Nissei Plastic Industrial Co. Ltd. reduced the price of an 860-ton injection molding machine by 30 percent. Nissei showed the machine, model FV9200, at IPF '96, held Oct. 11-15 in Chiba, Japan.

Nissei said it reduced the price by rethinking which machine functions are necessary, followed by a ``severe review and reassessment of all relevant costs.'' The company made major changes in both the injection and mold clamping mechanisms of the machine.

The FV9200 uses a rotary ram injection system that has a larger ratio between the injection stroke and screw diameter than a conventional machine. Nissei said that feature gives a better response and more precision, so the company can use a compact injection mechanism. At the same time, the diameter of the piston rod is about three times as large, giving mechanical stability, according to Nissei.

The mold clamping area has a larger daylight between the platens. Also, mold opening/closing speed is 25 percent faster.

The firm also showed an electric machine called the ES Series. One machine, a 360-tonner, is the largest ever made in Japan, Nissei said.

Other horizontal machines had clamping force of 180 tons and 40 tons. A vertical electric press also was shown.

In addition, Nissei exhibited a 180-ton, high-speed FC4000 press for molding thin-wall containers and food packages. The Nagano, Japan, company also showed a DVD molding machine.

Nissei's U.S. unit, Nissei America Inc., is based in Anaheim, Calif.
