Manufacturers of silicon nitride riser tubes

Low pressure casting riser tubes is one of the key components of the low-pressure casting machine. Casting process, molten aluminum (temperature 700 ~ 900 ℃) every 3 to 5 minutes to be pressed to the mold cavity from the inner riser tubes. In the traditional production process of steel riser tubes, due to poor thermal shock resistance, corrosion resistance is poor, life is short, frequent replacement frequency, can not meet the continuous, high-quality production. Aluminum titanate all its low thermal expansion, good thermal shock resistance, and other characteristics of non-stick aluminum an ideal material for the preparation of liters of liquid tube. Our company can according to customer requirements of different types of riser tubes.
