Development of key technology of coaxial twin screw extruder
The torque transfer mode between screw and mandrel is the key to realize the deep screw groove. The torque transfer between the screw element and the mandrel was initially connected by flat keys, which not only limited the deepening of the screw groove and increased the free volume of the screw, ...Read more -
Tube Plastic Extrusion Machine Process
Plastic extrusion of tube, hose and pipe is a steady-state process for converting a thermoplastic raw material to a finished or near-finished annular product. The raw material is usually in the form of plastic pellets or powder. The conversion takes place by forming a homogeneous molten mass in t...Read more
