Miles Platts

What Miles Platts does

Miles Platts (legal name Miles Platts Ltd.) is a UK-based, privately held precision injection moulding company founded in 1971 and headquartered at Blaby Industrial Park, Leicester. The company designs and manufactures electro-technical moulded components — principally coil bobbins, solenoid bobbins, EV motor bobbins, stator end caps, busbar covers, and electrical insulation parts — in glass-filled and flame-retardant high-performance engineering polymers (PA6, PA66, PA46, PPA, PET, LCP, PPS, PBT, PEEK). Its technical moat centres on proprietary Perfect Layer / Orthocyclic Winding bobbin designs that achieve up to 90% coil fill factor versus 65-70% for random wound coils, micro-moulding of sub-0.05g components at ±0.001 inch tolerance, and computer-controlled micro-pinning with HD imaging and 100% automated inspection at up to 3,600 parts per hour. Operationally, the company runs 20+ injection moulding machines (25-200 tonne clamp force) on a 24-hour schedule, producing 8 million+ units per month with in-house mould tools rated for 500,000+ cycles, supported by an integrated toolroom with CNC machining, EDM, and wire erosion capabilities.

Miles Platts commercialises through two product streams: a standard catalogue of ferrite core, metric and inch lamination, AMCC, toroid, and terminal/accessory bobbins; and bespoke custom-designed components for transformer, automotive, medical, audio, alternative energy, and motor manufacturers. Revenue is generated via quote-based pricing on direct sales and through a network of 11 regional distributors spanning 30+ countries across Europe, North America, Asia Pacific, the Middle East, and Africa. The customer base includes Porsche, Ford, Mercedes-Benz, Valeo, Ogura, wind turbine generator manufacturers, smart electricity meter OEMs, and medical equipment providers. Pricing is quote-based on custom moulded parts, with multi-year enterprise contracts; UL QMMY2 moulder certification, BS EN ISO 9001:2015, RoHS, and REACH compliance support qualification in safety-critical applications.

The business is family-influenced, with second-generation ownership via David Platts, who transitioned in May 2025 from a 25-year tenure as Managing Director to a CEO and Strategic Advisor role alongside newly appointed Managing Director Simon Shenton, an external hire with prior experience scaling a global precision manufacturer. Reported headcount is in the 51-100 band, with no external institutional investment, parent company, or M&A activity disclosed.

Core offering

Miles Platts designs and manufactures precision injection-moulded electro-technical components, primarily coil bobbins and insulating parts, using high-performance engineering polymers including glass-filled and flame-retardant grades. The company sells both a standard catalogue product line (bobbin ranges for ferrite cores, inch and metric laminations, AMCC cores, terminals, wire pins, clips and accessories) and bespoke custom-designed components for transformer, automotive, medical, audio, and renewable energy applications. Operations include in-house tool design and manufacture, mould flow analysis, precision injection moulding across 25 to 200 tonne machines, micro-moulding, micro-pinning, and terminal insertion.

Product overview

Miles Platts is a designer and manufacturer of precision technical mouldings serving the electro-technical industry since 1971. The company's portfolio centers on precision injection-moulded coil bobbins and electro-technical components, offered through two primary channels: a comprehensive standard product line spanning ferrite core bobbins (RM, PQ, ETD, EC, EE, EFD, EP, E, U ranges), metric and inch lamination bobbins (M, N, E, A, K, L, S ranges), AMCC coil bobbins, toroid mounts, terminals (pressed terminals and wire pins), clips and accessories, and the newly introduced pot core bobbins; and custom-designed components including bespoke solenoid bobbins, EV motor bobbins, stator end caps, busbar covers, and electrical insulation components. These products are supported by a suite of manufacturing capabilities including micro-moulding, micro-pinning, precision injection moulding, in-house tool design and manufacture, component design services, polymer selection expertise, terminal insertion, tooling transfer, and perfect layer/orthocyclic winding solutions. The company operates from UK facilities with global distribution across 30+ countries.
