Expanding into the sector, bringing decades of high-performance engineering experience
We support defence and aerospace clients with the design, development and manufacture of critical plastic components and assemblies.
We are a full-service engineering and manufacturing partner with in-house design, prototyping, tool making, injection moulding, assembly and painting. This turn-key capability allows us to respond quickly to the demands of Defence and Aerospace projects.
We produce everything from small, precision parts to large complex components — including twin-shot moulding for multi-material assemblies and high-spec surface finishes. Our flexible automation systems are ideal for high-performance sectors, with QA processes and paint lines that consistently meet OEM standards.
As the UK’s largest independent plastics manufacturer, WHS Plastics offers unrivalled scale, scope and flexibility. We operate across multiple secure sites with dedicated areas for defence-specific projects. Our in-house project teams and programme managers ensure seamless delivery.
We work at both high and low volumes, adapting to evolving requirements with speed and care. For defence clients, that means fewer handovers, tighter control, and confidence in a supplier who understands the stakes.
