SURFACE CONDITION
Surface Finishing
Select and control surface preparation or finishing according to material, corrosion exposure, functional surfaces, appearance, masking and the governing customer specification.

SERVICE OVERVIEW
Connect the service scope to the finished-part requirement.
A finish name alone is rarely a complete manufacturing requirement. The base material, incoming surface, target function, color or texture, coating thickness, masking zones, adhesion expectations and acceptance method can all affect process choice.
Surface finishing is reviewed with machining and inspection because coating or material removal may change fits, threads, sealing surfaces and measured dimensions. When an approved specialist supplier is used, the required specification, lot identification and applicable records remain part of the agreed project scope.
CUSTOMER INPUTS
Information required for an actionable review.
Incomplete requirements can change the quotation, process route and inspection scope. These inputs help identify open items before production planning.
Base material and condition
Alloy or grade, heat-treated condition and current surface state.
Finish specification
Customer standard, process designation, color, texture or approved reference sample where applicable.
Functional purpose
Corrosion protection, cleanliness, adhesion, wear, appearance or another defined objective.
Critical and masked areas
Threads, bores, sealing faces, electrical contacts, datum surfaces and no-coat zones.
Acceptance and test requirements
Appearance limits, thickness, adhesion, corrosion test or other agreed verification.
SERVICE SCOPE
Available work is confirmed by project, not by a generic checklist.
The execution route may combine Tianluping operations and controlled specialist suppliers. The quotation defines what is included.
Blasting and surface preparation
Clean or texture the surface using a method and media compatible with the material and finished-part requirements.
Project-definedPolishing and mechanical finishing
Establish an agreed visual or functional surface while protecting geometry, edges and critical interfaces.
Project-definedPickling and passivation
Review stainless-steel cleaning and passive-surface requirements against the specified material and governing procedure.
Supplier-managedPlating and conversion coatings
Coordinate the specified coating system, thickness, masking and applicable verification for suitable base materials.
Supplier-managedAnodizing
Review aluminum alloy, color, thickness, dimensional effect, electrical contact and masking requirements.
Supplier-managedPowder coating or painting
Define preparation, color or reference standard, film requirements, masked areas and visual acceptance.
Supplier-managedPROJECT WORKFLOW
Review, approve and control the service route.
The exact milestones depend on the project, but responsibility and acceptance should be visible before production begins.
Requirement definition
Confirm the base material, desired function, governing specification, appearance and acceptance criteria.
OutputDefined finishing requirementCompatibility review
Review incoming condition, geometry, threads, sealing areas, masking and dimensional effects.
OutputProposed finish and protection planSample or reference approval
Use an agreed sample or documented acceptance method where color, texture or appearance requires validation.
OutputApproved appearance or process basisProduction finishing
Process identified production lots with required preparation, masking and handling controls.
OutputFinished and identified partsFinal verification
Check agreed visual, dimensional or test requirements and collect included records.
OutputAccepted finish and project recordsDELIVERABLES & RESPONSIBILITY
Agree what will be supplied and what evidence is required.
Deliverables are project-specific and should be included in the quotation, approval plan or quality agreement.
PROJECT QUESTIONS
Questions to clarify before quotation.
How should a surface finish be specified?
Identify the base material, governing finish specification, functional purpose, color or texture where applicable, masked areas and acceptance method. A generic finish name may not define a reproducible requirement.
Can coating affect dimensions?
Yes. Added coating thickness or material-removal processes can affect fits, threads and sealing interfaces. Critical areas and masking should be reviewed before production.
Are all finishes completed in-house?
No blanket claim is made. The quotation identifies the confirmed execution route and any approved specialist supplier involved in the project.
Is a color name enough for approval?
Where appearance is important, a recognized color system, controlled specification or approved physical sample is preferable to an informal color description.
ENGINEERING REVIEW
Define the complete scope before quotation.
Share the drawing, material, quantity, application and required records. The team can review the manufacturing and supporting-service route together.
