In short
Plastic Toy: what to know
Ocean balls, bowling pins and other hollow toys are extrusion blow molded in multi-cavity molds. Tongda HT and HTS machines are matched to the toy size, cavity count and seam quality required.
The product drawing, material, mold cavities, seams and trimming requirements drive machine selection. Send representative samples and the intended quality checks when discussing a toy project.

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
Seam quality
Clean pinch-off and trimming matter for products handled by children.
Colors
Frequent color changes favor short purge times and simple masterbatch dosing.
Safety requirements
Toy safety testing applies to the finished product and its material.

FAQ
Didn't find your answer?
Ask our engineersWhich machine makes ocean balls?
Machines in the HT and HTS 5 L class, such as the HTS-5L, are typical for small multi-cavity toy production.
Can several colors be produced?
Yes. Color changes are handled with masterbatch dosing; plan purge time into the production schedule.
Are the toys safety certified?
Certification applies to the finished toy and material in your market. The machine is configured to produce the agreed design.
