All-Electric IMM Advances for Packaging, Medical and LSR
NPE2024: Sumitomo SHI Demag’s show focus is on the application of all-electric injection molding machine technology for a variety of markets and components.
Sumitomo SHI Demag says that, under a theme of sustainability and efficiency, its NPE2024 booth exclusively features its all-electric machinery lineup, showcasing a range of sizes and capabilities.
Attendees can see Sumitomo’s all-electric machines, as well as its automation offerings, in action across various industries, including packaging, medical and LSR molding. In packaging, the PAC-E machine features an injection unit specifically designed for beverage closures and thin-wall packaging with injection speeds of 550 mm/sec. Developed in Germany, its toggle levers, platens, tie bars and plasticizing elements (including screws and cylinders) are geared for precision. The Japanese-designed electric drives and injection unit promise energy efficiency, requiring about 50% less energy than hydraulic models. At the show, the machine will run a 72-cavity water bottle cap mold, producing 5 million caps during the week of the show.
In medical, a SE130EV-S SHR machine, featuring enhanced injection unit capabilities for thin-wall and high-precision applications with increased acceleration and deceleration, is on display. The machine, which achieves injection speeds up 1,000mm/sec, is paired with an ISO Class 7 pipette automation system that handles part removal and inspection.
In LSR, Sumitomo (SHI) Demag introduces its SE-EV-A machine with a built-in dosing unit and mold temperature control for greater regulation of the injection molding process. A 130-ton SE-EV-A is running a 15-cavity fully automatic piston mold with an 8-drop valve-gate cold runner tool from M.R. Mold & Engineering. Material is Shin Etsu’s KEG2003H-50 with a Kri Color additive, and automation comes from Yushin with its FRA-1530S/D/DS all-axis servo driven robot. Nexus is supplying the metering system, with a Frigel chiller. The company is also highlighting SAM (Sumitomo. Automated. Machines.) Robots are prevalent throughout the company’s booth, including its new SAM product line paired with its IntElect injection molding machine in a complete exhibit. SAM robots offer low-maintenance automation that’s capable of handling quick, repetitive tasks or being tailored for complex, customized applications.
