A customer ask as following of automatic electrostatic spray gun 

Dear sir very good morning. Yesterday i had a discussion with one of my customer. He is using the 2K paint. Know he want to go in robotics. But he want to use the mixing of the 2k paint at robot arm. He want 2 gear pumps with servo motor at robot arm and on the controller the customer selects the ratio of Paint & Hardner at the controller according to it the gear pump rotates. Do you have any such system. He want to save maximum paint during colour change. If he mix the paint at robot arm then just few cc of paint is waste. Please find the attached photographs of the concepts.

yes we have the automatic meet the requirment
