Explaination of The Drawing Process:
1) First, we start off with a coil of raw material.
2) The material is fed into our high speed transfer press
3) The machine stamps out a Blank
4) The Blank is then transferred into the cup operation as seen here
5) The Blank Holder applies even pressure on the Blank as the Cup Punch Draws the material into the Cup Die thus eliminating wrinkles in the Cup.
6) The Cup is then transferred into the First Draw Operation where it is drawn to the correct Inner Diameter, Outer Diameter, and Over All Length.
7) Next, the shell is transferred into the Pierce Operation where the specified dimension of material in the bottom of the shell is removed.
8) Finally, the shell is transferred into the Clip Operation where the excess material will be removed leaving you with a perfectly finished product.
