Outdoor furniture is exposed to sunlight, rain and temperature changes for a long time. The coating needs excellent weathering resistance, adhesion and UV resistance. Powder coating has become the mainstream finishing method for outdoor furniture and aluminum products because of its environmental friendliness and durability. Taizhou Yufeng Intelligent Equipment Co., Ltd. plans powder coating lines for outdoor product companies to guarantee coating quality.
Pretreatment and the basis of weathering resistance
The durability of outdoor product coating first depends on pretreatment. Aluminum products undergo degreasing, oil removal and conversion coating to enhance adhesion. Steel products undergo degreasing, derusting and phosphating. Pretreatment quality directly affects coating weathering resistance, and bath parameters are inspected and controlled regularly. For corrosive environments such as coastal areas, the pretreatment standard needs to be strengthened.
Powder coating and curing process
Powder coating uses electrostatic guns, and the powder adheres to the workpiece surface with uniform thickness. The powder booth is equipped with a recovery system to improve utilization. The curing oven sets temperature and time according to the powder type. Outdoor powder usually requires a higher curing temperature to ensure cross-linking. After curing, coating performance is verified by impact, bending, adhesion, salt spray and UV aging tests.
Coating performance testing
Outdoor product coatings are tested for weathering resistance according to standards. The salt spray test simulates corrosive environments, and the UV aging test simulates sunlight, checking for color change, chalking and peeling. The test period is long, so routine production combines fast testing with sampling. Test data is recorded as the basis of product quality.
Racks and capacity
Outdoor furniture has many shapes. Rack design considers effective loading and powder coverage. Racks are cleaned regularly to remove powder accumulation and maintain conductivity. The powder line cycle is designed according to output, and the curing oven capacity matches the spraying speed. The line reserves extension positions for capacity growth.
Project planning
When planning an outdoor furniture powder coating line, provide the product material, size, output, coating colors and weathering requirement. We design the pretreatment tanks, powder booth, curing oven and testing plan, and provide the equipment list and investment estimate.
