Crown are plastic injection moulding specialists and work across a wide range of sectors

We produce the highest quality small to medium plastic moulded parts that are distributed to manufacturers in the UK and worldwide. These moulded parts are always an integral part of a process or a component and that’s why precision is key in all areas of production.

From design to delivery we can take care of any part of the injection moulding process. The design process is critical so that an efficient tool can be made or modified to ensure that the product is moulded to your exact requirements. No matter how small or how big the production run nothing is ever left to chance. Our ISO 9001:2015 accreditation depends on our ongoing ability to quality control at each stage of the plastic injection moulding process.

Garage & Shutter doors

Medical & Pharmaceutical

Garden & Leisure


Electronics & Computers



Crown understands quality and deadlines and never compromises one to achieve the other. The capability is there to produce just in time deliveries and we can accommodate fast turnarounds if that’s what is required – we’re a very ‘can do’ team. When it comes to plastic injection moulding our experience will help you to plan accurately and confidently, we really are the ideal partner.

There are 27 moulding machines on site range from 35 tonne to 200 tonne. From our 15000 square feet purpose built facility in Builth Wells there are good road links with the Midlands, North West and South Wales.

Environmental factors are taken seriously. We take responsibility to ensure that at each stage of the injection moulding process we do everything we can to minimise waste and pollution. Working closely with the Environment Agency we have been able to refine our processes which has made us as lean and green as we can possibly be.

Whether you have a bespoke or standard injection moulding requirement please do get in touch and we look forward to hearing from you.

What our clients say....

Dear Neil and the Crown Team.

Just a quick festive thank you for your high standard of support this year and, indeed, throughout our business relationship. My colleagues and I have been very demanding at times (which is the nature of our business of course) and in every case your team has responded to ensure we get the solution we need when we need it; we could expect no more of any supplier, and from that point of view your performance has been first class. Could you please pass our thanks to everyone in your team for their continued support and wish them the very best for the Christmas and new year period.
