28mm-38mm Plastic Pet Bottle Preform Mold
Our company can make 12-48 CAV. PET Preform mould with hot runner system. Using point to point temperature control, it is easier to adjust every cavity of the temperature of the mould. The quality of the preform is the same like Canada quality. The design of the preform also different that make your capacity increase.
28mm-38mm Plastic Pet Bottle Preform Mold - HOT RUNNER SYSTEM
A). Hot runner employs PID controlling system which features automatic compensation and automatic protection, and contributes to the prolongation of lifetime of electric heater;
B). The precision of temperature controlling falling within 1 degree which ensures to avoid plastic in the hot runner being burnt, resulting in a yield of up to 99% and more;
C). Ultra nozzles are designed to be maintenance-friendly. Nozzle tip inserts, heaters, tip insulator, and thermocouples are easily accessible an can be replaced while the hot runner is mounted in the machine, which minimizes down-time and reduces maintenance cost.
Core and cavity in mould are top materials. All the parts are processed on CNC machine tool with high precision, especially the plate, the tolerance is less than 0.05mm. And all parts are treated by heat treatment strictly. To ensure their intension and life time good enough. After the treatment, the intensive neck ring and core hardness can be HRC48~52, the hardness of cavity can be HRC44-48.
