PET Preform Mold

Features1.  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 energy2. 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 parts3. 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.Mold DescriptionPneumatic, pin-valve gate, shut-off, free-cut,  PET preform mold with hot runner.Cavity quantities6 and 72 cavitiesMain mold baseP20 steel (Nitrogen treatment, HRC 28-32 degree)Core (punch) and cavityS136  (Vacuum quench treatment, HRC 43-52 degree)Screw neck (lip)S136Heating plateH13 steel , Chinese standard manifold.Heating ringROTFIL from Italy.Temperature controllerPID voltage temperature controllerPreform mold configurationAdopted European moldstructure; PET materials go into nozzle tip straightly to improve mold cycle time.Cooling system on cavity, core. If you require,we also design the cooling system on neck (slip).Preforms drop through injection machine central ejector automaticallyThe controller heat Individual cavities, runner and sprue.One Temperature zone control one point temperature.Double-locked, inter-changeable mold components;Usage life(guarantee)2,000,000 shotsWarranty Period2 years
