Core turntable type (turntable mold core): Utilizing a rotatable mold core to perform two-stage injection molding on a fixed male mold, this process is simple and easy to operate, suitable for small to medium-sized batches of production. Core-pulling mold design: The material switching is achieved through internal sliders or core-pulling mechanisms within the mold, commonly …
First shot (substrate molding): Using the first injection unit of a two-shot injection molding machine, melt rigid engineering plastics (such as PC, ABS, or PP) and inject them into the first mold cavity to form the substrate part of the product. Mold core rotation or mold switching: After the first shot, the male mold separates …
As industrial manufacturing upgrades towards high precision and intelligence, insert molding technology is also constantly innovating. On the one hand, multi-material and multi-insert composite molding has become mainstream, enabling the one-shot molding of complex products containing multiple different types of inserts. On the other hand, the application of smart inserts is becoming increasingly widespread, embedding …
