Problems solved by technology

In the multi-position parallel pressurized casting process, compressed air is used in the holding furnace to reduce the temperature of the aluminum melt in the riser, and the aluminum melt can last up to 40~50min, especially after casting, the mold takes longer to remove, the aluminum melt is likely to solidify first at the water inlet of the riser and the mold, the casting cannot be effectively fed, and the riser cannot be pulled out This phenomenon seriously affects the casting production efficiency and the quality of castings
