A new 135-ton hybrid injection blow molding (IBM) machine, which offers up to 35% energy saving compared with conventional hydraulically powered machines has been introduced by Jomar Corporation, a specialist in blow molding machinery. The size of the maim pump motor has been reduced by separating intermittent extruder drive demands from continuous demand clamping and auxiliary systems. The hybrids feature a 30-hp hydraulic system with an electrically driven extruder unit that replaces a 100-hp drive, and that is dedicated exclusively to clamping. The machine footprint is reduced by using a vertically oriented, pressure-balanced, electric extruder drive. That eliminates the need for large thrust-bearing housings and coupling components.
