Introduction of different casting processing methods
Introduction of various casting processing methods, each method has its own unique advantages, Great Wall Casting Steel takes you to know about these methods:
1. Continuous casting: The mold is a water-cooled mold. After the liquid metal is continuously injected, the solidified product will be continuously pulled from the other direction of the mold. The production efficiency of this method is still relatively high, but the equipment cost will be relatively high, which is suitable for large-scale production.
2. Vacuum suction casting: The vacuum of the crystallizer can also cause negative pressure and suck the molten liquid metal to form. The product has no defects such as pores and trachoma, and has high production efficiency. It is suitable for large-scale production of copper alloy, aluminum alloy and other castings, and the equipment is relatively simple.
3. Squeeze casting: A certain amount of liquid metal is poured into the lower part of the mold, and then the mold is quickly closed and then pressure solidified. The product organization produced by this method is more dense, without air holes, the equipment will be more complicated. The life of the die for extruding steel alloy is relatively short, and the shape of the product processed in large quantities is relatively simple, but the material cannot be iron alloy, internal quality requirements or thin-walled castings with large contour dimensions.
4. Graphite mold casting: The graphite material is used for molding and then gravity casting. This way, the product produced by this method is compact, the size is more accurate, and the production efficiency is also higher. It will be easily broken, and the labor time is relatively poor when manual operation. It is more suitable for producing small and medium-sized parts such as copper alloy propellers that are not particularly complicated, and can also be used for titanium alloy castings.
