Our Injection Moulding Process – Explained
1. Design & Tooling
We work with you to develop or optimise a CAD model that’s suitable for injection moulding. Our engineers advise on wall thickness, draft angles, and material selection for optimal performance and cost efficiency.
2. Tooling Manufacture
We create high-precision steel or aluminium moulds tailored to your design, with options for soft tooling, prototype tools, or long-life production moulds.
3. Moulding & Quality Control
Molten thermoplastic is injected into the mould under pressure. Once cooled and solidified, each part is ejected, checked, and batch-verified for dimensional accuracy, fit, and finish.
4. Finishing, Assembly & Delivery
We offer secondary operations such as trimming, ultrasonic welding, and kitting, as well as custom packaging. Your parts arrive ready to use or assemble.
Common Applications
Our injection moulded parts are used across:
- Automotive clips, housings, and bezels.
- Medical device shells and connectors.
- Electrical enclosures and light fittings.
- Food packaging, trays, and containers.
- Warehouse bins and supply chain handling tools.
- Agriculture and irrigation parts.
- Retail product casings and display components.
FAQs
Yes! Our team provides CAD design assistance and offers 3D printing or low-volume moulding for prototyping. We ensure your design is manufacturable before tooling investment.
We work with ABS, polypropylene, polycarbonate, polyethylene, nylon, and glass-filled polymers. We also offer FDA-compliant, flame-retardant, and medical-grade options.
New tooling projects typically take 2 - 6 weeks for tooling and samples. Repeat orders or existing tools can ship in days. We prioritise urgent requests where possible.
Absolutely. We accommodate one-off prototypes, pilot runs, and full-scale production with no minimum order constraints.
No - we ship nationwide. But our location means clients in the North East benefit from faster logistics, easier communication, and regional insight.
