Usually, 48 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,
48 cavities preform mould is produced automatically to
reduce labor force. |

48 cavity preform mould
for the preform with PCO 1810 neck, It has has real balanced hot runner
system with valve gate. Equipped with cam roller design. The PET preform
mould is designed with Husky's injection moulding system. The weight of
the preforms is 22g, Cycle time is 26 Sec with general PET screw type
of injection moulding machine. It could reach 13 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 48 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) 48 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 48 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. |
