About us

About GreatLight Metal Technology

A 7,600 m² smart manufacturing plant in Dongguan, China — 127 CNC machines, 150 technicians and fifteen years of complex, high-tolerance parts.

Who we are

Fifteen years of precision is the engine

Founded in 2011, GreatLight has focused on precision CNC machining for fifteen years. Technology is our engine — driving the future of high-end manufacturing. From a small machining workshop in Chang’an, Dongguan, we have grown into a 7,600 m² smart manufacturing plant with three wholly-owned plants, 150 professional technicians and 127 precision machines.

That scale exists for one reason: to take the jobs that need engineering judgment — thin walls, exotic alloys, compound surfaces, tight tolerance stacks — and deliver them with paperwork that holds up to an audit.

What we stand for

Three principles, applied daily

Say what is true

Realistic tolerances, honest lead times, and a straight answer when a design or process does not fit. Buyers stay with suppliers they can plan around.

Own the quality chain

Machining, inspection and documentation under one quality system — one standard, no finger-pointing between subcontractors.

Engineer, not just execute

Every quote carries DFM notes. We would rather improve your design margin than quietly ship something that barely works.
