Who we are
OEM & ODM manufacturing – custom tooling, components and finished assemblies
China United Mould is an injection mould (injection mold) factory in Huizhou and Dongguan, Guangdong, China, building custom moulds and moulded parts for customers in more than 20 countries.
Established in 2000, China United Mould Limited (CNM) helps product companies turn engineering requirements into manufactured parts and assemblies, from our own plants in Huizhou and Dongguan, China. Our OEM and ODM services bring product development, mould and tool making, component production, finishing, assembly and packaging into one coordinated manufacturing programme.
For OEM projects we work from your drawings, material specifications and approved samples. For ODM projects we support the development of the product itself, from design refinement and prototype evaluation through tooling and production preparation. You can engage us for an individual component, a dedicated tool or a complete assembly.

How we work
Every process in-house, one responsible team
Mould and tool making, moulding, machining, casting, sheet metal, finishing and assembly are all carried out in our own plants. Each project has an agreed production route, defined acceptance criteria and one team responsible from start to finish – so you deal with one manufacturer instead of many suppliers.
We manage the sequence from engineering review to tooling, production, finishing, assembly and packaging, keeping technical decisions connected to cost and delivery requirements.
Industries we serve
- Automotive parts
- Electrical & electronics
- Medical & industrial
- Consumer and professional products
- Home & office products
- Building, construction and transportation
- Furniture, furnishings and fittings
