Mold for Plastic container preform

 plastic pet preform mold

1. The mold material must very hard & high polishing.

2. Mold design is the most important,it ensure sprue,molding,surface,ejection & mold life.

3. Quality standard parts to be used for long time.

4. Quality hot runner to be used for reducing cycle times and ensure the surface is good.

5. Our products are widely recognized and trusted by users and can meet continuously developing economic

and social needs.

1.About design
Advanced structure is designed to improve rate of finished products;

Two-step double taper locating technology;

each cavity self locked independently;

off-center adjustment system make the thickness error of perform less then0.01mm.

Bottleneck is adopted International Screw thread standard, No cutting of gate to reduce the labor intensity

--------------------------------------------------------------------------------------------------------

2. Material of steel
cavity and core use imported S136 stainless steel with fine polishing, high hardness to get mold's high precision and good quality.

------------------------------------------------------------------------------------------------------------------------------
3.About gate
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
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 mold parts.reasonable for Husky machine.

-----------------------------------------------------------------------------------------------------------------------------

5.heat system
with double heating system,it has separate temperature control mode ,the heat bar are used to heat the mold mainfold plate,small heaters supply the heating temperature for cavity nozzle continuously.

------------------------------------------------------------------------------------------------------------------------------
oling system
each parts including core ,cavity and valve gate has independently cooling system.

------------------------------------------------------------------------------------------------------------------------------

7.heat treatment
mechanical treatment cavity and core to prolong service life ,nitrogen treatment with neck screw.with fitly operation ,guarantee Long using life over 3.0 million shots of injection cycle

------------------------------------------------------------------------------------------------------------------------------

8.special satisfied servive
each 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
