Lock & Security Components

Custom Lock & Security Hardware Components Change main title to: Lock & Security Components – Precision Manufacturing for Access Control

From pins and cylinders to full lock assemblies – we manufacture the parts that keep people and property secure.

Lock and security components demand precision, durability, and consistency – a failure in any single part can compromise an entire system. For 18+ years, we have manufactured custom lock components for the security industry. From precision pins and tumblers to complete lock housings, our in house processes – CNC machining, high speed stamping, die casting, and injection molding – ensure every part meets your exact specifications. We produce from prototype to high volume runs, with consistent ±0.005mm precision across every batch.

Product Range

Lock Hardware Production Items

Complete Assembly – One Supplier, One Quality Standard

We do more than make lock parts – we assemble them. We can take your components – whether metal, plastic, or a combination – and complete the full assembly in house. This includes integrated assembly, performance testing, and packaging.

For you, this means:

Why Lock Manufacturers Choose Sunlike

Security Grade Precision

Lock mechanisms demand tight tolerances. We hold ±0.005mm precision on critical mating surfaces – ensuring smooth operation and reliable security.

Material Expertise

We work with security grade materials: stainless steel (303, 304, 420), brass (C360), zinc alloy, and engineering plastics – each selected for durability, corrosion resistance, and machinability.

In House Quality Control

Every batch is inspected in our QC lab, with CMM measurement, hardness testing, and salt spray corrosion testing. Full inspection report included with every shipment – so you can verify quality on arrival.

Flexible Production

Support for low volume prototyping and high volume production runs. We can scale with your project – from initial development to full market launch.
