... then heated and stretched over the pattern. Small vent holes in the pattern, the pattern board, and also the hollow construction of the pattern carrier allow a moderate vacuum (27 to 53 kPa, or 200 to 400 torr) to be applied to the pattern. This draws the plastic film tightly to the pattern ( Fig. 4...

In drawing long and small-diameter tubes, the plug bar may stretch and even break. In such cases, it is advantageous to use a floating...
