Capability / Surface Finishing

Surface finishing selected for appearance, protection and assembly

Finishing is an engineering choice. Color, texture, corrosion protection, electrical behavior and dimensional change must be reviewed together.

Surface Finishing in project context

Surface treatment can improve appearance, corrosion resistance, wear behavior, thermal performance and assembly compatibility. The correct finish depends on the alloy, environment, masking requirement and cosmetic standard.

Anodizing, powder coating, plating, polishing, sandblasting, painting and passivation run in-house, so finish, masking and inspection stay on one production route.

Technical profile

Surface Finishing planning data

Use this table for project planning, then confirm every critical value against the approved drawing and process plan.

Finishing options	Anodizing, powder coating, plating, polishing, sandblasting, painting, passivation and chromate conversion by project
Appearance control	Color, gloss, texture and cosmetic zone to be approved by sample
Corrosion target	Defined by operating environment and test requirement
Masking	Threads, seals, contacts and critical dimensions must be identified
In-house	Anodizing, powder coating, plating, polishing, painting and blasting
Inspection	Visual, thickness and adhesion checks defined by finish and drawing

Figures reflect current factory equipment and capacity. Final tolerances, cycle time and lead times are confirmed against the drawing in the quotation.

Project flow

How a surface finishing project moves forward

Each stage produces a decision or document that the next stage depends on. This keeps engineering, purchasing and production aligned.

Use-case review

Confirm the environmental, visual and electrical requirement.

Finish selection

Compare process cost, durability, appearance and dimensional impact.

Sample approval

Approve color, texture, gloss and masking boundary.

Production control

Use the approved process and inspection plan for each batch.

Buyer questions

Questions to resolve before production.

These answers define the normal project path and the information needed for a useful quotation.

What information is needed for a surface finishing review?

Provide the controlled 2D/3D drawing, material requirement, annual quantity, finishing requirement, critical dimensions, target market and delivery date.

Can the project start from a sample or concept?

An initial feasibility discussion is possible, but the quotation and tooling scope should be based on a controlled drawing revision.

How are tolerances set?

Tolerance and inspection requirements are defined from the drawing, critical features, process capability and agreed datum strategy.

How is tooling ownership handled?

Ownership, storage, maintenance and transfer terms are defined in the quotation or supply agreement before the tooling project starts.
