Electric heating for pressure die casting nozzles
Abstract
The possibility of using electric heating of magnesium pressure die casting nozzles was investigated. Temperature calculations were carried out which indicated its feasibility. A test rig was built and temperature gradients in a full size nozzle were measured. The results suggest that resistance heating of the nozzle is possible. A life test of the resistance heater gave a satisfactory result.
