HIGH OUTPUT AND HIGH PRECISION SEALS-QUALITY
Precision mandrel cutting machines for the production of aerosol and precision seals
We have developed our Metzner SR 85 especially for the production of high-precision flat profile gaskets and seals from molded or extruded hoses. The production principle is simple and very fast. It also delivers the best quality results with tolerances in the hundredths of a millimeter range.
An operator, who does not need to have any specific experience, pulls the cut-to-length hose pieces over the specially developed mandrels. The machine then automatically clamps the mandrels in the rotation axis. A knife carrier then moves along the hoses and produces the seals with the help of a circular or piercing knife. High-precision flat gaskets are cut wet on 7 mandrels at the same time, with size increments of 0.01 mm.
The Metzner SR 85 is therefore ideal for the production of high-precision seals, e.g. gasket manufacturers with high precision requirements, such as those used for the production of gaskets for aerosol packaging, heat seals, chemicals, petrol and gas gaskets.
