Spray curing treatment of aluminum profile shell

by:Zeyi     2021-10-21
Three spray coatings generally require secondary curing. Aluminum is processed in a curing oven. The curing temperature is generally between 180°C and 250°C, and the curing time is 15-25 minutes. Different fluorocarbon coating manufacturers provide the best Optimal temperature and time. Some chlorocarbon sprays change from three sprays to three sprays instead of one curing based on their own experience. The surface quality of aluminum profiles also has defects such as warpage, deformation, black lines, convex, concave, white lines, etc. The design level is high, and the mold design and production process are reasonable, which can avoid the above-mentioned defects. Defect detection should be carried out in accordance with the inspection method prescribed by the country, that is, the defect is identified by the line of vision 40~50cm, but it also has its own purpose and purpose: The aluminum profile shell of the controller is changed by changing the wiring of the main circuit or the control circuit and according to the predetermined sequence Change the resistance value in the circuit to control the starting, speed regulation, braking and reverse main device of the motor. The shell can be divided into metal shell, plastic shell and so on. Shells are generally used in mechanical products, digital products, lamps and other products. Especially for the recently advocated LED energy-saving lamps, the shell has become a major additional product. Aluminum profile shell is the most widely used non-ferrous metal structural material in industry, widely used in aviation, aerospace, automobile, machinery manufacturing, shipping, chemical industry, etc. industry. Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. In addition to the application of aluminum profile in the shell, it is also widely used in furniture: screen frame, various suspension beams, table feet, decorative strips, handles, wire grooves and covers, chair tubes, etc., can be designed and used in a variety of ways ! The production process of aluminum profile shell mainly includes three processes: casting, extrusion, and coloring. The coloring mainly includes oxidation, electrophoresis, fluorocarbon spraying, powder spraying, wood grain transfer printing and so on.
