Non-standard forgings to drawing — complex profiles, thin walls, tight tolerances.

| Documentation | Material certificate, dimensional report, UT/PT/MT reports |
When the geometry does not exist in a catalogue, the part is forged to drawing. That covers curved support brackets, valve bodies, impeller blanks, thin-wall housings and anything else where a machined-from-solid part would waste material or lose grain flow.
Send a drawing or STEP file with the material, heat-treatment condition and inspection requirements. We return a forging drawing, a process route and a price.
Open-die, closed-die or isothermal forging is selected by geometry and lot size; machining, heat treatment and surface finishing can be included.
As-forged tolerance to GB/T 908-2019; machined features to your drawing, with position tolerances down to ±0.1 mm where specified.
UT, PT and MT are available; micro-focused dimensional inspection for thin-wall sections.
Seamless rolled rings up to 7.5 m outside diameter, IT7–IT9 tolerance.
