Robot significantly reduces production time of large moulds

The arrival of machine hammer peening opens the way to fast finishing of large milled injection and deep drawing moulds. Instead of manual polishing, an industrial robot does the work in a shorter time. This process also offers a number of other advantages.

Milled moulds are traditionally polished manually. A labour-intensive job that, especially with complex pieces, can take up to 20 man-days. Moreover, the quality of finishing is not always the same. German engineering company Sematek, in cooperation with 3S Engineering and robot builder KUKA, has developed a new finishing method, aimed to achieve a production time reduction of 60 percent. By means of a CNC robot the surface of moulds can be smoothed in a relatively short period of time. The process is flexible, precise, reliable and cost-efficient.
