Overspray in industrial finishing applications is one of the most common causes of parts being rejected by quality control inspections. This can result in constant costly reworks and low-quality finish on parts. In this case study, Air Power proposes a solution that completely eliminates overspray for this customer.
Manufacturer of plumbing and water-related fittings and valves
This customer was experiencing paint buildup on their booth due to overspray. This was caused by inefficient airflow through the booth. This customer was using an old baffle style booth that uses offset layers of metal to catch the initial overspray and then redirects the overspray into the second layer of filters. As a second layer of filtration, the customer used Styrofoam baffle filters that allowed a high volume of bypass of a mixture of tacky and dry overspray. This type of baffle filter works better with wet paint overspray.
Without proper airflow collecting the overspray in the booth, this customer experienced a higher number of rejected parts, a lower quality finish on products, and paint buildup on their spray booth and surrounding areas.
Air Power Solution
Air Power proposed a solution that updated the filtration system to a more efficient style. This solution included completely removing the metal vertical baffles that were the first stage of filtration. The second stage Styrofoam baffle filters were then removed and the 20×20 grid was scraped clean of all the overspray buildup. Then we installed Kem-Wove P3 20×20 panel filters in the second stage, installed snapper bars on the front of the filter wall, and added RP 3252 paper/poly blankets (RTT Engineered Solutions / Col-Met) as the first stage of filtration to improve overspray capture and airflow.
This customer was amazed by the change in airflow and overspray capture in their spray booth. This new filtration system collected all the overspray in the booth and allowed nothing to bypass for the first time. These changes improved the painting conditions for operators in the booth, allowing for a higher quality finish on products. This customer is currently in the testing stage with this system to determine the length of life for one layer of filtration to ensure this system is cost-efficient and establish best practices for their finishing operation.

When it comes to mixing paint, accuracy is the key to achieving a high-quality finish. In this case study, we discuss a 2K solution that helped this customer perfect their process and save tons in production costs.
Manufacturer of roadside transformers.
This company has a small parts booth for primer and topcoats. The operator had to manually mix two types of epoxy and one urethane. Each day he had to spray all three colors from the same hot pot system. The color change process was a major problem as the different parts to be sprayed were not batched. This caused a lot of waste of paint and solvent. The other concern was being off ratio and parts not curing properly. This was a major cost to the company. They also had a large booth that sprayed the finished transformer. They had to utilize the same paints and this process had the same problems. If the large transformer was off ratio, they had to sand the paint off and repeat the entire process. This proved to be a very expensive problem.
Air Power Solution
Air Power proposed to install a Carlisle GEMS 2K mix system for each color. We also put in a pump system to pump and circulate all paints to the mix machines. The catalyst was dispensed to the machines from 5-gallon pressure tanks. The 55-gallon drums of paint each had an agitator in them to keep paint in suspension to maintain viscosity. By having a machine for each color there was no color change or off ratio problems.
The Air Power Solution eliminated the need to hot pot in tanks. Since each color is mixed on demand; this system provided a major labor savings. There is no paint waste and the newly established process saves about 2 to 3 hours per shift as compared to manually formulating and mixing paint. The solvent usage was greatly reduced as there was not a tank to clean each color change. This solution has been able to speed up production on all three shifts. Our technical group and installers were able to put the system in place without impeding the customer’s production runs.
