Hannover, Germany - KraussMaffei Berstorff has installed a new rubber profile production line in its technical center in Hannover. The state-of-the-art extrusion line features different vulcanization systems, shock modules, microwave and hot-air channels. The extruder unit is a Vac GE 90 KSL x 20 D powered by a water-cooled three-phase motor.
The 1.5 kW magnetron units of the microwave channel are continuously adjustable. A circulator integrated into the energy supply transfers the energy that is not absorbed by the product to the connected water load, which results in longer magnetron service life.
Each of the three modules is equipped with four 1.5 kW magnetrons, i.e. each module supplies a magnetron power of 6 kW. This channel features a total installed magnetron power of 18 kW. The microwave generators are arranged above and below the conveyor belt. The design of the microwave coupling system ensures extremely homogeneous field distribution. Both the microwave power and the conveyor belt speed can be continuously adjusted. The microwave line features an effective cross section of 150 mm width and 75 mm height.
With this modular line, sophisticated sealing profiles for the automotive and building industries can be produced in a single working cycleâ€œ, explains Harald Hepke, Head of Rubber Technology at Hannover-based KraussMaffei Berstorff.
