8 Cavity Pet Preform Injection Molding
8-Cavity Pet Preform Mould adopts the hot runner system and pin valve gate design to precisely control the flow and filling speed of the plasticized PET material. It effectively eliminates common defects such as preform stringing and bubbles. The molded preform achieves a surface finish of Ra0.2μm, meeting food-grade packaging hygiene standards. The mold is equipped with an independent temperature control system, precisely regulating the temperature of each of the eight cavities to ensure consistent flow of the plasticized material within each cavity, resulting in a finished product dimensional deviation of less than 0.3%. The cavity cooling system utilizes a spiral water channel design, increasing cooling efficiency by 30% and reducing the production cycle time by 1-2 seconds. The mold structure features a double self-locking design, allowing for individual disassembly and replacement of the cavities and cores, facilitating maintenance and reducing subsequent operating costs.

Quality Control
Quality inspectors check machines and molds during production. All products must be inspected and tested before delivery. If necessary, we will provide samples to customers for inspection. We conduct online inspection and final inspection.
1. All processed steel raw materials, hot runner systems and other assembly parts must be inspected after arriving at the factory.
2. All parts must be checked for their origin, identification and every detail during production.
3. All mold processing and assembly processes must be inspected during production.
4. All products must be checked for quality and packaging during final inspection.
