Mold knife edge

Generally, in large volume production, pinch-off inserts are made of steel (P-20 or S-7) with the other portions of the blow mold produced from a nonfer-rous metal. The pinch-off edge should not be similar to a knife edge, or it will tend to act as a cutter and will yield a V groove where the tail or pinch-off area of the parison is forced to bond. Fig. 13.20 depicts a poor weld line due to the pinch-off having a knife edge. [Pg.277]

The nanoscale structure of PBA-SS was investigated by means of TEM (Hitachi H-700 instrument), operated at an accelerating voltage of 100 kV. An ultrathin section (the edge of the sample sheet perpendicular to the compression mold) obtained using a diamond knife with a thickness of lOOnm was micro-tomed at 80 °C. [Pg.127]
