Definition of Record press
A record press or stamper is a machine for manufacturing vinyl records. It is essentially a hydraulic press fitted with thin nickel stampers, which are negative impressions of a master disc. Labels and a pre-heated vinyl patty (or biscuit) are placed in a heated mold cavity. Two stampers are used, one for each side of the disc. The record press closes under about 150 tons of pressure. The process of compression molding forces the hot vinyl to fill the grooves in the stampers, and take the form of the finished record.
