What Mason and King does

Mason & King Ltd is a family-owned sheet metal fabrication business established in 1954 and headquartered in Leicester, United Kingdom. The company operates from over 70,000 square feet of manufacturing floor space, employs approximately 140 staff, and offers a full design-to-delivery service covering Design for Manufacture, CNC programming, CNC laser cutting and punching, CNC bending, CNC turning, CNC machining, MIG and TIG welding (manual and robotic), finishing (including automated powder coat and wet spray), mechanical and electrical assembly, and UK-wide delivery via an owned vehicle fleet. Technology is built around a fleet of Trumpf CNC lasers and laserpresses (including TC600L and multiple TruLaser 3030 units), Trumpf/Amada/Promecam/Mebusa press brakes with in-process angle measurement, Doosan and Colchester turning centres, Dahlih and Hurco machining centres, and 14 FANUC robotic MIG welding cells plus a FANUC robotic spot welding cell. Quality and traceability are managed through an MRPII system, ISO 9001:2015 certification (held since BS5750 in 1987), mistake-proofing (poke yoke) methodologies, and PPAP reporting capability.

The company's revenue model is sales-led and project-based: custom fabrication work is priced per quote based on component complexity, material specifications, volume, and finishing requirements, with billing handled on a pay-as-you-go basis. GTM motion is direct sales targeting commercial and industrial clients across the UK, supplemented by SEO-optimised location pages for over 30 UK and Irish cities. Customer segments are verticalised across railway, construction and yellow goods, plant machinery, automotive, gaming machines, and healthcare/care bed equipment. Mason & King has remained under family ownership across three generations of the Mason family, with no evidence of external investment, private equity involvement, or public listing. No revenue, funding, or acquisition history is disclosed; all growth has been organic and self-funded, and the company operates exclusively under UK and Ireland geographies.

Products and services

• Design for Manufacture In-house design for manufacture and consultation services using 2D and 3D CAD software (CoCreate, Solid Edge) to optimise product design for fabrication processes. Targeted at industrial and commercial clients needing design support alongside fabrication.
• CNC Programming CNC programming service that converts customer 2D dxf and 3D step model drawings into machine programs, networked directly to fabrication equipment. Targeted at customers supplying digital part files.
• CNC Laser Cutting & Punching CNC laser cutting and punching using Trumpf flat bed lasers, laser presses and multi-tooled rotation punch pressing machinery for sheet metal fabrication. Targeted at industrial customers requiring precision-cut sheet metal components.
• CNC Bending CNC brake press bending using Trumpf, Amada, Promecam and Mebusa machines with in-process angle measurement and bend control for components from 0.8mm to 15mm thick. Targeted at industrial clients needing formed sheet metal parts.
• CNC Turning CNC turning using Doosan and Colchester machines with magazine and hydraulic bar feeds for straight turning, facing, taper turning, profiling, parting, trepanning, external grooving and boring. Targeted at industrial customers needing turned components.
• MIG & TIG Welding Manual and robotic MIG and TIG welding services including projection nut welding, spot welding, CD and drawn arc stud welding, supported by 14 FANUC robot MIG welding cells and a Fanuc robotic spot welding cell. Targeted at industrial clients needing welded assemblies.
• Finishing & Assembly Finishing services including automated track powder coat paint lines, wet spray booth and iron-phosphate pre-treatment, plus mechanical and electrical assembly. Targeted at industrial customers needing finished and assembled products.
