Suitable Appliances

Built-in ovens, commercial kitchen appliances, high-power electrical equipment

2. Surface Coating Selection: Align with Appearance & Service Environment

Key Consideration

Select coatings based on aesthetic requirements, cleaning frequency, and exposure to humidity/oil/food contact.

2.1 Polyester (PE) Coating

Specifications & Advantages

• Cost-effective, excellent color uniformity (ΔE ≤1.0)

• Good adhesion (≥4B cross-cut test) for indoor use

Suitable Appliances

Mass-produced standard appliances, low-humidity environment appliances (e.g., bedroom air conditioners)

2.2 Anti-Fingerprint (AF) Nano Coating

Specifications & Advantages

• Oil-repellent, dust-resistant, and easy to clean

• Maintains premium appearance for high-touch surfaces

Suitable Appliances

Refrigerator doors, washing machine front panels, high-end smart appliances

2.3 High-Hardness / Anti-Scratch Coating

Specifications & Advantages

• Surface hardness ≥3H (pencil test)

• Reduces damage during transportation, stamping, and daily use

Suitable Appliances

Appliance tops, side panels, high-traffic surfaces (e.g., dishwasher door panels)

2.4 Food-Safe Water-Based Coating

Specifications & Advantages

• Low VOC (≤50g/L), non-toxic, odorless

• Complies with FDA 21 CFR / GB 4806.9 food-contact standards

Suitable Appliances

Kitchen appliances, food-storage compartments, inner liners (e.g., refrigerator crisper drawers)

3. Aluminum Alloy & Thickness: Match to Processing & Structural Needs

3.1 Alloy Selection

3.1.1 1060 / 3003 Alloy

• Advantages: Excellent formability, low cost, easy stamping/bending

• Suitable for: Complex-shaped panels (e.g., curved refrigerator doors)

3.1.2 3105 Alloy

• Advantages: Higher rigidity, superior flatness (≤0.5mm/m tolerance)

• Suitable for: Large-size appliance panels (e.g., full-size refrigerator side panels)

3.1.3 5052 Alloy

• Advantages: High strength (≥150MPa), enhanced corrosion resistance

• Suitable for: Load-bearing appliance shells (e.g., washing machine drums, heavy-duty oven casings)

3.2 Panel Thickness

3mm ACM

• Advantages: Lightweight (≤6.0kg/m²), cost-efficient

• Suitable for: Small appliances, lightweight parts (e.g., toaster shells, small fan casings)

4mm ACM (Mainstream)

• Advantages: Balanced rigidity and weight (≤7.5kg/m²)

• Suitable for: Most household appliances (refrigerators, washers, air conditioners)

5–6mm ACM

• Advantages: High rigidity, impact resistance (≥6J)

• Suitable for: Heavy-duty, large-size shells (e.g., commercial refrigerator panels, industrial washing machines)

4. Performance Specifications: Tailor to Working Environment

4.1 Kitchen & High-Humidity Environments

• Required Performance: Salt spray resistance ≥1000h (PE coating) / ≥1500h (PVDF coating), moisture/oil resistance

• Example Appliances: Kitchen refrigerators, dishwashers, range hoods

4.2 High-Temperature Appliances

• Required Performance: Core heat resistance (≤120°C for PE / ≤150°C for FR-PE), coating thermal stability

• Example Appliances: Microwave ovens, built-in ovens, toasters

4.3 Indoor Long-Term Use

• Required Performance: Color stability (no fading for 5+ years), coating adhesion ≥4B, low warpage

• Example Appliances: Living room air conditioners, bedroom dehumidifiers

5. Safety Compliance: Meet Global Household Appliance Standards

Mandatory Certifications & Standards

• Food-Contact Safety: FDA 21 CFR §175.300, EU REACH (EC) No. 1907/2006, GB 4806.9-2016

• Fire Performance: GB 8624-2012 (B1/A1/A2), EU EN 13501

• Environmental Compliance: Low VOC, RoHS (restriction of hazardous substances)

Key Verification Tips

• Request batch test reports (salt spray, coating adhesion, fire rating)

• Confirm compliance with regional standards (e.g., UL for North America, CE for Europe)

6. Production Compatibility & Cost Efficiency

6.1 Production Line Compatibility

• For Automatic Stamping/Bending Lines: Choose ACM with high formability (minimum bending radius = 1.5×panel thickness) and flexible coating (no cracking/peeling)

• For Mass Production: Prioritize stable color consistency, low scrap rate (≤3%), and standard specifications

6.2 Cost Optimization Strategies

• Budget-Friendly Option: PE core + PE coating (25–35% cost savings vs. PVDF coating)

• High-End Positioning: Anti-fingerprint, metallic, or matte textured finishes (enhance product value)

• Long-Term Savings: Select durable materials (low defect rate ≤0.3%) to reduce rework/after-sales costs
