CHICAGO (July 2, 8:50 a.m. EDT) — Nissei Plastic Industrial Co. Ltd. shipped its 90,000th machine in January, and the Japanese company took the “NEX” step at NPE 2003.
Nissei rolled out its new Elject NEX series of all-electric presses in a big way. Four of the eight injection molding presses on display at its booth were from the NEX line, which is replacing the Elject ES series of electric machines.
Masahiro Ueno, general manager of exports, said Nissei showed a single prototype of the NEX at last year's IPF show in Japan.
With four electric servomotors, the machines use a belt and ball screw to transmit circular motion of the motors to linear motion to run the press. The clamping forces run from 33-507 tons.
NEX machines will be available in the United States in October, said Ueno.
Nissei is targeting a range of markets, including automotive, packaging and medical. Its NPE demonstrations include cups from a six-cavity mold with a 3.4-second cycle, and a set of small utility cases. The NEX presses come in many options — 22 models with nine types of mold-clamping mechanisms and 13 types of injection units. Features include:
* Improved temperature control in the rear section of the barrel, including the feed section, through five temperature zones.
* Three types of injection specifications are provided — standard, high-speed and heavy-load.
* A new type of controller, called TACT, which Nissei said permits high-speed control of injection scanning time. The screen can be tilted to any angle for easier viewing.
* A new “flat clamp” mold clamping mechanism for high-cycle precision, thanks to a very rigid die plate.
Nissei also said the press is more energy-efficient.
In other machinery news at NPE, Nissei molded small, polypropylene dinner plates on a hydraulic-clamp AN1-series press in a new size — 197 tons. The cycle time is 5.5 seconds. A 306-ton AN1 ran a 16-cavity mold to make PP lids for potato chip cans on a 9.5-second cycle.
A robot-equipped, 171-ton, vertical-clamp press with horizontal injection insert molded automotive fan shrouds.
For micromolding fans, a press with just 3.3 tons of clamping force turned out tiny battery gaskets at Nissei's booth.
In business news, President Hozumi Yoda expects the company to sell about 3,200 presses this year — a 14 percent increase from the 2,805 sold in 2002. One big reason is Nissei's more aggressive effort to sell optical disc molding machines into China and other Asian nations, he said. The company also has improved the disc molds it is selling with the machines.
Yoda also said Nissei remains committed to assembling presses only in Japan — although the company has set up a subsidiary in Shanghai to handle spare parts and service. Nissei is sourcing some parts from China, such as castings, but Yoda said the company has no plans to follow other Japanese injection press makers that have set up assembly factories in China.
He said Nissei can control quality better with domestic assembly. It already is able to serve China with advanced-technology presses built in Japan, he added.
Nissei's 90,000th press was shipped to Polymatech Co. Ltd.'s plant in Fukushima, Japan, which makes parts for electronic equipment. Nissei is based in Nagano, Japan.
