Extrusion Process

For faultless and uniform distribution of plastified material in the area of screen plate, the screw geometry, the die inlet and die bore are optimized from the Reheological point of view, so that there cannot occur any thermic damage of product in the region. The design is based on the concept of a very low velocity of extrusion through each hole, in order to have low head pressure. This means a thin pellet plate, which also keeps the pressures low. The low pressure in the head allows better control of the polymer’s temperature.
