At the recent NPE show, Makuta Technics, Inc., of Columbus, IN, ran a two-cavity mold for a POM bobbin measuring just 1.11mm x 0.64mm x 0.94 mm, for an overall part size of just 0.668 mm3.

The mold for the part was made by Sansyu Precision of Takahama City, Japan and ran on Sumitomo’s new SE18S all-electric machine.

“In micromolding, even though you’re injecting a very small amount of resin, to fill out the part completely you need high pressures and speeds and precision control,” says Stuart Kaplan, president of Makuta Technics. The bobbin is used in miniature electrical devices.
