Deep drawing is a cold stamping process of using punch and die to make a sheet blank or a semi-finished blank into an opening hollow piece part. The geometries of products made by deep drawing include cylinder, stepped, domed, tapered, rectangle, and irregular shape. The combined fabrication process of deep drawing and stamping can make the shape of products more complicated, for example, compound die of combining blanking and deep drawing. CFTC is on the progress to develop this know-how and technology. |
