Which manufacturing processes can be used to produce flat gaskets at Rehm Dichtungen?

For the production of your individual flat gaskets, we can rely on different manufacturing processes - waterjet cutting, plotting and punching.

For initial samples up to small series, we cut your seals with the help of our plotters. Our die-cutting production process is particularly recommended for regularly recurring requirements with a medium quantity. If your gaskets exceed the standardised plate size, we rely on our expertise in industrial handwork to turn your wishes into reality.
