Sumitomo (SHI) Demag demos medical micromolding application at NPE2015


When machine builders want to highlight the precision and repeatability of a micromolding system, they often turn to medical applications. The medical device industry is famously demanding of its suppliers in terms of meeting specifications and quality expectations. To borrow a phrase, if you can make it there, you can make it anywhere. Sumitomo (SHI) Demag (Strongsville, OH) carries on that tradition at booth W623 at NPE2015, where it will mold a miniature POM gear used in a novel cataract surgery device.

The 0.524-gram gear, measuring 0.775 mm in diameter and with just 85 microns of space between the teeth, will be molded on a SE30DUZ direct-drive all-electric machine. Sansyu FineTool (Takahama City, Japan) built the single-cavity cold-runner mold, which will be loaned to Sumitomo (SHI) Demag by micromolder Makuta Technics (Shelbyville, IN). A robot from Yushin America Inc. (NPE Booth W763) will remove the micro-sized part.
