Gemini are experts in custom plastic injection moulding of complex components in a variety of materials for industries in the UK and worldwide. Our injection moulding services run from prototype to production, with finishing and assembly under the same roof so a single part can go from first-off to boxed dispatch without leaving the site.
Our Process
From the first sketch to the final boxed part, every stage runs in our own UK facilities. Nothing is subcontracted, one team, one site, and full accountability from enquiry to dispatch.
We refine your concept with in-house CAD and design-for-manufacture, then cut and prove the tooling on site, before a single part is made.
Your part is injection moulded in our own UK facilities, from first-off samples through to full production volumes, on our own presses.
Finishing, decoration, sub-assembly and packing all happen under the same roof, leaving us ready to dispatch a complete, inspected product.
In-House Capability
Material Selection
Material choice shapes how a part performs, how it looks and what it costs. These are the five factors we weigh with you before a tool is cut, mapped to the plastics we mould most.
Send us details about your part and we'll get back to you within 24 hours.

Case Studies
The nominally prototype parts were treated by Toyota as if they were actual production parts, and performed very well throughout test and validation. The overall quality and timing have been very strong.
