Color Coated Aluminum for Home Appliances

Core Advantages

• Excellent forming & coating adhesion: Optimized substrate and matched coating system support bending, stamping and shallow drawing without paint cracking, peeling or chipping during appliance fabrication.

• Uniform & stable coating performance: Continuous roller coating technology ensures consistent coating thickness, no pinholes or uneven color. Stable batch-to-batch color for mass appliance assembly.

• Good corrosion & stain resistance: Functional organic coating resists kitchen grease, moisture, fingerprint and daily abrasion, maintaining long-lasting appearance for indoor home appliance scenarios.

• Rich surface finish options: Available in solid color, matte, metallic, textured and brushed finishes. Custom Pantone color matching according to appliance design requirements.

• Superior thermal conductivity: Aluminum base delivers efficient heat transfer, ideal for heat-dissipating panels of refrigerators, ovens and heating household devices.

• Ready-to-use & high production efficiency: Pre-finished coating eliminates secondary painting at appliance factories, reduces VOC emission and shortens manufacturing cycle.

• Fully recyclable & eco-friendly: Aluminum material can be recycled repeatedly. Non-toxic coating formula meets global environmental standards for home appliance industry.

Production Process

Aluminum ingot melting & casting → Hot rolling → Cold rolling → Degreasing & surface pretreatment → Primer coating → Topcoat coating → High temperature curing → Flatness leveling → Slitting / shearing → Surface inspection → Coating performance test → Interleaving paper protection → Standard export packaging

Each batch will undergo adhesion test, impact test, color difference inspection and salt spray corrosion resistance test before shipment to guarantee stable coating quality for home appliance manufacturing.

Technical Parameters

Application

• Refrigerator components: Side panels, decorative trim and inner decorative parts for household refrigerators and freezers.

• Washing machine panels: Front & rear covers and decorative shells for automatic washing machines and dryers.

• Air conditioner casings: Outdoor & indoor unit decorative panels and frames for residential air conditioners.

• Small kitchen appliances: Shell materials for microwave ovens, water heaters, coffee machines and other kitchen electric devices.

Export Packaging

Color coated aluminum coil or sheet is separated by anti-scratch interleaving kraft paper. Wrapped tightly with moisture-proof PE film and waterproof kraft paper. Loaded on standard IPPC fumigated wooden pallets, secured with packing straps and stretch film to avoid shifting and surface coating damage. Shipping marks clearly show alloy grade, temper, thickness, width, coating type, net/gross weight and batch number. Complete MTC and certification documents can be provided for customs clearance and incoming quality inspection.

FAQ

Q1: What is the key advantage of color coated aluminum for home appliances? A1: It combines aluminum’s lightweight and heat dissipation properties with pre-finished coating. No secondary painting needed for appliance manufacturers, reduces VOC pollution and ensures beautiful, long-lasting surface performance.

Q2: Which coating type is recommended for kitchen appliances? A2: PE coating is cost-effective for indoor home appliances; HDP offers better color retention; PVDF is selected for scenarios requiring superior anti-fade and corrosion resistance.

Q3: Can the material be bent and stamped? A3: Yes, our matched substrate and coating system supports bending and shallow stamping, coating will not crack or peel under normal forming process.

Q4: Can custom colors and sizes be produced? A4: Fully customizable, we can match Pantone color and produce customized thickness, width according to your appliance drawing requirements.

Q5: Is batch quality consistent? A5: Continuous roller coating line with strict online color monitoring, stable coating thickness and color difference control, low batch variation for long-term mass production.
