In short
Milk Bottle: what to know
HDPE dairy and beverage bottles are produced on multi-head extrusion blow molding machines, where the die head, mold, neck trimming and downstream handling work as one line. Tongda’s HTS range includes double-station machines with six- and eight-head configurations described for milk bottles.
Multi-head extrusion supports bottle production. The bottle range includes six- and eight-head applications, with output dependent on bottle weight and the selected configuration. Rotary cutting or deflashing is selected around the neck finish.

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
Neck finishing
Rotary cutting or deflashing is chosen around the neck design and cap fit.
Layer structure
Light-barrier or multi-layer walls change the extruder and die-head configuration.
Line integration
Plan leak testing, conveying and packing with the machine so the line runs as a whole.

FAQ
Didn't find your answer?
Ask our engineersWhich machine is used for small milk bottles?
The HTSII-3L double-station machine is the reference model for milk bottles, with four- or six-head configurations available in the range.
Can the bottle neck be finished on the machine?
Neck finishing such as rotary cutting or deflashing can be integrated. The method is selected for the specific neck finish.
Is the machine suitable for food contact?
Food-contact suitability depends on the resin, the line set-up and your local regulations. Discuss the requirements with the team for your project.
