Because MIM's manufacturing process can help consumers customize small and complex geometric metal parts, it solves the difficulty of forming complex parts with traditional processes such as machining. At present, this has become a high-stability, high-strength, and high-efficiency process. The modern near-formed metal manufacturing process is very suitable for the mass production of small and precise products. Its application fields are also very wide, such as: mobile phone card slot, lens frame, smart flip phone hinge, smart electronic lock cylinder, smart home equipment and other electronic products.
