What changes a cold heading die route before quotation?
Cold heading dies are often called cold forming dies in RFQs, but the name alone does not define the tooling route. The useful decision is whether the forming load, material flow, and die support call for a carbide core, a steel body, or a supported die-case assembly.
Machine and station
Send the machine model, station number, and forming sequence. A die that fits one station can fail early in another because the load path and support are different.
Blank and wire condition
Blank diameter tolerance, wire grade, hardness, lubrication, and surface condition affect cavity pressure before the finished bolt or screw is inspected.
Failure evidence
Photos of chipping, radial cracks, galling, folds, or dimensional drift help separate a material problem from a support, radius, or alignment problem.
A carbide die core will not solve a crack caused by weak case support or off-center load. Send the drawing, machine data, blank material, and failed-tool photos so the quote reflects the working condition rather than a generic die name.
