High quality intermediate sanding after priming of panels is key to achieve the perfect final lacquer finish. Unfortunately, this step in the sanding process generates large amounts of fine sanding dust. These fine dust particles are similar in size to the “grooves” created by sanding and therefore remain tightly wedged in these grooves, so require a great deal of effort to efficiently remove them from the surface.

As a rule, sanding machines are equipped at the out-feed with various dust extraction methods, such as compressed air jets or vacuum devices, that can often prove ineffective and, therefore, large quantities of fine dust still remain firmly attached to the surface. Wiping the supposedly clean surfaces with a microfibre cloth finds evidence of residual fine dust. Even brush cleaning applications frequently fall short when confronted with the large amounts of fine dust created. Brushes are literally suffocated with fine dust accumulating on the surfaces of the filaments and clogging up the brushes. As any person who has ever tried to sweep snow with a broom will be well aware, after a very short time, the spaces between the bristles fill with snow and the broom slides over the snow instead of sweeping it up!

Wandres have developed a modular cleaning unit combing ventilation technology and brush cleaning has passed the test with flying colours in continuous industrial panel production. A process combining Tornado Channel and Sword Brush can significantly reduce reject rates arising from the appearance of particles in the lacquer coat. As a result, finer coats can be applied which has a positive effect on the quality of the surface finish, in particular where surfaces require a mirrorlike high gloss finish. A positive knock-on effect of this system means that the amount of coating product required is minimized, thereby lowering paint costs, machine downtime is cut and concentrations of fine particulate matter in the production area is reduced, which also improves workplace health and safety standards. The combination of Tornado Channel and Sword Brush systems deliver cutting-edge cleaning technology for the cost-efficient and replicable mass production of high gloss furniture panels with a superior surface finish.
