Chrome Plating and Hard Chrome Surface Treatment Capabilities

Chrome plating changes how a precision part resists wear, controls friction, restores dimensions, protects against corrosion and presents its final appearance. SinoCMI helps match each chrome system to the base material, geometry, tolerance stack and application environment.

Hard Chrome

Hard Chrome Plating

Wear-resistant chrome for shafts, rods, rollers and sliding surfaces that need hardness, low friction and dimensional restoration.

Chrome

Decorative Chrome Plating

Bright cosmetic chrome over nickel or copper underlayers for visible parts that need appearance and corrosion resistance.

Industrial

Industrial Chrome on Functional Surfaces

Controlled chrome build-up for molds, dies, tooling, valves and sealing features that need extended service life.

Finish

Polish, Grind and Rework Support

Post-plate polishing, grinding or lapping planning for parts where chrome thickness and finish quality must align with tolerance needs.

Application fit

When to Specify Chrome Plating for Custom Parts

Specify chrome plating when the base material needs a hard, wear-resistant and controlled surface layer for sliding contact, corrosion resistance, appearance or dimensional recovery.

  • Shafts, rods, rollers and cylinders need hard chrome for wear resistance, hardness and lower friction.
  • Visible hardware, trims and handles need decorative chrome for bright appearance and corrosion resistance.
  • Molds, dies and tooling need chrome to extend service life and control surface wear.
  • Threads, bores, sealing lands and precision fits need masking or machining allowance before plating buildup.
  • Drawings specify coating thickness, hardness, surface roughness, embrittlement relief or inspection records.

Custom Parts That Benefit from Chrome Plating

SinoCMI supports chrome plating for custom components where wear resistance, hardness, low friction, corrosion protection and dimensional fit must work together.

Base Materials, Chrome Plating Systems and Finish Compatibility

Chrome plating selection should start with the substrate and final function. SinoCMI reviews base material, pretreatment, underlayers, masking areas, coating thickness, critical dimensions and post-treatment requirements before confirming a practical chrome route.

Steel and Stainless Steel

  • Hard chrome plating for wear, hardness, sliding and dimensional restoration
  • Decorative chrome over nickel underlayers for appearance and corrosion resistance
  • Preparation, activation and post-treatment selected for adhesion and service environment

Aluminum, Copper and Brass

  • Chrome plating with copper or nickel underlayers depending on alloy and application
  • Surface preparation reviewed for reliable adhesion and visible finish quality
  • Appearance, corrosion resistance and dimensional targets considered during RFQ

Engineering and Drawing Considerations

  • Mask threads, bores, sealing lands and no-plate surfaces as needed
  • Include chrome buildup in tolerance plans for shafts, holes and sliding interfaces
  • Define coating thickness, hardness, appearance grade, inspection level and applicable standards

Chrome Plating Thickness, Adhesion and Quality Documentation

Chrome plated parts should be verified against functional, cosmetic and dimensional requirements. SinoCMI can plan chrome allowance, masking, inspection checkpoints, test methods and supporting records during the RFQ stage.
