The Vinyl Record processThe Cutting Process![]() Master lacquer in the process of being cut on our Neumann Lathe. ![]() Carl inspecting test cut prior to cutting the master lacquer. ![]() This view through a macro zoom lens shows grooves being inscribed into the lacquer disc via the cutter head. Note the lacquer thread being drawn into a tube on the right. Carl performs critical groove depth and width calculations on all projects, before proceeding with the actual cut. The Plating Process![]() The lacquer is cleaned with a solution of soap and water ![]() The Lacquer is then spray coated with a solution of tin chloride and liquid silver. ![]() Next the Lacquer is submerged into a nickel sulfate bath and electro chargers fuse the nickel solution onto the silver coated disc. This process takes approximately 1.5 hours. ![]() The master lacquer with “father “or stamper attached is removed from the nickel solution. ![]() The metal “father” or stamper, depending on the process ordered, is separated from the lacquer master. ![]() Precision punching of the center hole is critical to centering the stamper on the press. ![]() The stamper is trimmed to a diameter of 12 ½”. The Pressing Process![]() Poly vinyl pellets are poured into a hopper. ![]() The vinyl pellets are heated in a extruder and formed into a “biscuit”. ![]() The vinyl “biscuit” is placed between both nickel stampers, one above for the A side and one below for the B side. Paper record labels are positioned on the top and bottom of the biscuit. With 380 degrees of heat and 100 tons of pressure, the biscuit is molded into a record. The pressing cycle takes 28 – 30 seconds per record. ![]() Molded record “hot” off the press…..notice excess flash around the outside edge. ![]() Trimming the flash off the edge of the record ![]() Finished records are stacked and allowed to cool thoroughly before being packaged. |
