25 grams 28mm Preform mold

PET preform mold

1.Mold structure

Advanced structure is designed to improve rate of finished products;Two-step double taper locating technology;The each cavity is self locked independently with the core.The off-center adjustment system make the perform thickness error less than 0.05mm.Bottle neck is adopted International Screw thread standard, No cutting of gate to reduce the labor intensity

2. Material of steel

Preform mold Cavity and core use stainless steel 2316 with fine polishing,high hardness to get mold's high precision and good quality. mechanical treatment cavity and core to prolong service life,nitrogen treatment with neck screw.with fitly operation,guarantee Long using life over 2 million shots of injection cycle

3.About gate system

Pin-valve gate,pneumatic drive the nozzle pin simultaneous high speed open and close action. which can effectively control the injection hole open and close actions on each cavity. reliable seal function, smooth moving, low thermal expansion rate ,long using life and also saves electric energy.

4.About hot runner

The hot runner system is designed and made by ourselves, it can achieve ideal and prompt heating effect for preform production ,cavity with lower injection pressure to reduce wear and tear of preform mold parts.we use the double heating system,it has separate temperature control mode ,the heat bar are used to heat the preform mold mainfold plate,small heaters supply the heating temperature for cavity nozzle continuously.

5.Cooling system

Each parts including core ,cavity and valve gate has independently cooling system.

6.special satisfied servive

Each preform mold undergoes strict mold test before delivery.we can provide an experienced team for installation and test as per client's request Standard inter-changeable mold components
