BLESS / Surface Finishing

Define the surface.
Plan the finish.

BLESS provides painting and powder coating within its aluminum component production route. The project specification defines which surfaces are coated, protected or left for assembly.

The route starts
with the requirement

Surface requirements should be discussed alongside casting and machining. Identify visible faces, mating interfaces and areas that must remain protected so the agreed finishing scope can be included in the project plan.

  • Finish requirementSpecify painting or powder coating requirements and identify any points still open for discussion.
  • Appearance facesMark the surfaces whose appearance is part of acceptance and describe the agreed reference.
  • Protected featuresIdentify threads, mating areas and other surfaces requiring protection during finishing.
  • Final acceptanceConfirm the surface checks, packaging and handling requirements for the finished part.

Define the scope
before production

Tooling, material, manufacturing suitability and inspection requirements are confirmed against your drawing.

Timing Confirmed per project

Manufacturing requirements, inspection scope and timing are confirmed per project.

The part needs
the right evidence

BLESS uses CMM, spectrometry, tensile testing and NDT. The drawing and agreed acceptance criteria define the inspection scope.

01 / CHECK

Inspect the part

Measure agreed features with CMM and the methods specified for the project.

02 / RECORD

Prepare evidence

Material, dimensional and mechanical-property reports can accompany the order.

03 / PROTECT

Pack for transit

Discuss packaging and handling requirements for the finished components.

04 / RELEASE

Confirm shipment

Confirm destination, packaging, requested records and project-specific timing.

Frequently asked questions

What does a custom aluminum casting supplier need to quote an OEM component?

Provide a drawing with its revision, the intended application, estimated order quantity and project stage. Identify the required material specification, critical dimensions, machining, surface requirements and inspection records. If an item is undecided, mark it for discussion rather than assuming a standard specification.

How should I specify material and inspection for custom aluminum components?

State the alloy designation and applicable standard if your design already specifies them. List critical dimensions, surface conditions and the checks or records you require. Material availability, manufacturing suitability and the inspection scope need to be confirmed for the individual project.

What should overseas procurement teams clarify before ordering?

Clarify the drawing revision, quantities, sample approval requirements, inspection records, packaging and requested delivery destination. Ask for project-specific confirmation of commercial terms and timing. A requested delivery date should not be treated as a confirmed lead time.
