plastic preform injection mold - 24 Cavities PET preform mould
Usually, Multi-cavity pet preform moulddoes use the hotrunner system rather than cold runner system, so thedesign of hotrunner system plays an important role in mould qualityguarantee. Basedon foreign advanced techniques and combined withdomestic clients'demand, we adopt the valve gated design, in which eachcavity has its ownheating zone and temperature is measured byindependentthermocouple.(advantages: easily avoid some problems such aswhite ordrawbench on bottom). Here, Mould is produced automatically toreducelabor force.

Main mould components (die core, diecavity, screw neck) are made byinjection process, and the material ofwhich originates from Swedenhigh-quality mould steel (HRC 45).In thisway, it is no doubt that themould can be used for 2 million shotswithout any maintenance, meanwhile,the wall thickness between max. partand min. part is not more than0.10mm; turning center processes makesure that every parts can matchwell; proper distribution of coolingwater way improve productivityeffect and molding cycle only takes 15seconds( need proper waterchiller, bottle design and injectionmachine).

Our mould, designed and developed by ourengineers, is of highprecision and long life span without traditionalproblems. In a word,Preform wall thickness is on error of 0.10mm;weight difference is lessthan 0.3g; 2-5 moulds per minute; 2 millionguarantee; utmost 144cavities in one mould.

plastic preform injection mold - 24 Cavities PET preform mould
Main feature:
1.Mold cavity from 1 up to 144.
2.Electric control system with simulating stretch testing improve yield rate.
3.Adopt world advanced dipole taper localization technique, each cavity self-clamp independently, ensure mould concentricity.
4.The material of mould die core and die cavity are made of Sweden special mould steel.
5.International standard screw neck, imported nitrided steel with high hardness is of long usage.
6.Advanced hot runner design and even heating temperature make sure the high quality of plastic products.
7.Valve gated type without tail reduces labor force.
8.At least 2 million guarantee.
