Powder coated square tube profile

  In recent years, with the continuous promotion of powder coating surface treatment technology, the market has increasingly high requirements for the surface quality of powder coating. This requires enterprises to have better control over every step of the production process, from the selection of spray powder, to the improvement of spray equipment, to the operation of production workers.   In addition, 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.  Powder coated square tube aluminium profile is a rectangular tube made of aluminum alloy, which have different specifications and dimension due to its dif…
