PET Preforms

Mold Features

1.  Valve gate
pin-valve gate ,pneumatic drive the nozzle pin simultaneous high speed open and close action, which can effectively cool 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

2. 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 mould parts

3. heat system
with double heating system, it has separate temperature cool mode ,the heat bar are used to heat hot-runner mainfold , small heaters supply the heating temperature for cavity nozzle continuously.

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

5. heat treatment
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.
