Defunct Swedish pressing plant.
Records pressed here can commonly be identified by ‘GP’ or ‘Grammoplast’ etched in the runouts, often found alongside a date (yymmdd or dd/mm-yy). The official test pressings of the company can be identified by ‘Provskiva’ printed on the labels, meaning ‘test pressing’ in English.
Company history.
In the early 60's, company founder Svante Rääf (1927-2012) was invited by Sture Wahlberg and Olle Nyqvist to take over an existing record pressing plant (name unknown).
The label GPRecords and GP-Produktion started using a logo in the 60's which later Grammoplast also did. These businesses were most likely related.
In 1969, the name Grammoplast was used for the first time, while the pressing plant was located on Rörstrandsgatan 37. Sometime in 1976-77 it moved to Spånga. The building was originally a milling stone factory, later a carpentry. Ca 20 workers were employed at the time.
In 1986, they bought the vinyl pressing business part from Toolex Alpha. In 1989-90 Grammoplast was the largest vinyl pressing company in Sweden.
The company was bought from Svante Rääf by a group of former employees during the autumn of 1991. The company was renamed as DCM (3), Disc & Cassette Manufacturers, with shift towards CD production.
