Material: high quality alloy steel 38CrMoAlA
Screw length-diameter ratio generally tends to be larger, more than 32 ratio, which can ensure enough extrusion pressure and plasticization degree. The screw structure is roughly divided into three sections plus mixing head. But we also can design screw structure according to customers’ needs.
For raw material impurities, our company can provide exhaust screw barrel, so that the gas impurities can be exhausted from the exhaust port to ensure the smoothness of products. In addition, the drying process is avoided.
