With the continuous improvement of equipment automation, powder coating control will become more precise, coating utilization rate will be higher, and equipment safety and stability will be guaranteed. The spraying distance mainly affects the coating thickness. Generally, it is more suitable to control the spraying distance between 150-250mm. Within this range, the powder deposition efficiency is relatively high. Aluminium construction profiles generally include door frame profiles, window frame profile, and glass frame profiles. Different models and specifications of aluminum extrusion profile window and door can be selected and customized according to needs. Aluminium profile window can provide structural stability, good sealing, sound insulation, insulation, and other functions, while also having a beautiful appearance, suitable for manufacturing windows of various architectural styles and purposes. Aluminum extrusion profiles become more and more important in mode…
