Sumitomo (SHI) Demag Plastics Machinery will introduce its SE-EV-HD all-electric injection press to the North American market at NPE 2015.
HD stands for heavy duty. The presses, part of Sumitomo Demag's flagship SE-EV Series, are designed to mold thicker-walled parts, including complex parts with a combination of thin and thick walls.
The NPE show press has a clamping force of 202 tons. Other sizes for the series include 112 and 146 tons.
The SE-EV-HD can provide full pressure for up to 40 percent of the molding cycle, and maintain exceptional stability, company officials said. It is ideally suited for parts with cycle times of 15 seconds and longer — applications ranging from automotive to appliance and consumer products.
“Sumitomo (SHI) Demag's unique capabilities in advanced motor technology have enabled us to expand the high-speed SE-EV Series with an HP model for ultra-high speed applications requiring injection speeds up to 1,000 millimeters per second, and now with an HD model that meets the need for longer and higher pack-and-hold pressures,” said John Martich III, vice president and chief operating officer of Sumitomo Demag's U.S. operations in Strongsville, Ohio.
Features include the company's Flow Front Control (FFC) system that takes advantage of the energy in the flow front of the resin to complete filling in an even fashion. A Minimum Clamping Molding (MCM) system allows the press to automatically detect the minimum point when the mold halves are completely parallel, and defines the threshold where flash-free molding can occur, and the optimum point for the best cavity venting.
The Simple Process Setup (SPS) gives an easy setup, operation and machine optimization.
