MIM Door Lock Components are precision metal parts manufactured through Metal Injection Molding technology for residential, commercial, and industrial locking systems. MIM enables the cost-effective production of complex lock mechanisms with excellent dimensional accuracy, wear resistance, and high mechanical strength.
Typical applications include mortise locks, deadbolt locks, smart locks, lever handle locks, and security locking systems.

Metal Injection Molding is ideal for door lock components requiring:
-Complex geometries
-Tight tolerances
-High wear resistance
-High-volume production
-Consistent mechanical properties
-Reduced machining operations
Compared with conventional machining and die casting, MIM significantly reduces manufacturing costs while enabling intricate lock designs."
