Schematic of ejection timing with added MO time
Multi-Cavity Molds Especially with multi-cavity molds, it may not be possible to clear all molded pieces out of the molding area in time and some MO time will have to be added. The need for this MO time should be closely scrutinized; while it is sometimes not possible to avoid MO time, it is quite common that the setup persons add extra MO time “just to be sure” that the pieces have cleared, rather than to ensure that the ejection, including air assist, is properly adjusted and timed as intended. ...
