Technical advantages 

1.Low energy consumption

We use submergible heating element and heat source is in the centre of aluminum solution. So we have great heat transferring performance which can save more energy consumption than traditional heating methods. 

2.Improve the quality of die- casting parts

Heat source in the centre of aluminum solution can fully ensure it heat evenly. Aluminum solution at the top of the kiln will not be oxidation because of overheated. As thus, the loss of aluminum will be lower, the quality of aluminum die-casting parts will be better, at the same time, the damage due to residue of aluminum dregs in the kiln wall will be reduced. 

3.Long life time

Excellent corrosion resistance, the best mechanical strength and excellent thermal shock resistance, these characteristics extend the lifespan.
