The lower part of the press is equipped with a forging ejection device. Screw press has the function of many kinds of forging machinery, such as die forging hammer, mechanical press, etc. It has strong versatility and can be used in die forging, blanking, drawing and other processes. In addition, the screw press is widely used because of its simple structure and easy manufacturing.

The screw press has no fixed lower dead center. For larger die forgings, it can be formed by multiple blows, and can be single hit, continuous hit and inching. The striking force is related to the deformation of the workpiece. When the deformation is large, the striking force is small, and when the deformation is small (such as cold stroke), the striking force is large. In these respects, it is similar to a forging hammer. However, its striking force is closed by the frame, so it works stably. Its vibration is much smaller than that of the forging hammer, and it does not require a large foundation.
