Accelerating Innovation for Birmingham’s Automotive Sector
Birmingham remains a powerhouse in the UK’s automotive industry, with a proud legacy of innovation and advanced engineering. As vehicle platforms become lighter, smarter, and more modular, manufacturers are increasingly turning to plastic injection moulding to reduce weight, increase part precision, and optimise cost.
Stephens Plastic Mouldings supports automotive OEMs and Tier 1–2 suppliers with precision-moulded components, made in the UK and delivered on time. Whether you’re developing next-gen interior systems or electrification assemblies, we offer the tooling expertise, material knowledge, and volume flexibility your business needs.
Why Automotive Engineers Choose Injection Moulded Components
1. Lightweight Engineering
Injection moulded plastics such as PA6 (nylon), PC/ABS, and polypropylene reduce weight while maintaining rigidity — supporting fuel efficiency and electric vehicle range goals.
2. Complex Geometries with High Repeatability
Plastic injection moulding is ideal for intricate component designs with internal channels, snap fits, and texture finishes — all produced at scale with tight tolerances.
3. Cost-Effective at Volume
Once tooling is created, part costs remain low and predictable — ideal for mass production cycles common in the automotive sector.
4. Design Integration
Multi-part assemblies can be replaced with a single overmoulded or insert-moulded component, reducing build time and part numbers.
