Abstract
A control system and method for controlling a low-pressure die casting machine wherein the pressure within the dies more accurately tracks the desired recipe pressure. The control system senses pressure in the dies and compares the sensed pressure to desired pressure. Should the difference between the sensed pressure and the desired pressure be indicative of a problem in the casting operation, subsequent casting cycles are prevented. Should the difference between the sensed pressure and the desired pressure be indicative of a potential catastrophic failure, the current casting cycle is immediately terminated, thereby minimizing the possibility of catastrophic failure. The control system has commercially available and easily replaceable components and, thus, can be quickly repaired to reduce machine downtime should any component fail.
