Why We Have To Cool The Bimetallic Barrel Screw? Jul 27, 2018

When extruding the material, it is necessary to cool the bimetallic barrel screw, mainly to ensure smooth production and prevent the material from decomposing due to excessive plasticizing temperature. For example, in the feeding section of the bimetal barrel screw, it is to prevent the screw temperature in this section from being too high, to avoid the material being attached to the screw thread groove of the screw due to the high temperature, which affects the material conveying forward, resulting in insufficient feeding. It cannot be produced normally.
