Dry/wet sandblasting, sandblasting and finishing parts

For paint to adhere properly to the painted component, it must be cleaned thoroughly and free of rust and production residues. We achieve this through finishing. During the finishing process, the product is descaled, deburred, cleaned, polished, degreased, and dried.

We use several machines to finish products in our cleaning plant. The first of them is the OS 1A-4A tumbling drum, where we clean components with a maximum weight of 190 kg. But we also have a circular vibrating tumbler R 260 Euro, which can hold semi-finished products weighing up to 375 kg. We also use a circular dryer RT 250 Euro with a maximum batch weight of 40 kg.

Another important surface pre-treatment before painting is metal blasting. Thanks to this, the workpiece surface is beautifully cleaned, roughened, unified, and further treated. We use various abrasives to blast the workpiece, such as glass balls, white corundum, or ceramics. Each has a different use due to its properties.

The processed component’s dry sandblasting takes place under pressure in sandblasting cabinets. In addition to standard sandblasters for dry sandblasting, as one of two companies in the Czech Republic, CENTES has professional sandblasters for wet sandblasting, which create an amazingly smooth surface.
