hot runner PET preform mould, preform mold

1.design of the preform mould
Advanced structure is designed to improve rate of finished products Two-step dual taper locating technology; each cavity self locked independently; off-center adjustment system make the thickness error of perform less then0.05mm. Bottleneck is adopted International Screw thread standard, No cutting of gate is employed to reduce the labor intensity

2. Material of steel for the preform mould
cavity and core with imported 1.2316 stainless steel with fine polishing, high hardness and anticorrosion to get mold's high precision and good quality.
3.gate of the preform mould
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.hot runner for the preform mould
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 mould parts.
5.heat system for the preform mould
with double heating system,it has separate temperature control mode ,the heat bar are used to heat the mould mainfold plate,small heaters supply the heating temperature for cavity nozzle continuously.
6.cooling system for the preform mouild
each parts including core ,cavity and valve gate has independently cooling system.
7.heat treatment for the preform mould
mechanical treatment cavity and core to prolong service life ,nitrogen treatment with neck screw.with fitly operation ,guarantee Long using life over 2.0 million times of injection cycle
8.quality controling for the preform mould
each mould undergoes strict mould test before delivery.we can provide an experienced team for installation and test as per client's request Standard inter-changeable mould components
