Process for removing paint from steel:

Part A - The paint (Black 075121) was applied to the part and left to dry at room temperature for 48 hours. The part was then placed in the basket and submerged in the tank and set for a cycle time of 5 minutes. After the part was inspected and all the paint had been removed. The part was then placed in a non ultrasonic rinse tank for 3 minutes to neutralize and remove any left on paint debris. Finally the part was placed standing up in the hot air dryer for 5 minutes at 70°C

Part B - Again the paint (Charcoal metal flake 070921) was applied to the part and left to dry for 48 hours. The part was then placed in the basket and submerged in the tank for a cycle time of 10 minutes. The part was inspected and some paint still remain, the charcoal metal flake is more stubborn to remove and required more time in the ultrasonic. The part was cleaned for a further 10 minutes inspected and was paint free, total cleaning time of 20 minutes. The part was then placed in a non ultrasonic rinse tank for 3 minutes to neutralize and remove any left on paint debris. Finally the part was placed standing up in the hot air dryer for 5 minutes at 70°C
