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.






SINO mould as the most famous PET preform mould company in CHina, has rather rich PET preform mould manufacturing experience. We are also keeping doing PET preform mould technical renovation.

As we know, the common PET preform mould demolding way is use slider and stripper. And the slider is outer slider type, and then use stripper to ejector the PET preform.
This kind of mould structure make the mould size bigger and customer need to use a big machine to meet the mould running.

It is also difficult for some customer who is new in this area to install the PET preform mould. SINO PK keep researching a best PET preform mould structure for our customer which could reduce investment fund. So far, SINO PK has had a success to improve the PET preform mould outer slider structure to inner slider structure. This kind of improved structure could smaller the mould size, so customer just needs a small size machine to run the mould.
