37 resources

Anodizing, Conversion Films & Coatings

Compare anodizing, conversion films, powder coating and other coatings through substrate compatibility, thickness and the properties required after finishing.

26 resources

Surface Preparation, Plating & Inspection

Compare mechanical preparation, plating and passivation around the substrate, finish standard, corrosion requirements and inspection plan.

Before you release the project

  1. Define the function, environment and the question this batch must answer.
  2. Specify material grade, geometry, quantity, finish and the dimensions that control fit.
  3. Agree the inspection method and the evidence required to accept the parts.
  4. Record the drawing revision and approval before production begins.

Common planning questions

When should the finish be specified?

Before production. Film thickness, masking, substrate preparation and cosmetic requirements can change dimensions, conductivity and assembly fit.

Is one finish suitable for every alloy?

No. Substrate chemistry, condition and service environment influence preparation and compatibility. Specify the actual alloy and intended use.

Move from guidance to a reviewed project

Send the CAD model and drawing with material, quantity, finish and inspection requirements. Use the relevant service page to review the available manufacturing route.
