Our Company

"Dieter Rest" was founded in the year 1971. Today it is a highly innovative company for tool construction and steel punching. With a team of approximately 70 specialists, we are known for finding solutions for most challenging problems. We start where others gave up. From the design to the development; from the prototype construction to the series production, assembly and logistics − in this company you get certificated quality out of one hand.
The modern tape processing of different materials enables us to manufacture high-quality parts and components like e.g. drainage grates and collars for the sanitary sector and airbags fixations for the automotive sector. But also in sectors like air freight, food industry, agricultural machinery, sports weapons, heating manufacturing and many more, are continuously delivered from individual series to mass series.

The manufacturing of parts out of NE-metals and the automotive sector get more and more important. "Dieter Rest" is in almost every industrial sector the competent partner for further development − a partner who enables the series production within very short after the development. Throughout Europe more and more customers profit from our delivery reliability. Our aim is to provide excellent service at any time.

In June 2008 we moved to our new location in the industrial park Wiebelsheide, Arnsberg. We enlarged to an area of more than 4.000 square meters office, production and storage facility. The eye-catcher is our new 4.000 kN punching machine with patented Servo-technology.
