How is a vinyl record made?
The production of a vinyl record involves a detailed and painstaking process. First, an audio master is created and recorded onto a sheet of acetate. This sheet is then used to make a metal matrix, which is placed into a vinyl press to form the record.
From Sound to Acetate Sheet
It all starts with music. Artists record their music and it is converted into an electrical signal that is recorded onto a sheet of acetate using a cutting needle. This needle then records the grooves of the music onto the sheet, creating what is known as an "acetate record."
Creation of the Matrix
This acetate disc is then used to create a metal matrix. The acetate sheet is sprayed with a silver solution and dipped into a nickel bath. This process is called electroplating and results in a metal matrix, a kind of negative of the original acetate disc.
Vinyl Pressing and Record Formation
This metal die is placed into a vinyl press, where a hot vinyl "biscuit" - a kind of soft vinyl cake - is fed into it. The press applies heat and pressure, and the vinyl is shaped according to the grooves in the metal die. After cooling, you have your vinyl record ready.
Labels and Packaging
Finally, a label is placed in the center of the record and it is packed in a sleeve. Many vinyl record collectors also enjoy vinyl record furniture that allows them to store and display their collection in an attractive manner.
