The metal injection molding process produces high-quality finished metal parts for door locks by molding metal alloy powder into plastic. Metal injection molding parts combine two proven processes: plastic injection molding and powder metallurgy. The process shapes metal alloys like plastic.
The MIM process is ideal for producing relatively small (1 to 50 grams), complex-shaped metal parts with tight tolerances, high strength, and good surface finish requirements. Therefore, various lock components require unique geometric features. Before the discovery of the MIM process, most smart door lock manufacturers purchased many of these parts as machined parts or investment castings.

MIM has been widely used to manufacture door lock parts, which were originally produced through an investment casting process. The main components of MIM-lock parts include cylinders, bolts, latches, and plates.

The advantages of MIM over investment casting are as follows:
1、MIM can produce thinner wall sections and sharper cutting points
2、MIM produces a better surface finish
3、MIM is more suitable for small diameter blind holes and through holes
4、MIM greatly reduces the requirements for finishing
5、MIM produces a large number of small parts at a lower cost and faster delivery time
