Our products are mainly used in the smelting process of the aluminum casting industry and the extrusion process of aluminum profiles. China High Purity Magnesium Ingot and Magnesium Ingot Factory Supply, Billet In Extrusion, Melting Furnace For Aluminium, Refractory Cast Material,Double Angle Aluminum Extrusion. Refractory materials needed: heat storage balls, castables, refractory bricks, aluminum silicate cotton plates, plug heads, launder structures, ceramic foam filter plates, filter boxes, manifold plates, conduits, adapter plates, graphite rings, crystallizers. The product will supply to all over the world, such as Europe, America, Australia,Romania, Amman,Rotterdam, Greenland.Under the action of pressure, the heated aluminum rod is divided into several metal flows, enters the welding chamber through the shunt hole, collects in the welding chamber, and is welded again in the environment of high temperature, high pressure and high vacuum, and finally flows out through the gap between the mold core and the die hole, so as to form a pipe or hollow aluminum profile that meets the size and performance requirements, as an aluminum door and window profile or industrial aluminum profile. If bending is required, a bending tool is added to the rear device.
