There’s a lot more to it, as @carbonman says you’ll need a chemical bath to coat the acetate, which is then used to make the stamper (“mothers” and “fathers” in the parlance). You will also need a huge boiler to stamp vinyl-- records are made by placing a small ‘puck’ or ‘donut’ of vinyl onto the stampers, then using heat to melt them down. This video shows how it’s done manually, though most plants have larger automated machines (this also illustrates how unique color vinyl discs are done.)
