Services
Product Design
Our CAD specialists transform product concepts into manufacturable designs, ensuring technical feasibility and cost efficiency. With 50 years' experience in plastic component design, we optimise for material performance and production efficiency. The team collaborates directly with clients to develop detailed assembly drawings that guide our toolmakers.
Injection Moulding
Precision injection moulding of plastic components using modern machinery and quality materials. Our experts select optimal resins including UV-protected variants, with capability for colour matching and additive incorporation. We handle both small batches and large-scale production runs with consistent quality control.
Rapid Prototyping
Accelerated prototype creation using 3D printing technology and material testing facilities. We validate designs through physical models within days, supported by UV weathering and strength testing equipment. This iterative process ensures functional performance before full production commitment.
Component Assembly
Complete assembly of plastic components with additional fittings and inserts. Our trained operatives use custom jigs to ensure precision in both small and high-volume orders. The process integrates seamlessly with our design and manufacturing capabilities for complete quality control.
Surface Finishing
Specialist surface treatments including electroplating for chrome, nickel, or gold finishes. We maintain material integrity while achieving decorative and functional surface properties. This service combines weight reduction benefits with the aesthetic qualities of metal finishes.
