Vinyl records are made from polyvinyl chloride or PVC. The production process involves several steps that result in the final product we know and love. It all starts with a vinyl master, which is a lacquer-coated aluminum disc with the audio recording engraved into it. This master is created using a lathe, where the audio signal is cut into the lacquer with a tiny needle.
Once the master is created, it undergoes a series of electroplating steps to produce a metal stamper. This stamper is essentially a replica of the original master and is used to press the vinyl records. It is important to note that each vinyl record is pressed individually, making it a labor-intensive process compared to mass production methods used for CDs or digital formats.
The vinyl pressing process begins by heating a vinyl puck, also known as a biscuit or cake, in a hydraulic press. Once the vinyl reaches the right temperature, the stamper is inserted into the press, and the vinyl is molded between the two stampers. The stampers apply extreme pressure to the vinyl, shaping it into the grooves that contain the audio information.
Next comes the crucial step of applying the labels to the vinyl record. The labels are usually printed on paper or a thin plastic material, which is adhered to the center of the record. These labels contain important information such as the artist name, album title, and tracklist. They also contribute to the overall aesthetic appeal of the vinyl record.
After the labels are applied, the vinyl records are trimmed to their final size using a hydraulic cutter. This ensures that each record has the perfect dimensions for playback on turntables. The excess vinyl is removed, resulting in the familiar circular shape with a center hole.
Finally, the vinyl records go through a quality control process to ensure they meet the highest standards. This involves inspecting the surface for any defects, such as scratches or warps, and testing the sound quality. Once approved, the records are ready to be packaged and distributed to music stores or directly to consumers.
The unique process of creating vinyl records contributes to their charm and appeal. The physicality of holding a vinyl record, carefully placing it on a turntable, and gently lowering the needle adds a level of intimacy to the listening experience. The analog nature of vinyl also enhances the sound quality, producing a warm and rich audio that many music enthusiasts appreciate.
In conclusion, the expression written in vinyl involves a meticulous process of creating a vinyl master, electroplating to create stampers, pressing the vinyl, applying labels, and trimming to size. This art form combines craftsmanship, attention to detail, and a love for music. Vinyl records continue to captivate listeners with their unique sound and tangible appeal, proving that the expression written in vinyl will always hold a special place in the hearts of music lovers worldwide.
