Body-in-white refers to the process in car manufacturing in which the body shell is joined together before painting. This is done using various methods such as welding, riveting or laser soldering. If defects are not detected and eliminated during this process, the painting processes can exacerbate the defects or cause paint defects.

The sanding process consists of two critical processing steps: coarse sanding and fine sanding.

Coarse sanding: smoothing out imperfections and burrs, removing or smoothing noses or protruding welds.
Fine sanding: finishing of the coarsely sanded areas and removal of minor defects (above or below the surface) caused by punching or machining.

Defects are usually found on hoods, roofs, doors, mudguards and trunk lids.

In order to achieve the desired surface quality in each of these processing steps and to optimally prepare the body shell for painting, the selection of the right sanding tool is crucial. From fiber discs, flap discs, flap sanding rotors, brushes and non-woven products for coarse sanding to paper, film and mesh discs for finishing, we offer the right solution for every process.
