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. Advantage of Valve Gate PET Preforms Mould: l Advanced mould design technology, electric control system with simulating stretch testing improve yield rate. l Adopt top advanced dipole taper localization technique, each cavity self-locks independently and using high precision Japan CNC System. l Ensure low decantation & precision of the product. l In order to improve and achieve high production efficiency, we always design the best cooling system and can match a cooling machine for each mould. l Advanced & accurate valve hot runner & even heating temperature controller, ensure reliability of production, and high transparency &brightness of product. l Mould sliding use copper, Bottle be achieved FOOD SECURITY standard, and mould life guarantee more than 2 million shots. l Valve gated type without tail reduces labor force. |
