Abstract
An electroforming process and apparatus for forming an electroform with a roughened surface. An electroform with a roughened surface is formed by plating a reusable mandrel with a roughened surface. The reusable mandrel surface is roughened using a sandblasting device. The surface of the reusable mandrel is coated with a dual catalyzed non-self regulating crack free chromium deposit and a surface preparation to maintain the roughened surface. An alternate embodiment of the reusable mandrel utilizes a stainless steel mandrel without the chromium deposit on the surface. The roughened electroform surface enables toner distribution and sealing of the toner distribution module.
