Metzner Dynamat Series
High-Performance Impact Cutting Machines for Maximum Cycle Rates
Optimized for material dimensions up to 20 mm at extremely high cycle rates, ideal for efficient mass-production cutting.
Specifically engineered for processing elastomer hoses without stretching or crushing – directly in the extrusion line or in stand-alone operation.
Enclosed cutting chamber with micro-blade lubrication ensures clean, rectangular cut edges and protects the operator during high-speed operation.
Designed for large material cross-sections up to 80 mm in diameter, without compromising on cut quality or length accuracy.
The ideal solution for demanding applications such as fabric-reinforced pneumatic hoses or technical plastics where maximum throughput is required.
The closed work area allows for either dry or wet cutting, minimizing frictional heat and preventing sticking or fraying even with challenging rubber compounds.
Hose Cutting at Maximum Speed
Maximum Productivity in High-Volume Cutting
Hoses fulfill key functions in modern industrial and automotive applications, including conduit, protection, and insulation. The quality and quantity requirements in manufacturing are correspondingly high. Dynamat impact cutting machines were specifically designed to handle enormous volumes of material while ensuring full process reliability.
Thanks to the combination of a dynamic cutting principle and sophisticated feed technology, they process rubber and elastomer hoses without stretching or crushing them – either directly on the extrusion line or in stand-alone operation.
Perfect cutting results thanks to a sealed cutting chamber and micro-lubrication
Certain elastomers are prone to generating frictional heat, sticking, or fraying during the cutting process. The machines in the Dynamat series therefore operate within a fully enclosed working chamber. This not only protects the operator during high-speed operation but also allows for either dry or wet cutting.
The standard micro-blade lubrication system cools and lubricates the blade in minimal doses, reduces friction to a minimum, and guarantees right-angled, clean cut edges even with challenging rubber compounds.
Wherever hoses and profiles need to be cut to size in large production runs and with extremely short cycle times, the Dynamat series sets the benchmark. Whether it’s elastic rubber, synthetic rubber, fabric-reinforced pneumatic hoses, or engineering plastics: Metzner Dynamat slitting machines combine maximum throughput with uncompromising cut quality and length accuracy – both in continuous post-extrusion processing and from a coil.
Large volumes of material with full process reliability
Fly knife cut
Precision for Every Hose Size
The Dynamat series sets new standards in high-speed hose cutting: With cycle rates of up to 2,000 cuts per minute – which can be further increased using multiple blades if needed – it processes hoses and profiles up to 80 mm in diameter in record time. Whether in precise “stop-and-go” operation or continuous cutting: Length measurement via a measuring wheel or synchronous trailing measurement directly at the extruder (available as an option) ensures maximum repeatability at all times.
Thanks to the enclosed safety work area and the integrated micro-blade lubrication system, clean wet and dry cuts can be performed reliably at all times. In combination with optimized cutting geometries, users benefit from exceptionally long blade life, minimized downtime, and consistently cost-effective production cycles.
