The surfaces of the die castings are machined especially by grinding at the roboting workplace with the rotatory holder with the grinding unit produced by DAN TECHNOLOGY equipped by robot KAWASAKI. This grinding unit allows to set up constant pressure of the die casting, which provides a high stability of grinding process considering the grinded form of the die casting.

DOR company also has got own painting shop. The die casting made of aluminium and also zinc alloys are being painted by electro kinetic process of powder application and are thereafter burned out in the electric furnaces. On this way are being treated especially decorative parts but this process sis also used for anticorrosive protection of the parts which are left open to weather.
