Long a proponent of "No hydraulic!," Niigata Machine Techno (Niigata, Japan) had a mission at IPF: to prove just what is possible with all-electric injection molding machines.
Long holding pressure not an issue with latest Niigata dithering technology.
In the vertical arena, Niigata's MDVR50X all-electric injection press boasts a tool-carrying capacity increased by 20% (to 200 kg for each mold half on the lower platen). Table rotational speed is at about 1.2 seconds per counterturn. This high speed rotation is realized by an air floating rotational table device. The table is lifted by air for friction-free and high-speed, smooth table rotation. By minimizing the friction wear, precision is maintained for extended periods.
A 150-tonne press has also been added to the MD-S6000 Series of all-electric presses, joining 100, 130, and 180-tonne presses. All machines in the series feature the Niigata's M-Support system on both platens to prevent tilting. The fixed platen tilt on the MD50S6000 after nozzle touch, for example, is one-tenth that of a conventional model. -[email protected]
