Metal Finishing Companies in China

Lead times depend on pretreatment, coating specification, part volume, masking, color matching, and inspection requirements. If you have a required finish standard, include it when submitting your sourcing request.

You can manage communication and project tracking within the platform. A dedicated account manager can also support clarification, supplier comparison, and follow-up during the sourcing process.

A heat treatment company changes metal properties through controlled heating and cooling. Common services include annealing, quenching, tempering, carburizing, nitriding, stress relieving, and normalizing. The goal may be hardness, toughness, wear resistance, machinability, dimensional stability, or preparation for later manufacturing steps.

The four commonly discussed heat treatment categories are annealing, normalizing, hardening, and tempering. In production sourcing, the exact process should be tied to the material grade, hardness target, distortion limit, inspection requirement, and any downstream machining or finishing steps.

For heat treatment quotes, provide material grade, part drawings, current condition, target hardness, case depth if required, distortion limits, batch quantity, test standard, certificates, and any post-treatment cleaning or finishing needs. That information defines both the process and the inspection scope.
