Post-processing in MIM refers to the process of finishing and polishing MIM parts. This includes machining, heat treatment, quenching treatment, surface treatment and other processes. Among them, common machining includes milling, drilling and turning. , in order to achieve accurate size and shape requirements. Heat treatment and quenching treatment are used to change the structure and properties of materials and improve their strength and hardness. Finally, surface treatment can improve the surface quality and appearance of parts by polishing and spraying.
MIM parts can be processed into complex shapes by post-processing in MIM, and the requirements of high-precision size and surface finish can be achieved. This makes MIM an advanced manufacturing technology widely used in automobile, electronics, medical devices and other fields.
