Nissei Plastic Industrial Co. Ltd. developed a new hybrid vertical injection molding machine that the company says offers one of the industry’s lowest machine heights with a clamping force of 220 tons.
Nissei began accepting orders May 1 for the TNX220RIII25V.
The machine was developed from the hybrid Nissei vertical press, the TNX-RIII Series, widely used in industries such automotive and electronics. The new press is equipped with a new compound-type clamping mechanism and boasts low-profile structures throughout the machine.
The clamping mechanism consists of a high-speed cylinder, high-pressure clamping cylinder and a half-nut mechanism, which replace a conventional type cylinder that controls both high-speed clamping and high-pressure clamping with a single cylinder. Nissei said that, because of this new mechanism, the mold mounting height is lowered to 30 inches, about 30 percent lower than conventional vertical presses. The overall machine height is about 10 percent lower.
In other features, the hybrid vertical is equipped with a direct-pressure type clamping mechanism that evenly transmits the clamping force. Also, the amount of hydraulic oil is reduced by 52 percent, thanks to the new compound-type clamping mechanism.
The machine’s bed structure permits flexible layout of robots. It can easily be adapted into using takeout robots, articulating-arm robots and two-arm robots.
A three tie-bar wide turntable, and large maximum daylight accommodate larger and more complex molds. Turntable rotation and ejector motion are driven by servomotor, for fast, smooth and precise movement.
The press has Nissei’s TACT IV controller.
