Moulds with HR for moulding without a weld line

6 Moulds with HR for moulding without a weld line 

This group of nozzles includes nozzles with a side film gate which is cut-off in the closed mould after the end of the holding phase. Because the melt is relatively soft at the moment of truncation, the cutting vestige is almost invisible. 

After the end of the holding phase and removal of the injection machine nozzle, the springs (4) cause the bushing (2) with mandrel (3) to withdraw, and the gate is then cut off. The hole in the moulding is shaped using the pin (5).
