Japanese Nishiuchi Seisakusho developed the Floating Self-Centering Mold System

November 16/2011

(PlasticsToday) -- Japanese toolmaker Nishiuchi Seisakusho (Kiryu) developed what it calls the Floating Self-Centering Mold System that does away with guide pins altogether, while enabling the molding of precision components such as connectors with wall thickness down to 0.09 mm and core hole width of 0.12 mm.

Explaining the concept of the system at the recent IPF show, Nishiuchi Seisakusho CEO Kenji Nishiuchi presented a marker pen and repeatedly took off the cap and placed it back on. "Essentially, that's what's happening when the our tool opens and closes, and it does so with precision of 0.5 micrometers," he says. "The cavity half  on the moving platen is attached via rigid springs and this enables it to mate perfectly with the half on the fixed platen during clamping," says Nishiuchi.

Perspectives of development of polymer markets, pricing issues and other important aspects will be discussed at The Polymers Summit-2011, which will be held in Moscow on November 30, 2011 at the Ritz Carlton Hotel. The Summit will be organized by MRC with the support of ICIS. The main idea of the Summit is to find a "the golden mean" between producers and converters. When producers receive exactly such margin of production, which helps them to invest in production expansion in order to substitute polymers imports, and the converters receive such price of feedstock that helps them to compete imported finished products. The Summit site gives an access to the live video of the Summit, speakers" presentations, as well as opportunities to ask questions or make appointments to any Summit partcipant.
