Slitting rubber is a special challenge, as the application range of the rubber material varies widely, e. g. tire production, diaphragms, conveyor belts etc., and some rubber materials are equipped with inserts (e. g. steel cord and Kevlar).
The main criterion that both the crush and the shear cut system have to meet is the required slitting force which creates a flawless cutting operation. Our crush cut knives PQAS / PQDS with multiple cylinders meet all these requirements. For the shear cut system, collars and bottom knives mounted on top and bottom knife shafts are suitable. With this system, very narrow slit widths are possible.

The plastics industry owes its strong growth to the numerous innovations in the area of polymer chemistry up to this date. Our daily life is greatly influenced by plastic materials due to their physical properties and versatile application possibilities.
DIENES slitting tools are worldwide applied for processing and cutting to size the wide variety of plastic materials. While razor blades are applied for cutting thin materials, for thicker materials, the shear cut system is applied. In special cases the rotary shear system may be suitable.
Independent from the slitting system to be used, DIENES is your competent partner when it comes to slitting plastic materials.
