How to Reissue a Record page 5  The stampers are trimmed and fitted onto the record press: 
Rick, the plant foreman at RTI, inspecting the inside of a record press. A stamper for Side One is placed in the top chamber of the press, while the Side Two stamper is attached directly below. A donut of molten vinyl, sandwiched between the two labels which will identify the record, are set in position by an automated mechanism. In a one-step process, the stampers press the materials together to create a two-sided LP, complete with record labels. The hot vinyl is spread across the stampers, filling in the engraved valleys to form record grooves. The press remains clamped for about a minute before it is pulled apart, revealing the new disk. Excess vinyl on the outer perimeter is trimmed away and it is placed on a spindle with other new records to slowly cool. At the same time, a new vinyl is placed between the stampers to press the next LP. After cooling, the records are inspected and packaged for shipment. Periodically, a newly pressed disk is removed from the spindle and taken to quality control. Inspectors will listen for any imperfections caused by the press. When a problem is detected, the machines are stopped and adjusted before stamping is resumed. Sounds easy, huh? © Copyright 2012 Classic Records. Information contained on these
