PET hot runner preform mold

Usually, Multi-cavity pet preform mold does use the hot runner system rather than cold runner system, so the design of hot runner system plays an important role in mold quality guarantee. Based on foreign advanced techniques and combined with domestic clients demand, we adopt the valve gated design, in which each cavity has its own heating zone and temperature is measured by independent thermocouple.I.e.,easily avoid some problems such as white or drawbench on bottom). Here, Mould is produced automatically to reduce labor force.Main mold components (die core, die cavity, screw neck) are made by injection process, and the material of which originates from Sweden high-quality mould steel (HRC 45).In this way, it is no doubt that the mold can be used for 2 million shots without any maintenance, meanwhile, the wall thickness between max. part and min. part is not more than 0.10mm; turning center processes make sure that every parts can match well; proper distribution of cooling water way improve productivity effect and molding cycle only takes 15 seconds( need proper water chiller, bottle design and injection machine)Mold is of high precision and long life span without traditional problems.  Preform wall thickness is on error of 0.10mm; weight difference is less than 0.3g; 2-5 moulds per minute; up to 144 cavities in one mould.Main feature:1.control system with simulating stretch testing improve yield rate2.Adopt world advanced dipole taper localization technique, each cavity self-clamp independently, ensure mould concentricity3.standard screw neck, imported nitrided steel with high hardness is of long usage.4.Advanced hot runner design and even heating temperature make sure the high quality of plastic products5.Valve gated type without tail reduces labor force
