1、Using the system to draw piping figure, can enhance far and away drawing velocity .
2、Data of drawing velocity that is automatically measured by precise extrusion were analyzed.
3、The effects of processing parameters, including mold temperature, cooling distance, drawing velocity and spraying cooling intensity, on the solid-liquid surface position of the billet were calculated.
4、The effects of spinning temperature, spinning pressure and drawing velocity on the degree of profile and effective diameter of the fibers were studied and the preparation technology was determined.
5、In addition, the decline of the temperature, the raise of the drawing velocity, the raise of the friction coefficient all could lead to the increase of the maximum stroke force.
