Sigma Manufacturing Solutions

About us

Global Series Manufacturing for Complex Critical Metal Parts & Assemblies

Sigma helps OEMs and Tier 1 manufacturers develop, industrialize and source complex metal components and assemblies through a managed global manufacturing network.

Operating across the mobility, energy and industrial sectors, we provide access to specialist manufacturing capabilities including castings, forgings, fabrication, precision machining and assembly, supported by end-to-end programme management, quality assurance and supply chain expertise.

Unlike traditional sourcing companies or individual manufacturers, Sigma acts as a single accountable partner throughout the product lifecycle. From early-stage design support and Design for Manufacture (DFM) through to supplier selection, industrialization, production launch and series supply, we simplify the process of bringing complex components to market.

Our managed manufacturing network spans India, South Korea and Europe, providing customers with access to world-class manufacturing capability, competitive global sourcing solutions, and the flexibility to optimize cost, capacity and supply chain resilience.

Supported by UK-based programme management and local technical and quality teams within our manufacturing regions, we ensure supplier performance, product quality and programme delivery are managed proactively at every stage.

How We Work

We combine the capabilities of a global manufacturing network with the accountability of a single supplier relationship.
Rather than managing multiple manufacturers, contracts and supply chains, customers work with one partner responsible for coordinating every aspect of delivery, from technical feasibility and supplier selection through to quality, logistics and ongoing production support. This approach reduces supply chain complexity while improving visibility, accountability and programme control.
