One supplier, start to finish

Casting and machining under one roof

The foundry and machine shop are in the same building. We quote the whole job, from raw material to finished part.

We specialise in low-volume and prototype work. No minimum order, from one part to a thousand. Prototypes are cast and machined the same way as production parts.
