St Davids Assemblies Ltd


We specialise in engineering polymers which are glass reinforced to give rigidity, good electrical insulation, and resistance to high temperatures. Components may also be flame retardant. Another speciality is producing components made from environmentally friendly polymers such as PLA and Sorona™.

We have recently invested in a new vertical ALLROUNDER injection moulding machine. The new machine allows us to precisely match to your specific injection moulding tasks, while still maintaining maximum ergonomic efficiency.

Pressings and Contactings

We operate several high speed presses ranging from 25 tonnes to 40 tonnes capability, incorporating all the latest technologies.

High speed progression tooling up to 650 strokes per minute using brass, beryllium copper, stainless steels, bimetals and copper iron. Silver contacting to brass, beryllium copper, stainless steels and bimetals.

We have many years of experience in welding difficult materials such as beryllium copper. Our processes and machines are monitored using statistical techniques.


We have been designing and assembling products by automated and hand since 1951 and have a very good insight into techniques that keep assembly times to a minimum.

Since 1994 we have invested millions of pounds in bespoke automation, which has been tailored to the customer requirement.

Tool Making

We can globally source tools and materials utilising our sister companies in China and India, we have two partners we currently work with in Asia. However, the vast majority of tooling is manufactured either in St Davids or utilising our UK supplier base.

Design and Prototyping

St Davids Assemblies has the expertise and resource to deal with your manufacturing requirements through new product innovation. Where more complex designs and parts are required we have inter-group facilities to call upon for 3D Prototyping.

Using a Solid Works CAD package and 3D modelling together with CNC machining we can quickly design and manufacture prototype tools and prototype parts.

Hand Assemblies

St Davids Assemblies offers expertise in small order hand assemblies for pre production and prototyping.
