Casting & Forging
High-specification cast and forged components for mobility, energy, Industrial and aerospace applications, from precision housings to large, robust enclosures.
Precision and Scale
Sigma delivers a full range of casting and forging solutions, including PMDC, HPDC, LPDC, and precision sand casting. We produce both large components, such as battery enclosures for off-highway applications, and smaller, high-precision housings for EV motors and aerospace assemblies.
Programmes benefit from early technical alignment, prototyping support, and scalable production through our manufacturing partners in Korea and India, ensuring consistent quality, performance, and delivery across every volume and specification.
Quality and Compliance
Every component is supported by rigorous quality systems, including IATF 16949, ISO 9001, and AS9100 where applicable. Additional processes include precision machining and finishing to achieve exacting tolerances, giving procurement teams confidence in both accuracy and repeatability.
