PICTURES AND INFORMATION ON THERMAL PAINT REMOVAL SYSTEM
The picture top left is the control panel to a Blu-Surf bake-off oven. The picture top right is the actual process chamber. We use the oven as an intricate part of the stripping process for most ferrous metals. It is used to turn multiple layers of paint, undercoating, caulking, grease, stickers, powdercoating, body fillers, and other oxidizable substances into a thin and easily removed fly-ash. This fly-ash can then be removed with blasting or other physical means. When blasting, it gives us the benefits of faster production rates, at lower blasting pressures, using a finer grade of abrasive and producing a texture free physically etched surface for outstanding coating adhesion. This is the preferred method we have used for years to process rare classic and collectible automobile parts and bodies. You can view pictures of this process at work at the top of our web page PICTURES.It is also used to burn-off paint hooks and racks with extreme film buildups without damaging or warping the parts to be cleaned.
We charge by the oven load, by the basket load or by the piece for everything with the exception of hooks or paint racks. The total size of the process chamber is 13'x7'x6' and maximum weight of objects are limited 6K pounds per basket or 9 tons per ovenload. A typical process cycle runs between 2 to 12 hours with top temperatures of 800F. Process charges are generally $125.00 per ovenload based on percentage of space required with a minimum charge of $25.00 for anything. Racks and hooks are charged based on an hourly rate of $30.00 per hour and maximum safe processing rates of 20 to 30 pounds of paint per hour.
Metals like aluminum or zinc diecast cannot be subjected to the thermal process without deformation or loss of strength and must be removed before baking. It is also not advisable to bake springs, coils, or other heat treated objects as this will result in annealment of the steel and require additional heat treating to restore proper temper.

OVEN ADAPTER SIDE VIEW
The above two captions show an oven adapter that we designed and built to expand the oven capacity. It will now allow us to process parts with a maximum length of 18 feet and we can now accomodate all car bodies and all but the longest of frames. This oven can now process powdercoated race car frames without setting them on their sides or attempting a corner to corner configuration. It wasn't cheap and we charge extra for having to use it when the part exceeds 12' 6" . This extention was successfully operational as of April 4th, 2003.

100 HP QUINCY QSI 490 WC
75 HP SULLAIR WC
All this blasting equipment can really use the air. It cannot be overstated that blasting can require substantial amounts of compressed air. We run three electric compressors in our blasting operations and have the ability to select one at a time or all three can be run at the same time if necessary. Above is a picture of the 100 hp Quincy QSI 490 and the 75 hp Sullair compressors. The 50 hp Quincy QSI 235 that we started with has not been pictured and is far less pretty but still runs great and is extremely reliable.
Personally, it is our opinion that the best compressors on the market today are built by Quincy. Specifically, we suggest that all blasting operations consider the Quincy QSI series for all blasting applications. The QSI units are built for industry and generally cost twice that of any other brand on the market. But they are built to last and we have over 145,000 hours on the 50 hp QSI 235 which we bought used when we started in 1993.
The 100 hp Quincy and 75 hp Sullair compressors are water cooled units. The 50 hp Quincy compressor has an air cooled aftercooler. We really prefer the water cooled units in the summer months as they generate far less heat and produce a far superior quality dry compressed air. The water cooled compresors have the ability to cool the compressed air to within 15 degrees of the water temperature which is generally a constant 55 degrees in most areas. Thus, watercooled compressors have the ability to chill the air and squeeze far more water into a condensate form that can then be removed with the use of a good quality water separator.
Clean dry air is a must for all specialty blasting applications. Glass bead blasting can be especially tempermental if the air is not completely dry. Compressed air refrigerated driers are often used to accomplish the same task but they are expensive to buy and run, require high maintenance, and take up a substantial amount of floor space. In contrast, a water cooled compressor takes up the same amount of floor space as a conventional air cooled compressor but provides nearly the same quality cool and dry air as if it had been run thru a refrigerated dryer.
Air cooled compressors are generally used on smaller units like the 50 hp Quincy QSI 235 that we use. They are great in the winter when shop temperatures as generally kept around 68 degrees. They cool compressed air to within 15 degrees of ambient air temperatures which vary with the season. Air cooled units produce excellent quality air as long as dew points and temperatures are cool and dry. They also help recover heating costs where necessary and for the 9 months a year in Michigan, heat is generally required.
