Custom Plastic Injection Moulds – Making Your Product Ideas a Reality
Custom injection moulds for automotive, medical, electronics and household applications, built to your specification and shipped worldwide. Explore our automotive, medical, electronics and household moulds.
What We Do
One-Stop Plastic Injection Mould Manufacturing Service
From design review and tool making to moulding, assembly and export shipping – one team for your whole project.
China United Mould Limited designs and builds custom injection moulds and produces moulded plastic parts, die-cast, stamped and CNC machined components in our own plants in Huizhou and Dongguan, China, as we have since 2000. We work from your finished design or join at the concept stage, and take your project from tool fabrication to parts production, decorating and packaging.
With injection machines from 50 to 1300 tons, an in-house tool room and an ISO 9001 quality system, we supply more than 50 companies in over 20 countries.
We mould engineering resins and commodity plastics including PP, ABS, PC, PC/ABS, PA, PMMA, POM and PS, and offer insert moulding, overmoulding, double injection (2K), printing, painting and assembly.
If you are looking for a reliable partner for automotive, medical, electronic or household parts, send us your drawing and our engineers will reply with a quotation and DFM suggestions.
Read MoreMould Design & DFM
A successful production programme starts with the relationship between part design, material, tooling and assembly. Our engineering design and DFM support addresses those decisions together.
Read More- Critical features and mating surfaces
- Material requirements and selection
- Opportunities to simplify production
- Mould flow analysis: filling, gating and potential defects
- Access, fixturing, operation sequence and inspection for machined and fabricated parts
Moulds, Dies & Tooling
Our tooling services cover tooling and mould development, mould manufacturing, and stamping and die-casting die design. We support both the tools used to make a component and the fixtures needed to hold, assemble and inspect it.
Read More- Moulds for plastic and elastomer products
- Stamping dies
- Die-casting tooling
- Mould inserts and replaceable tooling components
- Jigs and production fixtures
Plastic Injection Moulding
Our polymer manufacturing scope supports rigid parts, flexible components, hollow products and combinations of materials. We select the process around the product's geometry, functional requirements and production volume.
Read More- Injection moulding of custom plastic components
- Insert moulding with suitable inserts
- Overmoulding and secondary moulding
- Two-shot and two-material moulding for more than one material or colour
- In-mould labelling and decoration
Rapid Prototyping & 3D Printing
Our 3D printing services support physical design reviews, functional prototypes and suitable production applications. Technology selection depends on material availability, geometry, surface expectations and the purpose of the part, and post-processing and inspection requirements are considered when choosing the route.
Read More- Fused deposition modelling (FDM)
- Stereolithography (SLA) and digital light processing (DLP)
- Selective laser sintering (SLS) and Multi Jet Fusion (MJF)
- PolyJet material jetting
- Selective laser melting (SLM) and direct metal laser sintering (DMLS)

06Sheet Metal & Stamping
Our sheet metal fabrication services cover cut blanks, formed parts, enclosures, brackets and fabricated assemblies, combining processes to suit prototype quantities or repeat production.
Read More
07Surface Finishing & Treatment
We match surface finishing to the part's material, appearance and operating environment. The finish is treated as part of the engineering specification: masking areas, mating surfaces, appearance criteria and any dimensional effect of treatment are defined before processing.

08Assembly & Packaging
Our assembly scope brings manufactured parts and purchased components together into subassemblies and finished products. We organise assembly around the approved bill of materials, component revisions and agreed work instructions, with fit and functional checks at the stages where they are most useful.
Read MoreProfessional Team:
Our engineers design moulds in full 3D with Pro-E, UG, SolidWorks and AutoCAD, review every part for manufacturability and keep you updated through every stage of the project.
Smart Production Line:
An in-house tool room with CNC, EDM, wire cutting and gantry milling, plus 50–1300 ton injection machines with robots, conveyors and assembly lines.
High-Efficiency Mould Delivery:
Moulds and moulding in 3 to 30 days depending on size, prototypes from 1 to 500+ parts in as fast as 7 days, and export packing for worldwide shipping.
Mould Quality Assurance:
An ISO 9001 quality system with CMM inspection, first article inspection and full measurement reports. 90% of our new moulds are approved after one or two trials.
