We work in close partnership with our customers to understand their needs and develop high-quality answers that enhance industrial glass production.
We have been a leader since our inception, and our unwavering commitment to investment in research and development has granted us over 100 patents.
We are the only furnace company in the world to have a wholly-owned research and development department, which is crucial to all technological advancements.
More than 50 years ago, SORG changed from a furnace factory to a technology venture. In 1971 the first full-electric furnace type VSM® was developed and started operating. Since then, SORG has been improving or developing technologies. We engineer new furnaces, components and techniques —everything to offer our customers solutions for their individual needs and to bring the glass industry forward. Our 100+ patents prove it.
