The Power of Plastic Injection Moulding

Plastic injection moulding is ideal for high-volume production and high-precision components. In this process, molten thermoplastic is injected into a custom-designed mould, rapidly cooled, and ejected as a finished part—ready for use or assembly.

Benefits include:

  • Excellent repeatability.
  • Low per-unit costs at scale.
  • Design freedom for intricate details.
  • Fast production cycles.
  • Broad material compatibility.

Stephens Plastic Mouldings offers all this with engineering input and quality assurance built in from day one.

FAQs – Plastic Injection Moulding Exeter

Can you handle medical or regulated components?

Yes. We manufacture parts for regulated sectors and follow strict documentation protocols. We also work with medical-grade materials where required.

Do you help during the product development stage?

Absolutely. Our DFM (Design for Manufacture) engineers will assess your CAD files and make recommendations to improve tooling life, part performance, and cost-efficiency.

What is your standard turnaround time?

Tooling typically takes 3 - 5 weeks. Initial production runs are usually delivered within 2 - 3 weeks depending on part complexity and volume.

Do I need to provide a tool, or do you make it?

We design and manufacture all tools in-house. If you already have a tool, we can assess and use it after testing and approval.

Is there a minimum order quantity?

No. We support low-volume runs as well as large-scale production, making our services ideal for prototypes, niche markets, or initial product launches.
