Abstract
The process calls for testing and monitoring the pressure levels in different parts of the die casting apparatus during a casting operation, including the die cavity itself and in positive and vacuum pressure lines. The process also includes process steps which cools a vacuum valve adjacent the die cavity and cleans the valve and lines during a casting operation. The process calls for aborting a casting operation at various time during the operation if certain measured parameters are not acceptable.
