Metzner SR-Series: Flat Gasket Cutting Machine

Metzner has developed the mandrel cutting machines of the SR series for cutting off sealing rings from injection-moulded or extruded tubes with different diameters. These machines are characterised by their unique processing method and high cutting quality. First, pre-extended "rubber tubes" are clamped onto mandrels. Due to the special design of the mandrels, the mandrel can be set up and removed quickly and without special previous knowledge. The mandrels are then automatically clamped in the machine between rotating spindles and production is started. A knife carriage travels along the tubes and cuts the flat sealing rings to the desired length with either push-fit or circular knives, depending on the requirements. This cutting method is particularly impressive with its high cutting quality in combination with a high output. 

Thanks to the use of state-of-the-art servo technology, the SR machines are even more versatile: Insertion and feed movements are freely programmable – for optimised processing of materials with different material properties. The SR series ranges from two- to seven-strand machines. Metzner therefore offers the most economical solution for different capacity requirements.

Precise and high-performance

Metzner mandrel cutting machines of the SR series are ideally suited for the precision cutting of gaskets from injection-moulded or extruded tubes. They are characterised by the possibility of processing up to seven tubes simultaneously. Our product videos will give you an insight into the machining process.
