SEEV-AHD Sumitomo's all-electric injection molding machine series takes advantage of new technologies to handle the larger, heavier and more complex molds that are usually reserved for hydraulics or hybrids. The eight mid-sized machines' clamping forces range from 242 to 562 tons. All machines in the series have an ejector stroke of 220mm.What's new? The series, which uses new technologies to reduce injection and clamping force requirements. Compared to earlier Sumitomo machines, the SEEV-AHD has increased tie bar spacing and expanded mold opening stroke, with the option of extending the mold thickness range by at least 100mm.
Benefits The precision, speed and energy-efficiency of using all-electric machines, combined with the power and capabilities of hydraulic machines to handle large molds. The machines' stronger, more rigid construction allows them to handle much heavier molds; on average, the SEEV-AHD presses can operate with 22 percent more mold weight than their predecessors. Also, the expanded tie bar spacing means that molds can be loaded from the side. Other benefits of the new technologies include faster open/close settings for the mold and clamp, more rapid cycle times and reduced downtime.
