Nissei Plastic Industrial Co. has replaced its PS line of hydraulic injection presses with the new PN Series.
Nissei, based in Nagano, Japan, initially is offering the PN in two sizes, 40 and 60 tons of clamping force. The presses are aimed at high-precision molding, such as electronic parts.
Nissei gave the machines a new injection mechanism, including a new screw, heating cylinder and temperature controller. The machines also come with two kinds of hydraulic control systems, one that does digital servo control and the other to run hydraulic variable displacement pumps — which one is used depends on the type of parts being molded.
Nissei´s U.S. headquarters, Nissei America Inc., is in Anaheim, Calif.
