12 cavities pet preform mould,valve gate hot runner. Generally speaking, the production capacity is not very large. The minimum number of cavities of the lightweight PET preform mold we choose is: 8 cavities. Compared with 8 cavities, the 12-cavity PET preform mold is not that big, and it can use the same size injection molding machine. The arrangement of the 12-cavity plastic PET preform mold is: 6*2, the width is the same as the 8-cavity PET preform mold, but the production capacity may be higher. So I recommend you to choose 12 cavities instead of 8-cavity PET preform mold.

Main Parts of Bottle Preform Mould:
1. The core mold parts are made of S136 high-strength stainless steel, and the hardness after processing can reach HRC49-51 degrees, ensuring the service life of the mold.
2. The core mold adopts a taper locking design, which is convenient for injection molding exhaust and ensures that there is no shortage of materials;
3. The neck ring adopts a double-taper locking design, which is accurate in positioning, more durable, and can withstand high-pressure injection molding;
4. The cavity water channel adopts a spiral independent fast circulation structure to ensure a fast cycle time;
1.Hot runner electrical components and core parts are imported from Germany or Canada and are interchangeable with internationally renowned brands.
2.Parts are interchangeable;
3.Double-pin insertion temperature control sensor, maintenance-free design, more accurate detection of hot runner plate temperature.
