Types of Deep Drawing Processing
Drawing process: use the punching force of the flat plate device and the punch to pull part or all of the flat plate into the cavity of the female die to form a bottomed container.
Re-drawing: In order to increase the depth of the forming container, it is necessary to re-draw the finished products after drawing.
Reverse drawing process: reverse drawing the workpiece drawn in the previous process, then the inner part of the workpiece becomes the outer part, and the outer diameter becomes smaller.
Thinning and deep drawing: extrude the formed container into a concave cavity slightly smaller than the outer diameter of the container with a punch, so that the outer diameter of the container and the bottom becomes smaller.
