Industry Coating Challenges

Each industry faces unique coating challenges. MUSI's solutions are designed to address these pain points directly:

High Visual Standards

Appliance exteriors are highly visible — strict requirements on color, smoothness, anti-fingerprint, etc.

Salt Spray Tests

Kitchen and laundry appliances used in humid environments must pass 480-1,000 hour salt spray tests.

Large & Complex Shapes

Refrigerator side panels and washing machine shells are large with deep-drawn and recessed structures.

Tight Supply Chain

Appliance OEMs enforce strict QC — suppliers must hold IATF/ISO and other certifications.

MUSI's Targeted Solutions

To address these challenges, MUSI provides industry-specific coating solutions:

1. Floor Belt Conveyor Spray Lines

Optimal for high-quality coating of large flat parts — belt widths up to 2,500 mm, load capacity up to 500 kg per station.

2. Electrostatic Powder Coating

Coating hardness 2H-3H with excellent mechanical properties — passes 1,000+ hours of salt spray.

3. Auto Inspection & Unload

Inline color and film thickness measurement; automatic rejection of non-conforming parts.

4. Standardized QC Documentation

Complete SOPs from pretreatment to finished part inspection — supports your appliance OEM audits.

Recommended Equipment

Typical projects in this industry use the following MUSI products in combination — exact selection depends on workpiece specifics:
