A 72 Cavities Preform Mold is designed with a highly efficient 6×12 cavity layout, offering excellent balance between high output, mold stability, and maintenance convenience for large-scale PET preform production.
Optimized 6×12 Cavity Arrangement
The cavities in our 72 Cavities Preform Mold are arranged in a precise 6×12 layout, ensuring uniform melt distribution and balanced filling performance across all cavities. This rectangular configuration is widely used for high-speed PET preform production and is compatible with mainstream high-tonnage injection molding machines.
Balanced Hot Runner Manifold Design
The hot runner system of the 72 Cavities Preform Mold is engineered with balanced flow channels to guarantee consistent melt pressure and temperature for every cavity. This helps maintain stable preform weight, reduce variation, and improve overall production efficiency.
High-Performance Gate Inserts
Each cavity is equipped with high-flow gate inserts featuring polished and optimized inlet geometry. This design minimizes pressure loss during injection, improves material flow, and reduces internal stress in the preforms, especially during high-speed cycles.
Fast-Response Valve Gate System
The valve gate system uses centralized pneumatic or hydraulic control with rapid-response actuation to ensure synchronized pin opening and closing across all 72 cavities. This prevents gate drooling, reduces weight deviation, and improves overall molding consistency.
Optional Cavity Pressure Monitoring
For advanced production management, the 72 Cavities Preform Mold can be equipped with individual cavity pressure monitoring ports. Real-time production data allows operators to monitor filling and packing conditions, identify abnormal cavities quickly, and perform predictive maintenance, making the mold suitable for smart factory applications.
