Laser cutting and sheet metal, made in Marlow since 1964.
One-off prototypes to many thousands of parts. Cut on our 4 kW laser, formed, welded and finished under one roof.
Everything from the flat sheet to the finished assembly.
Laser cutting sits at the centre. Bending, punching, welding, fabrication and design are all in house, so a job does not leave the building until it is done.

- Full flying optics and quick-change lenses from 5" to 10"
- Laser Piercing Monitor for thick material
- Nitto laser guard coating left intact on request
