  • Pretreatment system
  • Air compressor
  • Powder spray system
  • Powder coating booth with recovery system
  • Curing oven
Pretreatment system consists of tank either filled with chemicals or water. The components which are going to be powder coated are dipped in the chemical to make the clean for the process. The size of the tank varies in accordance of the requirement and the components need to be coated.
