Thin-walled parts are the target of a new all-electric model featuring high speed, high acceleration, and high-pressure capability, coupled with a high-response control. The 110-ton Roboshot S-2000i100Bh was introduced at the International Plastics Fair in Tokyo in November by Fanuc Ltd. of Japan, (represented here by Milacron Inc., Batavia, Ohio). It delivers injection speeds of 1000 mm/sec with a response time of 0.33 sec. The press can mold products up to 0.35 mm thick. A standard S-2000i100B model has 200 mm/sec max. injection speed, with options for 330 or 500 mm/sec. The new model employs a direct-drive, high-power servo motor rather than a belt drive, and delivers 1.9 times greater acceleration (3.6G) than the 500-mm/sec design. It uses a screw smaller than the standard 40-mm diam. The unit also has a more rigid, two-piece stationary platen to minimize flash. The new FFF controller runs Fanuc’s FFF software, which increases injection acceleration instantaneously; and its HR program, which enables selection of the optimal injection-to-pack-pressure response. A “high filling mode” enables a temporary increase in maximum injection pressure. (513) 536-2000 • www.milacron.com
