In the production process of the glass containers, burnt-on carbon will accumulate on the mould surfaces. Toyo Glass has so far used sand blasting for cleaning the glass moulds. “We needed another method because sand blasting is destructive to the mould surface. We believe that ultrasonic cleaning will bring us considerable savings in the production costs because the lifetime of the moulds will likely be doubled. The new method meets also our cleanliness requirements well”, says General ManagerMr. Hiroyuki Nakamura.

TOYO GLASS Co., Ltd. is a leading manufacturer of glass containers in Japan. The company has been producing quality glass for more than 120 years since 1888. The extensive know-how, technology and engineering in the glass manufacturing from raw materials to finished products are their valuable assets.
