PROJECT DESCRIPTION:
Staneco Corporation designed controls for a machine that produced alloys in small batches. There were 20 recipes for different alloys. The cycle started by purging the chamber of air followed by gases being introduced into the chamber. The metal was heated to the required temperature by an induction heater. When at temperature, the crucible was then tilted in steps at different speeds using a servo motor to pour the metal into a mold. The crucible was then returned to the home position and atmospheric pressure was re-introduced. Temperatures were recorded on an electronic chart recorder.

PROJECT OUTCOME:
The new control system provided increased reliability along with a more efficient operator interface.
