72 Cavity Preform Mold

This is a 72 cavity preform mold, which is commonly used in the injection molding process of plastic bottle production. This kind of mold can form 72 preforms at one time, effectively improving production efficiency. There are multiple fine holes and complex pipeline structures on the mold. The holes are used for preform molding, and the pipelines are part of the cooling system or the hot runner system. The former helps the plastic cool and set quickly, while the latter is used to transport high-temperature plastic melt. The red brackets at the bottom of the mold play a supporting and stabilizing role, and various interfaces on the mold are used to connect external equipment such as injection molding machines and cooling devices to ensure the normal operation of the mold.
