Usually, 8 cavities 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,
8 cavities preform mould is produced automatically to reduce
labor force. |

8 cavity preform mould
for the preform with PCO 1810 neck. The weight of the preforms is 21g,
Cycle time is 20 Sec with general PET screw type of injection moulding
machine. It could reach 10 Sec with 3 stage post cooling system.The main
components of moulds ( die core, die cavity and screw neck) are made by
injection process, which are made of special mould steel ( Germany steel
2316) after preheating treatment in the original factory in Germany. In
this way, the mould with long life service and high quality can be used
for 3 million shots without any maintenance, meanwhile, the wall thickness
between max. Parts and min. Part is not more than 0.05mm. We adopt 8
cavities preform mould base of 50# steel and sliding block of
718# steel. And the moulds equipped with imported components including
high-qualitied lubricating copper plate, Germany heaters HOTSET, Germany
standard PID temperature controller. Moreover, turning center processes
make sure that every parts can match well; Proper distribution of cooling
water way improve productivity effect and moulding cycle only takes 15
seconds( need proper water chiller, bottle design and injection machine)
8 cavities preform mould, designed and developed by our engineers, is of high precision and long life span without traditional problems. In a word, Preform wall thickness is on error of 0.05mm; Weight difference is less than 0.3g; 2-5 moulds per minute; 3 million guarantee; Utmost 72 cavities in one mould. |

1. There are 8 cavities on the mould.
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 3 million guarantee. |
