production process - compression-moulding
First the raw material is cut into small form parts with a weight
according to material quantity needed to fill the mould. Then it is
pressed with hydraulic presses. The heat which is needed for the
vulcanization process is applied through the pressing mould. The time
which is needed to achieve the vulcanization of the product depends on
materials and temperature of the mould.
production process - transfer-moulding
The transfer molding process is similar to the injection molding. The
raw material is placed into the preheated mould. While closing the
press the material is „injected“ through channels into the molding
nests.
production process - injection-moulding
Injection molding is made on special injection molding machines.
The material is molded inside a special piston which plastifies and
tempers during this process. The main advantages are reduced
vulcanization cycles through even warm caouthchouc material and very
high accuracy on measurements.
