What CNC Speedwell does

CNC Speedwell is a UK-based CNC machining company and wholly owned subsidiary of Castings PLC, specialising in the production and prototype machining of cast iron, aluminium, and steel parts up to 600mm square. Operating from a consolidated 78,000 square metre site in Brownhills, West Midlands, the company runs 127 CNC machines with 226 spindles across two machine shops on a three-shift system, delivering more than 24,000 spindle hours per week of capacity and employing over 350 people. It serves both as a Tier 2 supplier machining chassis and powertrain components for Castings PLC foundries' commercial vehicle customers, and as a direct Tier 1 supplier to automotive manufacturers, with customers in Europe and the USA.

The service portfolio is vertically integrated beyond core machining. It includes industrial washing via 35 Mecwash and Technowash systems with an onsite testing laboratory, finishing, assembly (including welded assembly under licence and integration of bought-out components such as ball joints, bushes, pins, O-rings, seals and wet silicon), warehousing, and a conditioned metrology room equipped with Hexagon PC DMIS, Aberlink Xtreme, Faro Measuring Arm, Keyence IM7000, and Mitutoyo surface finish and form tracing equipment. Quality assurance follows Automotive Core Tools — APQP, PPAP, FMEA, SPC and MSA — and the operation is certified to ISO 9001, EMS 14001 and IATF 16949.

Revenue is generated through custom quotation-based pricing on multi-year B2B contracts, with no public pricing disclosed and no minimum or maximum quantity restrictions within the 600mm square envelope. Reported turnover of £22.5M for the financial year ending 31 March 2022 (within the Castings PLC Group's £149M total turnover) reflects its position as the Group's machining and assembly division rather than a standalone growth-stage business. Marketing is essentially direct, relying on customer relationships and the Castings PLC corporate channel, with no significant outbound digital marketing presence.
