Thermal stripping, or thermal cleaning, is a process whereby metal parts undergo thermal pyrolysis and oxidation simultaneously at an extremely high temperature in a controlled environment, ensuring parts do not deform when heated.
At Northpoint, the thermal stripping process is undertaken in a fluidised bed system, utilising sand heated to temperatures between 340 to 510 °C and taking an average of between one and two hours. Our facility has the capability to strip parts up to 3700 x 500 x 1500mm.
Alongside the main bed are two smaller pyrolysis ovens that can reach temperatures of up to 600 °C internally, which remove or break down the organic coatings. By heating the parts in a reduced oxygen atmosphere, a reaction takes place and reduces the coating to a residue that can be easily removed. Any emissions that are given off during this process are put through an afterburner, which burns the gasses at 850 °C per second and converts them into H2O and CO2.
Thermal stripping is suitable for heavier, more complex metal parts, where blast cleaning would not be economical. It provides a cost-effective method of stripping existing paint coatings, and an environmentally friendly solution to reusing and recycling metal parts. Once stripped, the metal part has a smooth, clean base, meaning the powder coating application will be more effective, creating a more polished look and ensuring the longevity of the new powder coating.
