Finishing Services

Parts finishing is reviewed against the part substrate, manufacturing process, controlled drawing, finish specification, visual reference and acceptance method.

Parts finishing project review

State the base material and process, finish requirement, color or visual reference, cosmetic surfaces, masking, threads, mating features and post-finish acceptance criteria.

A supplier can review the requirements and flag process interactions. The buyer retains final authority for design release, appearance approval and deviations.

Custom part surface finishing
Part finishing preparation

Confirm the finish per project

Anodizing, coating, plating, polishing, marking and other finishing routes are selected only where the substrate, geometry, specification and order requirements support them.

Finish decision inputs

Substrate

Identify the material and manufacturing route before selecting a finish.

Appearance

Provide color, texture, gloss and visual acceptance references.

Interfaces

Call out masking, threads, fits and critical dimensions.

Approval

Define inspection and buyer approval requirements per order.

Buyer decision guide

What finish information belongs in a custom-parts RFQ?

Specify the substrate, finish type, color or visual reference, cosmetic surfaces, masked areas, dimensional effects and acceptance method. A finish name alone may not define appearance or inspection needs, especially where coating interacts with threads, fits or critical dimensions.

Finishing RFQ inputs

  • Base material and manufacturing process
  • Finish specification and color reference
  • Cosmetic surfaces and acceptable variation
  • Masking, threads and mating features
  • Post-finish inspection requirements

Decision flow

  1. 01

    Define

    Connect the specified substrate, finish, appearance and functional needs to the controlled drawing.

  2. 02

    Review

    Review masking, threads, fits, cosmetic surfaces and dimensional interactions before release.

  3. 03

    Inspect & approve

    Use the agreed visual and dimensional acceptance method; buyer approval remains project-specific.
