Introduction:
We specialize in manufacturing precision metal parts for the lock industry, including mechanical locks, smart locks, padlocks, and access control systems. Using Powder Metallurgy (PM), Metal Injection Molding (MIM), and CNC machining, we produce high-strength components with excellent wear resistance and dimensional stability.

Key Components We Supply:

• Lock Cores & Plug Bodies – High-precision MIM or PM parts for cylinder locks

• Rotors & Cam Discs – For deadbolts, lever locks, and latch systems

• Anti-drill Pins & Tumblers – Hardened components to enhance security

• Internal Gears & Levers – For motorized smart locks and digital mechanisms

• Housing Shells & Brackets – CNC-machined or sintered casings for durability

Material Options:

• 316L / 17-4PH Stainless Steel

• Iron-Copper Alloy

• Zinc-based PM blends

• Tool Steel with heat treatment

Surface Finishes Available:

• Black oxide / Nickel plating

• PVD coating for premium appearance

• Polishing / Tumbling

• Laser engraving for branding

Why Choose Powder Metallurgy for Lock Components?
