How we work
What we need to quote a casting
Send a 2D drawing with tolerances and a 3D model (STEP or IGES), the alloy grade and standard, the heat treatment, the order quantity and estimated annual volume, and which surfaces are machined. Tell us the inspection and certificate requirements at the same time, for example X-ray or penetrant testing, or an EN 10204 3.1 material certificate.
We check the part for castability first: wall sections, feeding, gate location, machining allowance and datums. If a change to the drawing would make the part easier or cheaper to cast, we say so with the quotation.
