Milacron Holdings Corp. (Cincinnati, OH), an industrial technology company serving the plastics processing industry, announced that Mold-Masters, the company's hot-runner brand, has developed several enhancements to the E-Multi auxiliary injection unit.
The E-Multi is an all-electric, servomotor-driven, mold- or platen-mounted, fully mobile auxiliary injection unit for multi-material or multi colored applications. The E-Multi is designed for molders who are looking to economically optimize their existing injection molding machine assets with an auxiliary injection unit that is mobile, compact and footprint neutral, said Milacron's information.
Milacron Global Product Manager, E-Multi, Yann Coquelle stated: "The E-Multi maximizes the injection molding performance and allows molders to enter into the growing multi-material and multi colored applications market by leveraging the simplicity, precision and cost efficiency of the E-Multi."
Coquelle went on to note the versatility of the unit: "The E-Multi is not brand dependent. It can be purchased alongside a Milacron injection molding machine or separately to be used on a molder's existing injection molding machine, regardless of the manufacturer."
The mold-mounted E-Multi EM1 model has received a new carriage that provides enhanced utility and a compact fit into the molding area. Along with the new carriage, the EM1 has a relocated spring pack to provide increased tie-bar clearance and mechanical nozzle protrusion adjustment from ±5 to ±15 mm.
The new E-Multi EM1 and EM2 mold-mounted models with servo carriage are designed for applications requiring sprue break (the ability to retract the nozzle each cycle away from the melt inlet). This allows them to be used in applications where injection at the parting line is required or 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, which mounts to the top of the stationary platen and allows the E-Multi unit to rotate to the "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 from 57 to 499 cc.
Additionally, the latest version of the E-Multi software (V1.34) has been released and is shipping on all new E-Multi systems. It includes 68 new features and enhancements. With the E-Multi software update comes the ability to integrate a Milacron Varian rotary table and have it controlled through the E-Multi control cabinet.
