2026 Top 10 PET Preform Cold Half Mold Suppliers in the world

Introduction to PET Preform Cold Half Mold

PET (Polyethylene Terephthalate) preform cold half molds are crucial components in the manufacturing process of PET preforms. These molds are designed to shape the molten PET material into the desired preform shape during the injection - molding process. The cold half mold, also known as the cavity side mold, works in conjunction with the hot half mold. It provides the external shape of the preform and is responsible for cooling the preform to a solid state quickly and uniformly. High - quality cold half molds are essential for producing preforms with consistent dimensions, good surface finish, and excellent mechanical properties, which are vital for the subsequent blow - molding process to create PET bottles and containers.
