There are several types of machined castings and the less discussed methods are continuousand lost foam casting. Both have complicated technological processes and complex technical characteristics. Here are the facts on the two types of castings.
It is a state-of-the-art casting method that involves the continuous pour of molten metal into a crystallizer. Once it solidifies, the casting is continuously pulled out from another end so the metal can obtain any specific length.When it comes to technical characteristics, continuous casting can enhance production efficiency. Likewise, because of the simplified techniques, this process can dramatically reduce the desired production area and labor intensity. Another advantage why using continuous casting is recommendable is the fact that it offers good mechanical properties, uniform structure, and dense crystals.Continuous castings are often applied in productions with cross-sectional shapes like pipes, rod billets, slabs, and ingots. This type of casting is also used in components made of magnesium alloys, aluminum alloys, copper alloys, iron, and cast steel.
Otherwise known as a solid casting, lost foam casting is a contemporary method that involves a combination of foam or paraffin models akin to the shape and size of the casting to produce a model cluster. After drying and brushing the refractory coating, it is buried in dry sand and poured under intense pressure to vaporize the model.As for its technical characteristics, lost foam casting can reduce production costs and investment. It also offers a high degree of freedom during the production process, flexible design, and no parting surface.As for application purposes, it works best in producing different sizes of precision castings with complicated structures. The best thing about this type of casting is that there are no restrictions on the kind of alloy used.
Apart from lost foam and continuous casting, there are also other types of casting processes such as squeezing die casting, vacuum die casting, and many more. Contact our experts at Ferralloy Inc. to know more!
