Advantage of Heater Protection Tube for Aluminum Die Casting 

1.With good thermal shock resistance and high temperature mechanical strength,therefore, the products can withstand severe thermal load of high temperature heaters. Repeated insertion and withdrawal of the products in the course of operation will not affect the performance. 

2.Low wettability against molten aluminum can reduce the contacting of slag on the protection tube, and provides easy maintenance and operation. 

3.Excellent insulation can assure no contact (insulation) between heater and molten aluminum or other molten metal.
