Injection speeds as high as 1000 mm/sec are possible with the new CH 450 AC electric servo injection unit from Toyo Machinery & Metal Co. of Japan, represented here by Maruka U.S.A. Inc., Rockaway, N.J. The new injector for Toyo’s all-electric Si-III models of 100 and 130 metric tons uses a “triple high-powered” AC servo-motor and belt drive. It has 0.0185-sec acceleration time and max. injection rate of 452 cc/sec. A new 15-metric-ton high-speed model has been added to the Si-III series. The new Si-15 III has a max. injection speed of 500 mm/sec and acceleration time of 0.009 sec. Other features include a highly rigid toggle clamp. Toyo’s Si-350 III H model for fast-cycle molding has even faster clamping due to the use of low-inertia twin-drive motors. The unit has an open/close dry-cycle time of 1 sec with a 160-mm stroke.
