Miyoshi Manufacturing Co., Ltd. has adopted hot melt molding with the aim of miniaturizing and lightweighting digital terrestrial antennas. This initiative was featured in an article by the Hokkaido Bureau of Economy, Trade and Industry, so we would like to introduce it.

By low-pressure injection molding of adhesives, complete waterproofing is achieved. - One-component instant curing (a cycle takes several tens of seconds). Cost reduction is realized as an alternative to potting. - Since it is molded in a mold, shape optimization can be achieved according to the parts. Miniaturization and weight reduction are realized. In water-related equipment (refrigerators, washing machines, showers, water purifiers, disposers, etc.), hot melt molding is adopted for waterproofing purposes. We will introduce examples of applications for these purposes. Please consider this when looking into waterproofing.
