DDW 4CAV Penumatic Self-locking PET Jar Mold with valve pin gate

2millon shots

Along with higher and higher demand of perfect forming, more and more considering of energy saving, Nowadays, cold runner system was eliminated in PET Preforms mould making, usually, Multi-cavity PET Preform mould does use the hot runner system, so the design of hot runner system plays an very important role in PET Preform mould quality guarantee. On the base of foreign advanced techniques, our PET Preforms mold adopt the valve gate(shut-off)  design, in which each cavity has its own heating zone and temperature is measured by independent thermo couple. So some old traditional problems such as left white marks or drawbench on bottom are easily avoided. Mould is produced automatically to save labor force.

Main mould components (core, cavity, screw neck) are made of high-quality mould steel S136 which originates from Sweden (ASSAB). German Vacuum stove is imported for heat treatment of the components, which assures the hardness of components HRC48-HRC50.

In this way, it is no doubt that the mould can be used for 2 million shots without any maintenance, meanwhile, the wall thickness difference between is not more than 0.10mm (length<=100mm), weight difference is less than 0.3g; turning center processes make sure that every mould parts can match very well to ensure mould concentricity; Proper distribution of cooling water system improve productivity effect and molding cycle only takes 15seconds. Utmost 144 cavities in one mould.
