layouts, with view stripes and multi-layer walls available.
HS and HTS machines are described in the Tongda jerry can range. Multi-layer construction and a view strip can be discussed for the application; mold design and material requirements determine the final arrangement.
Typical products
- Engine oil and lubricant cans
- Agrochemical cans
- Edible oil cans
- Handled cans with view stripes
Materials
- HDPE
- Multi-layer HDPE (barrier layers)
Production process
How the production line works
- Step 01
Prepare the resin
Blow-molding grade resin, masterbatch and regrind are dosed to the product specification.
- Step 02
Extrude the parison
The extruder melts the material and the die head forms a hollow tube of controlled wall thickness.
- Step 03
Close and blow
The mold closes on the parison and compressed air forms the part against the cavity.
- Step 04
Cool and release
The part cools in the mold until it holds its shape, then the mold opens and the part is removed.
- Step 05
Trim and finish
Flash at the neck, handle and base is removed; necks are cut or reamed where required.
- Step 06
Inspect and pack
Weight, dimensions and leak tightness are checked before labeling and packing.
Selection guide
Choosing a machine
Handle and neck
Handle shape and neck position decide the parison placement and the blow-pin arrangement.
Layers and view stripe
Barrier layers or a transparent view stripe change the extruder and die head.
Testing
Plan leak, drop and stacking tests for the filled can with its intended content.

FAQ
Didn't find your answer?
Ask our engineersWhich machine should I use for 20–25 L jerry cans?
The HSII-30L and HWII-30L (formerly HTII-30L) cover cans up to 30 L. For 5–12 L cans, the HSII-5L, HSII-12L and HTII-12L are typical choices.
Single or double station?
A double-station machine increases output for the same can by working with two molds. A single station suits lower volumes or larger molds.
Can the can have a transparent level stripe?
Yes. A view stripe can be added on the die head. It is specified together with the can design.
