Usually, 72 cavities preform mold
does use the hot runner system rather than cold runner system, so the design
of hot runner system plays an important role in mold 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,
72 cavities preform mold is produced automatically to reduce
labor force. |

72 cavity preform mold
for the preform with 30/25 neck, equippted with balanced hot runner system
with valve gate. The stripper driven by the cam roller. The weight of
the preforms is 20g, Cycle time is 30 Sec with general PET screw type
of injection molding machine. It could reach 11 Sec with 3 stage post
cooling system. Yichuan provide the 72 cavity PET preform molds for Husky
preform molding system, Netstal PET line.The main components of molds
( die core, die cavity and screw neck) are made by injection process,
which are made of special mold steel ( Germany steel 2316) after preheating
treatment in the original factory in Germany. In this way, the mold 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 72 cavities preform
mold base of 50# steel and sliding block of 718# steel. And the
molds 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 molding cycle only takes 15 seconds( need proper water chiller,
bottle design and injection machine) 72 cavities preform mold, 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 molds per minute; 3 million guarantee; Utmost 72 cavities in one mold. |

1. There are 72 cavities on the mold.
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 mold concentricity. 4. The material of mold die core and die cavity are made of Sweden special mold 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. |
