Who we are
China United Mould: tooling and metal parts since 2000
China United Mould Limited (CNM) was founded in 2000 and runs two plants in Guangdong, China, one in Huizhou and one in Dongguan. Our work is managed under an ISO 9001 quality management system. The tool room has CNC machining, EDM and wire cutting, so the dies for our castings are designed and built in house.
This website covers our die casting work: aluminum and zinc die castings, die casting dies, gravity and sand castings, and the trimming, machining and finishing done after casting. For plastic injection molds see www.chinaunitedmould.com; for BMC and SMC thermoset parts see www.bmcmolds.com.
What we handle on a die casting project
- DFM review of the part before die design
- Die design and die making in our own tool room
- Casting trials and first article samples with a dimensional report
- Trimming, deburring and CNC machining
- Heat treatment and surface finishing to your specification
- Final inspection and export packing
How we work
What we need from you, and what you get back
Most open points on a casting can be settled on paper: draft, wall thickness, where porosity is acceptable, which faces are machined and which datums the machinist will use. We go through them with you before the die design is released, because changing hardened steel later costs time and money.
For a quotation we need the 3D model (STEP or IGES) and the 2D drawing, the alloy or the properties you need, the annual volume, and any requirements for machining, finishing, leak testing or X-ray inspection. You get DFM comments back together with the price of the die and the parts.
