ALUMINUM SURFACE FINISHING
Surface Finishing for OEM Components
ONTOPS coordinates surface finishing with casting, extrusion, CNC machining and assembly. Available project routes include anodizing, powder coating, tin plating and mechanical finishing, selected according to the material, application and customer specification.
Surface Finishing Options
Anodizing
Anodizing forms an oxide layer on aluminum. Alloy, appearance, masking and coating requirements are reviewed for each part.
Powder Coating
Applied color and texture for aluminum components. Define pretreatment, color reference, masking and performance requirements for the application.
Plating
Tin plating and specified zinc plating are reviewed for the base material, electrical interfaces and corrosion requirements.
Mechanical Finishing
Shot blasting, polishing and vibratory finishing prepare or refine surfaces. Agree appearance, edge condition and handling requirements.
A Range of Surface Finishes
Glossy
Highly reflective, elegant, and easy to clean. Popular for interiors and electronic equipment.
Matte
Non-reflective, conceals minor imperfections, and resists fingerprints. Ideal for aluminum doors and architectural frames.
Textured
A textured surface adds visual depth and resists scratches. Suitable for outdoor equipment.
Wood Grain
Heat-transfer sublimation creates a natural wood appearance on powder-coated extruded aluminum profiles.
Equipment & Process
From Finish Selection to Inspection
Match the treatment to the base material and intended use. Agree appearance, functional surfaces and acceptance criteria before production.
01
Drawing & Finish Review
Review alloy, service environment, coating specification and visible surfaces. Confirm the required finish and inspection scope.
02
Preparation & Masking
Plan cleaning and preparation for the selected treatment. Protect threads, bores, sealing faces and electrical contact areas.
03
Controlled Surface Treatment
Apply the agreed anodizing, coating, plating or mechanical finishing route. Process parameters follow the approved specification.
04
Inspection & Packaging
Inspect appearance and the specified coating or functional criteria. Testing, records and protective packaging are agreed for the order.
