Compare more than 420 verified UK trade injection moulders on 67 facets of capability.
This is a complete comparison of UK-based trade injection moulders: companies you can send a tool or part design to for production. We cover more than 420 manufacturers, from small shops to large-format volume moulders, across all UK regions. Every one of the more than 8,700 facts on this page is verified and traced back to a source paragraph on the manufacturer's own website. Use the filters to narrow the field by capabilities like press tonnage, cleanroom class, or quality certifications, and directly compare suppliers on 67 distinct facets to build your shortlist.
This lens covers more than 420 verified UK contract injection moulders. Our scope is strictly defined: we list companies that run their own thermoplastic or liquid silicone rubber (LSR) injection moulding presses in-house at a UK site for trade customers. This deliberately excludes brokers, pure toolmakers, and companies that only mould their own proprietary products. The result is a comprehensive list of suppliers you can approach with a part design or existing tooling, with strong concentrations in the South East and West Midlands and verified manufacturers in every region of the UK. The cohort includes everything from high-volume specialists in packaging and consumer goods to certified medical and defence suppliers, and vertically integrated partners offering design, toolmaking, assembly, and fulfilment.
Every capability on cmgraph is grounded in evidence. Each of the more than 8,700 facts is extracted from a manufacturer's public website and linked directly to the source paragraph it came from. This provides a clear audit trail for your sourcing decisions. If a manufacturer disputes any of the 67 facets we track for them, they can flag it for immediate review via a link on their profile. Against this verified data, we compute more than 80 unique differentiation claims, last updated on 2026-08-11. These claims highlight companies with rare capabilities or combinations, such as operating large-format presses over 1,000 tonnes or offering a complete one-roof service from toolroom to finished product fulfilment.
cmgraph is built for impartial procurement. We do not operate a pay-to-play model. Manufacturers cannot pay to improve their ranking, feature more prominently, or remove competitors from the listings. The data you see is the data we find, presented to give you a complete, unbiased view of the UK injection moulding market.
