Recently, EXEL North America (Manufacturer of Kremlin Rexson) partnered with their local Solution & Service Center, SOT Abrasives and Equipment located in San Antonio, Texas to help an automotive customer create a solution that would finish interior plastic parts for a new division that had moved to the area.
Toyoda Gosei located in San Antonio, Texas is the interior components division of Toyota and they were looking for a solution that would finish the interior plastic parts of their Tundra and Tacoma model trucks. The problem was, this facility had never finished these plastic parts with a waterborne material so it was a new process for them.
EXEL North America and SOT Abrasives & Equipment were asked to come into the facility and offer expert advice on how to spray with a waterborne coating while delivering a fine finish with less overspray. Toyoda Gosei needed a proven solution to be installed very quickly and that is what EXEL North America and SOT delivered.
Toyoda Gosei currently has a Fanuc Robot application and their previous equipment consisted of solvent based product diaphragm pump and HVLP applications. Toyoda Gosei needed a high-efficiency system compatible with their new 1K Waterborne composite paint and they needed it installed very quickly!
Bud Slover and Phil Baker of SOT and Tom Dean with EXEL North America met with the Toyoda team that consisted of Simon Barcena, Jorge Cortes, and John Castillo to discuss the solution and action plan. They agreed upon an installation date, the order was placed, and shipped immediately for delivery.
The following equipment was quoted and installed:
(1) AVX Automatic Airmix® gun on the end of a Fanuc Robot
(2) Flowmax® Pumps – (1) for the waterborne material and (1) for flushing
(1) CTM – Color Change Valve (Paint – Flush)
(1) Circulation Valve
Several Fluid Pressure Regulators
(1) Customized stand for the Kremlin Rexson equipment
Within 15 days from quoting the job, the equipment was installed. After the equipment was installed, product trials went off perfectly! Within the first hour of trials, the parts were ready for production vehicles. This was a very fast implementation and installation by EXEL North America, SOT Abrasives and Equipment and the team at Toyoda. It only took two days to program and integrate the Kremlin Rexson equipment with the Fanuc Robot.
EXEL North America and SOT Abrasives and Equipment was able to provide Toyoda Gosei a system that delivered a fine finish with a much lower overspray than any other finishing application in their facility. We will continue to work with Toyota to help them improve their processes and save them money in the long run!

Ever rub a balloon against yourself and make it stick to a wall or other object? That is the basic idea of how an electrostatic paint sprayer works. The rubbing of the balloon causes it to obtain more free electrons, which makes a negative charge. The negatively charged balloon now will stick to neutral or positive objects. Ken Eyestone is our training manager at Exel North America, Inc. And according to him, electrostatic paint sprayers are the way to go to save paint, money and the environment.
- At the tip of the paint sprayer is a small electrode, which creates high voltage electricity. As the paint particles travel at a slow speed through this corona of electricity, they become negatively charged.
- The paint surface is the grounded, positively charged surface, which has a magnetic attraction to the negatively charged paint. As you spray the paint, the paint overspray may initially travel off in a different direction, but will turn back to the positively charged object and stick to it. The paint will stick to any surface that is conductive. Metal definitely. Wood has water in it, and the wetter the wood, the greater the positive charge. Surfaces that include plastic, stucco and wood that are old and very dry will need a thin coat of conductive adhesive promoter applied before painting.
- Electrostatic paint sprayers work well with an oil- or water-based paint. However, water has a stronger positive charge than oil. The paint needs to be able to hold a charge, but not be too conductive. Solvents can be added to paints to make them perfectly charged. Contact the manufacturer of the paint to see what, if anything needs to be added to the paint. The size and velocity of the paint particles is also important. The smaller the particle mass, the greater the attraction. The slower the particle, the greater the effect of the paint charge.
- The benefit of using an electrostatic paint sprayer is in the saving of paint. Expect to use 25 percent to 50 percent less paint. In a big job, that is a lot of paint and money saved. There is less waste which is good for the environment. There is very little overspray to clean, and the paint coverage also has a very nice, smooth look.
- If you have sharp edges, the paint will go on much thinker. The particles of paint are very attracted to corners and sharp edges. Where you have an inside corner, the paint goes on much thinner, if at all. This is called the Faraday Cage Effect. The solution to this problem is when spraying into a corner, the painter paints with electrostatics that are turned off for that part.
- If the surface to be painted is not grounded, the charged paint particles will search for the nearest ground. This will in all likelihood be the painter!

Finally, we have released the 2010 Robotic Guide! It has been updated with our latest products …. and of course will need to be updated in the next few months to show case all the new products we’re soon launching to add to our robotic product lines (new waterborne external charge bells, low-cost 2K/3K gear pump systems, off-the-shelf retrofit process arms! … just to name a few).
