What QC equipment do we need for Powder Coating?

We would like to put a plant of Powder Coating on Aluminum , Gl and Steel and would like to have QC equipment.
Can someone guide us what type of equipment we require for QC?

The question should not be what equipment to use, but what do you want to measure. This starts with what are you trying to achieve? If you want automotive finish, then you'll need certain instruments. If you want no specific standard for low expectation customers, then you might need no instruments at all!

Quality control can be as simple as using your eyes (as instrument) to measure the coating, to using extensive, expensive machinery to measure many attributes of the coating.

Your first step is to decide what you want to do. Do you wish to work to a standard?
If so what does that standard say you must do?
For example if the std you want to work to says you should have a certain thickness of coating, then you need coating thickness instruments.

So, perhaps you could re-phrase the question in light of what you are trying to achieve.

What the most important tests to be carried out on the powder coated components that qualifies the powder coating. We are using silver metallic powder with aluminium bonding on mild steel components that are meant for export to Europe countries. We check the components for coating thickness and cross hatch test and evaluate the quality. Are there any other important tests that can be done in-house which will further prove the quality of coating. Kindly suggest.
