Introduction to Extrusion

Extruder Classification Extruders may be classified by three figures, for example, 1-60-24. The first number states how many screws the machine has, the second number specifies the screw diameter in millimeters (mm) and, the third number specifies the effective screw length as a multiple of the screw diameter. In the example

Turn the adjusting screw to the right to increase the pressure. Turn the adjusting screw to the left to decrease the pressure. Check the pressure by stitching on pieces of scrap material of the same weight. Note: A pressure that is too heavy will cause the machine to run hard and will leave the print of the feed on fine materials.
