HPM

What HPM does

HPM Ltd is a privately held UK precision manufacturer headquartered in Sandiacre, Nottingham, operating since approximately 1990. The company runs two complementary moulding platforms: Metal Injection Moulding (MIM), producing complex metal components with >98% density and properties near wrought steel, and Plastic Injection Moulding (PIM), with deep expertise in high-performance polymers including PEEK, PPS, PPSU, LCP, and ETFE. HPM markets itself as the only UK moulder offering a true cradle-to-grave service — spanning design consultation, in-house toolmaking, prototyping, production moulding, sub-assembly, testing, packing, and labelling — all from a single facility. Its quality management system is certified to EN ISO 9002 by BSI, and it routinely operates under NDA for confidential product development.

The company's customer base is concentrated in regulated enterprise end-markets. Named customers include Land Rover, Rolls Royce, Ford, and General Motors in automotive, alongside defence manufacturers, medical device OEMs (sharps containers, heart-surgery components), and emergency equipment producers. Verticals served span aerospace, automotive, defence, electronics, engineering, and medical, with each segment receiving dedicated materials and documentation support (PPAP, FMEA, APQP, full traceability, LOT control). Pricing is quote-based and project-driven, with a separate fixed-price prototyping service; there is no subscription, SaaS, or licensing model.

HPM goes to market exclusively through direct sales, led by named contacts such as Andrew Eyre for new business. Distribution is single-country (United Kingdom), with no resellers or third-party channels. Recent strategic activity includes post-Brexit tooling repatriation into UK facilities, R&D work on HS2 railway signalling products, MIM technology deployment for defence customers that catalysed a 10-component PIM-to-MIM conversion, and a COVID-era pivot into medical device and life-safety components. The company is small (11-50 employees), independent (no disclosed parent, investors, or subsidiaries), and operating without public revenue disclosure.
