Milacron Holdings Corp. has added several enhancements to its E-Multi line of all-electric, servomotor-driven, mold- or platen-mounted, mobile auxiliary injection units for multi-material or multi-colored applications. The units are not brand-dependent, and therefore can be used with a Milacron injection molding machine or with a machine made by another manufacturer. The line includes four core models: the EM1, EM2, EM3 and EM4.

The mold-mounted E-Multi EM1 features a new carriage that provides enhanced utility and a compact fit of the unit into the molding area. It also has a relocated spring pack to provide increased tie-bar clearance and increased mechanical nozzle protrusion adjustment from ±5 to ±15 mm. EM1 and EM2 mold-mounted models with servo carriages are designed for applications requiring sprue break (the ability to retract the nozzle each cycle away from the melt inlet). This allows these models to be utilized for applications where injection at the parting line is required or in applications where the melt inlet moves relative to where the secondary injection unit is located

The larger E-Multi EM3 and EM4 models are now capable of being outfitted with a radial option that allows the units to mount to the top of the stationary platen and rotate to a “parked” position, providing unobstructed access to the mold mounting face for quick mold change. Servo sprue break motion is standard. The EM3 and EM4 units are capable of shots of 57 to 499 cc.
