What to send

The quickest way to an accurate quote

A drawing with dimensions and tolerances, the material, the quantity and the date you need the parts is enough for us to price most jobs. PDF drawings are fine; a STEP or IGES model helps on complex parts.

Tell us whether the material will be free-issued or whether we should source it, and whether the parts need any inspection records or certificates.

If a part is close to the limits of our machines, we tell you straight away rather than after a long wait. Prices are ex works unless agreed otherwise, and we can arrange delivery.
