Burn-off Cleaning, also known as Heat Cleaning, is the method of removing unwanted coatings from steel parts by heating the parts in an oven. National Peening, Salem is permitted by the state of Virginia to operate ovens specially designed for this process. Heat from the oven breaks down the unwanted coatings and forces them off the work pieces in the form of smoke. The smoke is consumed in an afterburner. The only thing that exits our exhaust stacks is hot air. The ovens used at National Peening, Salem are the highest efficiency models available. Our ovens automatically monitor the progress of each oven cycle. When the unwanted coating is eliminated, the cycle ends and shuts down the oven. No operator intervention is required to determine cycle times. Parts holding fixtures from high volume production painting and powder coating operations have need for this service. Burn-off cleaning is environmentally friendly as well as economical.
