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

48 cavity preform mold
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
mold is designed with Husky's injection molding system. The weight of
the preforms is 22g, Cycle time is 26 Sec with general PET screw type
of injection molding machine. It could reach 13 Sec with 3 stage post
cooling system.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 48 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) 48 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 48 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. |
