Our Workflow
End-to-End Surface Finishing Process
Part Evaluation & Preparation
Inspect raw parts for defects (e.g., burrs, scratches) and confirm material compatibility with chosen finish (e.g., aluminum for anodizing).
Pre-Treatment
Remove contaminants via degreasing (solvent/alkaline cleaning) and sandblasting/etching to enhance surface adhesion for coatings.
Post-Preparation Cleaning
Rinse parts with deionized water to remove residual chemicals (critical for anodizing/plating to avoid finish defects).
Finish Application
Apply chosen treatment via automated lines: anodizing (electrolytic process), powder coating (electrostatic spray), or plating (electrodeposition).
Curing & Sealing
Oven-cure powder coatings (180–200°C) or seal anodized layers (chromate/sealer dip) to lock in durability and corrosion resistance.
Quality Validation
Conduct multi-point checks: salt spray testing (ASTM B117), thickness measurement (gauge/microscope), and adhesion testing (cross-cut method).
Quality Control Process
Rigorous QC for Consistent Results
Dimensional Accuracy
Focus：Verify coating/plating thickness (anodizing: 10–50μm; powder coating: 50–100μm) to meet spec limits. Standard：Complies with ISO 2808 for coating thickness measurement.
Environmental Resistance
Focus：Evaluate corrosion resistance (≥500 hours for anodized parts; ≥1,000 hours for powder coating). Application：Critical for aerospace, marine, and outdoor industrial parts.
Adhesion Integrity
Focus：Ensure coatings/platings bond securely to substrates (no flaking or peeling). Use Case：Vital for high-stress parts like automotive frames and tooling.
Visual Quality
Focus：Detect defects (bubbles, pinholes, uneven coverage) and verify finish uniformity. Standard：Meets customer aesthetic specs (e.g., mirror polish Ra ≤0.8μm).
