1. Valve 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
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 mold parts
3. heat system With
double heating system, it has separate temperature control mode ,the
heat bar are used to heat hot-runner main fold , 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.
