From Factory To Hi-Fi
You adore your albums. I’d almost bet they’re meticulously organized, their plastic sleeves free from any wrinkles. Collectors don’t come much more earnest than those who have fallen in love with vinyl records. And have you ever thought about just how that perfect little piece of wax gets into your hands and on your turntable, whether your passion is rock vinyl, jazz vinyl or just about any genre under the sun? It’s a surprisingly simple process.
Logically, the method of making and pressing the albums of today has its origins in the steps first given by Thomas Edison’s photograph. But before anything resembling a vinyl record is produced, a medium is needed. In the studio, a master recording is made, where musicians, producers and audio engineers work hand in hand to perfect the recorded sound.
Once the master is acquired, a gloss is placed on a record-cutting machine. During its production, the gloss coating dries up to a perfectly silky exterior. As it rotates, electronic signals from the master recording are transmitted to a cutting head, which holds a stylus. An engineer moves the cutter and a microscope then examines the test groove and aDJustments are made to the cutter. A computer monitors the cutting and adjusts the spacing between the grooves as needed since the recording is one continuous groove. Although not a vinyl record yet, it’s beginning to take shape.
From there, the imprinted lacquer is sent to a pressing plant – perhaps a more industrial-looking environment than most vinyl album enthusiasts would like to admit. The lacquer is then washed with soap and water and sprayed with liquid tin chloride and liquid silver. Creating an inverse of the gloss, as opposed to grooves, the subsequent metal master has ridges. The metal master is then utlized to produce a metal record, also called as the mother. From the mother, a stamper is born. The stamper is placed on a machine, which punches a hole in the center and removes the edges to create a diameter of 12 inches. Stampers are negative versions of the original recording that will be utilized to make the actual vinyl records.
Finally, the stamper is placed in a hydraulic press. Black Polyvinyl choride pellets are put in an extruder, which turns them into small “biscuits”. The biscuit is then placed in the press which has two stampers mounted within – one for each side of the record. Steam softens the plastic while the stampers create impressions of the master recording onto soon-to-be-vinyl albums. Cool water is then employed to harden the disc. The final step? Finding its place in your vinyl record collection and on your turntable, whether its rock vinyl or jazz vinyl.
