OVERVIEW
The mother facility, where the engineering backbone lives
Dongguan is the technical centre of gravity for the company. It is the site that proves a programme is buildable — at the sample stage and again at the production stage — before the rest of the network ever sees it. Material flow, fixture design, in-process testing, and first-article inspection all originate here.
The campus has grown out from a single registered entity in 2006 to a federated set of specialist subsidiaries: Caimei (assembly + injection), Yuanmei (CNC, injection, assembly · 2019), and Tianmei (metal stamping · 2020). In 2025 we added in-house die-casting and an expanded CNC line — closing the last outsourced gaps in the Dongguan vertical stack.
CAPABILITIES
A full vertical stack, under one operational team
CNC Machining
Mill, lathe, drilling, grinding, and laser-cut. Multi-axis cells from prototype through low-volume production. Tooling fab in-house.
Plastic Injection
Injection moulding with in-house mould design and tool build. All resin families. Co-located with assembly for short-cycle iteration.
Die-Casting
In-house die-casting cell added 2025 — eliminating the last outsourced primary process in the Dongguan stack.
Brazing & Assembly
Sub-assembly, final assembly, ultrasonic welding, riveting, gluing/bonding. Brazing for thermal joints.
In-Process Testing
First-article inspection, dimensional metrology, functional test. Every programme validated here before transfer to a production site.
Finishing & Secondary Ops
Anodising, passivation, pad print, silk screen, laser etch, polishing, sand-blasting, labelling, packaging, calibration.
Engineering Services
Concept design, renderings, 3D CAD solid modelling, material research, FMEA, DFM, material-flow optimisation.
CO-LOCATED LABORATORIES
