ZQ 32,48,72,96 cavities PET preform injection molding systems uses a new part cooling and handling system, which features:
1.  Cooling on the inner surface of the preform without using compressed air, unlike most post-mold cooling systems which only cool the outer surface
2.  Optimized cycle utilization — being mounted on the moving platen, the cooling system remains active for up to 85% of the overall cycle.

PET preform injection molding systems are available from 280 to 500 tonnes (2800 to 5000 kN) and up to 96 cavities.

Usually, Multi-cavity pet preform mould does use the hot runner system rather than cold runner system, so the design of hot runner system plays an important role in mould 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.(advantages: easily avoid some problems such as white or drawbench on bottom).

Here, Mould is produced automatically to reduce labor force.
