SINO PK is very famouse in plastic package mould industry,we have successfully made many PET preform mould, cap mould, flip top mould and other packing mould.

Regarding the PET preform mould, we will make point gate, pin vavle gate etc.
But usually we will use pin valve gate system, it is very popular in current PET preform mould manufacturing.
Because the pin vavle gate will leave a very small gate mark and no more material overflow in the injection process.

Below pictures are the pin vavle gate system basic structure, which are self-explaining.
