Nissei Shows a Variety of Energy-Saving Presses
Nissei of Japan brings its latest all-electric and servo-hydraulic injection machines to NPE.
Among seven machines on display by Nissei Plastic Industrial Co. of Japan will be examples of two new lines. One is the servo-hydraulic FNX-IV series with the new TACT 5 controller. This new generation boasts “best-in-class” tiebar spacing and 100 mm greater daylight. Thanks to the ample mold area and the company’s latest N-SAPLI low-pressure molding technology, the container mold running at the show in a 237-ton model would normally require a 386-tonner, Nissei says.
The new control is designed for the “upcoming Industry 4.0 era”—it is reportedly compatible with communications standard for the IoT (“internet-of-things”) enabled factory and it collects and analyzes quality and production management data.
Also new is the next-generation NEX-IV all-electric range from 33 to 397 tons. It has “one of the widest daylights in the industry” as well as the industry’s smallest footprint, Nissei claims. It has 100-mm longer daylight and a new toggle with linear guides that cuts mold open/close times by 5 to 20 percent. The company’s “New Flat Clamp Mechanism” is said to improve the evenness of clamp pressure and prolong mold life. This machine also demonstrates Nissei’s “Precision Metering” function, which maintains consistent shot volume and density.
A 397-ton NEX-IV all-electric press is molding a pair of drinking mugs with IML. A 121-ton machine in this family is part of a two-component molding cell that teams up two presses to mold a magnifier. First, the NEX-IV machine molds the thermoplastic casing, and then a robot passes the part to a FNX-II hybrid (123 tons) to overmold the LSR lens.
Other Nissei exhibits include a 7.8-ton NPX7 servo-hydraulic micromolder, a 501-ton, servo-hydraulic FNX-III machine with TACT IV controller, and a 22-ton STX Series servo-hydraulic, vertical insert molder with servo-driven turntable, fast injection (300 mm/sec), and two-arm SCARA robot.
Showing that Industry 4.0 is not just a European or American phenomenon, Nissei will demonstrate its “Visualization of Factory” program for using the injection machine to collect not only mold and material data, but pull information from all connected devices, such as auxiliary equipment and the factory environment. An element of this system is the “PQ Manager,” a quality- and production-management system that can monitor multiple machines.
“Revolutionary” screw design turns conventional plastication theory upside down.
Molded parts barely visible to the naked eye require non-traditional methods for making high-precision micro-injection molds. Micro-tooling R&D is being led by technology institutes, research firms, and a few highly specialized mold makers.
Next month’s mammoth triennial plastics show in Düsseldorf, Germany, challenges injection molding machine builders to demonstrate technological leadership in addressing the needs of the marketplace.
