Typically, hand extruders are divided into three types, which are different in their design: screw, without humorous and combined. If we talk about them briefly, then the non -mushrooms lose in the fact that they do not allow to achieve high pressure. This significantly narrows the scope of their application. The combined provides good mixing of the polymer, due to which they are extremely convenient when using composite material. The most popular type is a screw. He wins due to his axial effort, transmitting torque and better filling.
