plastic injection moulding preform mold - 72 Cavities PET preform mould
Usually, Multi-cavity pet preform moulddoes use the hot runner system rather than cold runner system, so thedesign of hot runner system plays an important role in mould qualityguarantee. Based on foreign advanced techniques and combined withdomestic clients' demand, we adopt the valve gated design, in which eachcavity has its own heating zone and temperature is measured byindependent thermocouple.(advantages: easily avoid some problems such aswhite or drawbench on bottom). Here, Mould is produced automatically toreduce labor force.
Main mould components (die core, diecavity, screw neck) are made by injection process, and the material ofwhich originates from Sweden high-quality mould steel (HRC 45).In thisway, it is no doubt that the mould can be used for 2 million shotswithout any maintenance, meanwhile, the wall thickness between max. partand min. part is not more than 0.10mm; turning center processes makesure that every parts can match well; proper distribution of coolingwater way improve productivity effect and molding cycle only takes 15seconds( need proper water chiller, bottle design and injectionmachine).
Our mould, designed and developed by ourengineers, is of high precision and long life span without traditionalproblems. In a word, Preform wall thickness is on error of 0.10mm;weight difference is less than 0.3g; 2-5 moulds per minute; 2 millionguarantee; utmost 144 cavities in one mould.

plastic injection moulding preform mold - 72 Cavities PET preform mould
