New Design

For more output request, KPET3200 with Vertical clamping & horizontal injection, adopt patented design:

One extruder screw works with two injection plungers, the PET resin plasticizing, charging never stops by injection/holding process, compared to In-line screw, the drive motor capacity is only 40% but output per hour is the same.

Double shuttle core mold, with Post Mold Cooling system: Double core molds work with one cavity half, save 80% holding/cooling time while molding. Efficient post mold cooling by core mold, preforms keep cooled for one more cycle, ensure the quality and straightness.

Individual setting of injection, with A/ B core molds, can produce two different preform (inner dia, and neck design) at the same time.

Vertical Clamping and upward mold flow the melt material injected from the bottom upward, with balance mold flow and even air vent, preform stress low, not welding line/ bubble.
