Powder coating process is the method that is for making the final product. It is industrial process to paint the metals of other related products. Basically in this process we need some instruments and materials. Please find the process points below.
The main segment of Powder Coating Plant.
- PT Line – Cleaning of product
- Powder Coating Booth
- Coating Oven
- Powder Coating Gun
Let’s say, our product is manufactured and ready to coat. We will start with PT lines/ Pre Treatment line.
Typically, adhesion between a paint coating and steel sheet is not very good. That’s why in Powder coating process, it is recommended to apply some type of intermediate layer, a pretreatment, to develop good long-term performance. Not only does the pretreatment improve the mechanical adhesion between the paint and the coating, but it also improves the resistance to blistering and loss of paint adhesion during exposure to corrosive environments.
Steps are:
- Hot Water Rinse
- Knock-off-Degrease
- Degrease
- Water Rinse
- Water Rinse
- Activation
- Phosphating
- Rinse
- Drying
After Pretreatment, out product is ready for powder coating, now we will take our product to the Powder Coating Booth. With the help of manual gun or reciprocators we will apply charged powder on the surface, let’s see how.
