Automobile manufacturers and tier one suppliers rely on Menzerna to continuously adapt polishing processes to changing coating technologies and to improve productivity.

Automobile Interior

Requirements:

minimise manual reworking
avoid overheating of clearcoats through frictional heat during the polishing operation
reduce number of sanding operations before polishing. Grid 320 sanding marks have to be eliminated without compromising the surface quality of the finished product

Decorative Aluminium Parts

Requirements:

compound residues must be easy to remove in water based degreasing baths. Residues on polished parts have to be minimised in order to prolong the operating life of the degreasing bath and to avoid carryover into the galvanic baths
minimise the risk of spontaneous combustion of polishing waste
avoid overheating of aluminium parts through frictional heat during the polishing operation

Clearcoats

Requirements:

grid 2500 - 3000 sanding marks have to be eliminated on all types of clearcoats without leaving haze or holograms.
dust formation from polishing minerals set free during the polishing operation has to be limited in order to avoid contamination of the coating process
standard times for the elimination of paint defects have to be met in order to ensure a smooth production flow
Polish formulations have to be kept abreast of new coating systems and demanding perfomance standards of OEM manufacturers (see case study... )
