Copper sleeve sand mould casting has stoma, how to return a responsibility?
(5) centrifugal casting. It is a method of casting a sleeve of special casting by changing the filling, casting and solidification conditions of a liquid alloy and by using the centrifugal force. (6) ceramic mold casting. It is by changing the mould material, high-quality refractory material and a binder, with special grouting forming method, obtain the precise size, smooth surface of the cavity, so as to obtain the thickness of the precision casting casting method. (7) low pressure casting. It is a casting process between a gravity casting (the process of pouring liquid metal into the mold under the action of gravity of the earth) and a pressure casting. By changing the filling and solidification condition, the liquid alloy in low pressure conditions from the smooth mold filling, under low pressure by the up and down sequential solidification, so as to obtain high-quality castings with compact structure. (8) vacuum suction casting. It is a method of casting a liquid alloy by causing negative pressure in the mold (mold) to make the liquid alloy crystallize and solidify in vacuum. This method changes the filling and solidification conditions of liquid alloys, reduces the gettering and oxidation of liquid alloys, and is suitable for casting high quality castings such as rods, tubes, and sleeves. (9) continuous casting. It is an efficient production process for casting tubes and ingots by continuous casting, solidification and cooling through a rapid cooling mold. (10) extrusion and liquid pressing casting. It is a comprehensive processing method for casting and forging.
