Valve Gate PET Preforms Mould specifications:

I. Off-center Adjustment System

Off-center adjustment system can make the tolerance of preform's wall thickness less than 0.05mm. This system does not affect the lifetime of mold;
II. Self-lock System
International advanced bi-awls fixed orientation self-locked structure has been adopted.
III. Cooling System
All the water Channels in the mold's each inner part, which make the cycle time short enough. And all the cooling channels have been specially treated to prevent them from jam;
IV. Heating System
Double Heating System can ensure that the impact of heating is good and quality control is credible. The Heating Band unit makes nozzles be with invariable temperature. The Heater Unit is used to heat the hot runner plate with long using life and powerful heating capacity.
V. Hot Runner System
The perform mold adopt Pin-valve type Hot Runner System, such hot runner system can reduce mold's each part's wear & tear and maintenance cost, and also save 10%~15% electric energy.
VI. Hydraulic Ejecting System
The perform-doffing success ratio has achieved firm endurance and the whole perform ejecting process will become much quiter
