Why Choose Huaxiao for Metal Special Process Parts?

Industry-leading capabilities backed by ISO 9001:2015 certification and 15+ years of precision manufacturing experience.

Heat Treatment

Quenching and tempering, carburizing, nitriding, induction hardening, annealing, and stress relieving — optimizing your part’s mechanical properties.

Surface Coating and Plating

Electroplating (zinc, nickel, chrome, gold), anodizing (Type II and III hardcoat), electroless nickel, DLC coating, PVD, and powder coating.

Precision Grinding

Surface grinding, cylindrical grinding, centerless grinding, and honing to tolerances of ±0.001mm and surface finish as fine as Ra 0.1µm.

EDM and Wire Cutting

Electrical discharge machining for hardened materials, complex cavities, narrow slots, and features conventional cutting cannot achieve.

Special Processes

Passivation, shot peening, laser marking, chemical etching, polishing, and completely bespoke finishing solutions.

Frequently Asked Questions

What surface treatment is best for corrosion resistance?

For mild environments, zinc plating or Type II anodizing works well. For marine or chemical exposure, we recommend stainless steel with electropolishing, hot-dip galvanizing, or electroless nickel plating.

Can you handle both manufacturing and surface treatment?

Yes — we manufacture the part AND apply surface treatment in-house. This eliminates logistics between suppliers and ensures quality continuity.

What heat treatment processes do you offer?

We offer quenching and tempering (up to HRC 65), case hardening (carburizing to 1.5mm case depth, nitriding), induction hardening for localized wear resistance, and annealing/stress relieving.

Do you provide coating certification and test reports?

Absolutely. We provide coating thickness reports, salt spray test results (ASTM B117, up to 1,000 hours), adhesion test reports, and Certificates of Conformance for every batch.
