  • filling with the active product (hairspray, insecticide, lubricant, etc.)
  • fitting and fixing of the valve
  • filling up with the gas propellant
  • compulsory immersion in water to check the resistance of the can to pressure and to detect any leaks; elimination of defective aerosols
  • automatic weighing
