AB Svensk Grammofonindustri

Swedish shellac, vinyl and cassette manufacturer. Also referred to as SGI or "Skivfabriken i Bro". Formally established in 1937 in Malmö, Sweden by Tage Andersson, where he was already pressing shellacs. In 1938, Emil Pettersson and his son Harry Svalfors joined the company management , both with a background in Ramonafabriken in Stockholm. Pettersson became CEO and SGI bought the "Gamla Mejeriet" (The Old Dairy) at the Upplands-Bro railway station, northwest of Stockholm. 1939 the production was moved there from Malmö. Several of the employees came along, but not Andersson himself. In Januari 1942, Andersson sold his share to his two companions but continued to be involved.. The Second World War proved to have lock-in effects on the record market. SGI expanded rapidly and soon it was among the largest manufacturers in Sweden, including brands such as Sonora, Husbondens Röst and Columbia. They produced their own raw material, shellac mass, and made their own matrices. From the beginning, they also had a printing shop and made their own labels. By 1947 the factory had 25 - 30 employees and produced 10,000 shellac records per day. Andersson now moved up to Stockholm and opened an office on Vasagatan together with accountant Svalfors. Pettersson and Svalfors left the company 1953. In the 1950s, SGI gradually phased over to vinyl production and would eventually manufacture cassettes as well. In the mid-70s, Nynäs Petroleum acquired parts of SGI and by new year 1979/80, the Andersson family sold their shares in the company, leaving Nynäs Petroleum as the sole owner. While Nynäs Petroleum would own AB Svensk Grammofonindustri until its liquidation in 1997, the actual factory was sold back to the Andersson family in 1983 who founded Audiodisc AB, run by Tage Andersson's son Torbjörn. Audiodisc moved its production to Bålsta in 2006 and the old SGI factory was demolished.
