How to know the part structure and function of screws.

The functions of the screw are all composed of different part structures, from the feeding to the final extrusion of the screw, for example, reverse flow screw grooves, feeding zone, pre plasticizing, mixing plasticizing, choke compression, exhaust, establishment of extrusion pressure and extrusion zone, etc There are 5-10 sections of screws in general way .

To understand these different structures, an easy way is to select a screw that you are familiar with as the standard, confirm the structure and performance characteristics of the screw, and then compare the efficiency and difference of the partd structure according to the change of the part structure

Through repeated, you will be familiar with the part structure and function of screws
