What Wallwork Group does

Wallwork Group is a privately held, family-owned metallurgical processing services company founded in 1959, operating from four UK manufacturing sites (Bury/Manchester, Cambridge, Birmingham, Newcastle) plus two transport hubs (Yeovil, Crawley). The company provides thermal processing services — heat treatment, nitriding, vacuum brazing, hot isostatic pressing (HIP), and PVD coatings — to engineering manufacturers in aerospace, motorsport, medical, automotive, additive manufacturing and industrial tooling. It self-describes as the largest independent heat treatment and coatings company in the UK, offering 117+ distinct thermal processes, with 29 vacuum furnaces, 10 gas nitride furnaces, and 6 plasma nitriders, plus a 50+ vehicle commercial transport fleet that handles nationwide collection and delivery. Major customers are primarily in aerospace, with additional high-value work in F1 motorsport, medical implants, and the post-processing of additively manufactured metal parts.

The company's revenue model is project-based B2B services: customers submit components for processing under quotes priced by complexity, weight, material and process specification, with no subscription or recurring pricing. Distribution is direct enterprise field sales supported by a customer portal and mobile app, plus extensive participation in industry exhibitions (Farnborough, Paris Airshow, DSEI, Formnext). The technical backbone is built on partnerships with Quintus Technologies (HIP equipment, with two Quintus URC units now installed), Rübig (plasma nitriding furnaces), and an exclusive commercialisation agreement with Fintek for the proprietary PALMS electrochemical plasma surface-finishing process developed in-house. Wallwork holds NADCAP Gold Merit Status, AS/EN9100 and ITAR certifications, and has invested £20 million+ in HIP capacity alone over 2023-2025 to serve growing demand in additive manufacturing densification and aerospace component production.

Recent strategic posture is defined by aggressive organic capital investment: a £10M HIP Centre opened in September 2023, a second HIP accelerated by two years and operational by November 2025, a £650K plasma nitriding expansion in 2024, a tenth gas nitride furnace at Birmingham in April 2025, a UR Cobot deployed for vacuum brazing in August 2025, and a dedicated vacuum carburise furnace installed in 2024 to serve motorsport demand. The company is also pursuing geographic expansion through exhibition presence in Ireland and growing international order flow from France, Germany, Italy, Turkey and India, while maintaining its core identity as a UK-based, family-controlled specialist serving regulated, certification-heavy industrial end markets.

Partnerships

Four partnerships are on record, tiered core, secondary and minor.

• FintekcoreStrategic or Co-development Partner · 30 August 2024Wallwork Group entered into an exclusive partnership with Fintek for the PALMS (Plasma Additive Layer Manufacture Smoothing) technology. PALMS was developed at Wallwork's Cambridge R&D centre and Manchester machine build division. The exclusive agreement grants Fintek rights to offer PALMS as a subcontract service and for machine sales, enhancing Fintek's surface finishing capabilities. PALMS is an electrochemical plasma process for reducing surface roughness of 3D printed metal parts, providing an environmentally friendly alternative to traditional surface finishing methods with no toxic waste produced.
• Quintus TechnologiescoreTechnology or IntegrationQuintus Technologies is the global leader in high pressure technology and has supplied Wallwork's hot isostatic pressing systems. Wallwork has invested £20 million in two Quintus HIP units (QIH173L type) for the Wallwork HIP Centre at Bury. Quintus Technologies is currently completing installation and commissioning of HIP units. The relationship includes ongoing technical support as Wallwork continues to evaluate investment in additional HIP capacity. Quintus was the platinum sponsor of HIP 2025 conference where Wallwork was a gold sponsor.
• RübigsecondaryTechnology or IntegrationWallwork Group purchased two new Rübig Micropuls Everest plasma nitriding furnaces for their Cambridge plasma nitriding centre in a £650K investment. Rübig is the manufacturer of the plasma nitriding equipment used by Wallwork. The furnaces feature three heating and cooling zones, precise component temperature monitoring, and blast chillers for reduced process times.
• Sheffield Hallam UniversityminorOthersTwo placement students from Sheffield Hallam University (Mya Turner, marketing intern, and Adam Griffin, engineering student) conducted an analysis of Wallwork's transportation operations, calculating CO2 emission savings from the company's integrated logistics model. This was an academic partnership resulting in published sustainability data for Wallwork's customer portal.
