48cavities preform mould
1. Usually, Multi-cavity pet preform mould does usethe hot runner system rather than cold runner system, so the designof hot runnersystem plays an important role in mould qualityguarantee. based on foreign advanced techniques and combined withdomestic clients demand, we adopt the valve gated design, in whicheach cavity has its own heating zone and temperature is measured byindependent thermocouple. (advantages: Easily avoid some problemssuch as white or draw bench on bottom). Here, Mould is producedautomatically to reduce labor force.
Main mould components (die core, die cavity, screw neck) are madeby injection process, and the material of which originates fromSweden high-quality mouldsteel (HRC 45). In this way, it is no doubt thatthe mould can be used for 2 million shots without any maintenance,meanwhile, the wall thickness between max. Part and min. Part isnot more than 0.10mm; Turning center processes make sure that everyparts can match well; Proper distribution of cooling water wayimprove productivity effect and molding cycle only takes 15seconds( need proper water chiller, bottle design and injectionmachine)
2. Our mould, designed and developed by our engineers, is of highprecision and long life span without traditional problems. In aword, Preform wall thickness is on error of 0.10mm; Weight difference is lessthan 0.3G; 2-5 moulds per minute; Utmost 144 cavities in onemould.
Main feature:
Cavity from 1 up to144.
Control system with simulating stretch testing improve rate ofproduction.
3. Adopt world advanced dipole taper localization technique, eachcavity self-clamp independently, ensure mould concentrically.
4. Material of mould die core and die cavity are made of Swedenspecial mould steel.
5. Standard screw neck, imported nitride steel with high hardnessis of long usage.
6. Advanced hot runner design and even heating temperature makesure the high quality of plastic products.
7. Valve gated type without tail reduces labor force.
8. At least 2 million shots guarantee.
