How Is a Vinyl Record Made: The Process of Getting a Record Pressed?
Have you ever wondered how a vinyl record is made, which transports you to a place of musical bliss? How does the music we love so much get physically pressed into this beautiful physical medium? Vinyl records have a tactile quality that cannot be easily copied in the digital world, and for many, this definite aspect makes up the majority of the overall appeal. Unlike a CD, which is, of course, a remarkable piece of technology, can hardly be called charming, but a well-made vinyl pressing record is a beauty to appreciate. So, if you are here, you are at the right place to know how papers are manufactured. The Vinyl Manufacturing Process Step-1 – Manufacturing the Master Disc These flat discs are made from an aluminium core, first polished down to a smooth finish. Then the discs are placed on a conveyor belt, ready to be coated in nitro lacquer. Rollers catch the excess run-off lacquer, which is used again. Once the quality control is passed, a hole is punched into the centre to complete the new master disc. The new discs will be carefully packed using separation strips in batches between each one to protect the fine lacquer surface. Step-2 – Cutting the Master Disc The new shiny master discs are cut using a lathe recording machine, where it is placed. Then, a microscope and cutter are moved to the disc’s outer edge, ready to perform a test cut. After inspection, he will begin recording, allowing the lathe to cut a continuous groove representing source material using a sapphire tripped cutter. A vacuum removes the scrap lacquer, which is created by cutting. To prevent any imperfections, dust should be kept away from the lacquer’s surface. Step-3 – Creating the Stamper After the master record is cut, we must first create the stamper and go through a galvanic process. At first, a silver spray is to be applied to the lacquer. Silver that does not stick will wash away. A duller metal is added to the silver side, which hardens the disc, ready for electroplating. In this process, a silver-plated disc is dipped into a liquid tank that contains dissolved Nickel. Once it fills the grooves, the disc and the metal layer are removed from the electroplating tank and the original lacquer disc, respectively. The metal layer which is removed is the stamper. The manufacturer uses a visual centring punch to make a hole in the centre before moving to trim off any excess metal to complete the stamper. Step-4 – Preparing the Labels Labels must be created first, as they will combine with the record as part of the vinyl pressing process. Labels are produced in square stacks, which are punched first and cut into circles. A brand will typically get several test pressings created first (usually 5-10) when record pressing. Step-5 – Pressing the Records The manufacturer pours Polyvinyl Chloride pellets into a hopper for record pressing, which feeds the material into an extruder that condenses them into a small puck shape (biscuits). Both the biscuit and the labels are then pushed into the press, where high pressure and heat are applied to stamp the record. Once it is cooled, the excess vinyl is ready for a final trim. Finally, we have a new vinyl record ready for hours of listening enjoyment.
