An overview of <br />metal finishing operations is provided below to provide some background information on the <br />generation of this hazardous waste and on the supporting processes and operation that are <br />associated with this waste. <br />The Metal Finishing Operations Group WO) <br />in the SLAC Mechanical Fabrication <br />Department (MFD) performs plating of carbon steel, stainless steel, copper, and aluminum <br />parts and uses several processes for cleaning and plating of metal parts. The process <br />operations are rarely mass production -oriented. Instead, WO operates on a job -shop or <br />small -batch basis. Parts are subjected to several process steps, depending on the substrate <br />E metal and the plating that is added to the substrate surface.
