HIGH OUTPUT AND BEST QUALITY
Precision mandrel cutting machines for the production of plain section gaskets
We have developed the precision machines of our Metzner SR series especially for the production of sealing rings from moulded or extruded hoses. The production principle is simple, fast and gives the best quality results.
An operator with no previous experience simply and quickly pulls cut-to-length rubber tubes or hoses onto the specially developed mandrels. Than the machine clampes the mandrels automatically between rotating spindles. A knife carriage travels along the tubes and produces the gaskets with the help of a circular knife or a tap knife. You can choose between two models, one for maximum 170 mm outer diameter of the tubes, the other for up to 200 mm outer diameter.
