AI Technical Summary
The types of chips in the market are complex, and the products made by existing molds cannot fully meet customer needs. The machining cost is high, resulting in poor adaptability of injection molded products.
By combining injection molding with machining, the initial masterbatch injection molding is performed first, and then machining and drilling are performed at the locations where pins need to be installed. This reduces the preparatory work before machining and only performs machining at key locations, thus reducing mold opening costs.
It reduces mold opening costs, improves the adaptability of injection molded products, can adapt to more chip types, and has more stable installation, making it easier to disassemble and replace parts.
