CD and DVD manufacturing is actually just the process of electroforming.Electroforming is the step in the CD/DVD manufacturing process that takes place after glass mastering has been completed. Glass mastering is the step by which information is encoded onto discs using laser beam recorders. Electroforming, then, is the process by which the sensitive disc that has been produced from glass mastering is taken and made to be tougher. While this may sound simplistic, it is exactly what the process of electroforming is all about. The glass master disc can be damaged extremely easily and it is the process of electroformation that will allow the disc to become hard and strong, able to undergo the rough handling it may receive by CD and DVD purchasers in the future.
Electroforming utilizes injection-molding equipment in order to strengthen the optical discs. The procedure begins with the disc being clamped into a conductive plating frame that put slowly onto a plating tank. The plating tank c ...more
