During the casting process, materials such as molten metal is liquefied and poured into a mold before it’s hardened. Once the material is hardened it is removed from the mold before it is treated.
There are different casting processes and they are all typically used to create a range of products. Each of the processes ensures manufacturers can produce castings to their desired standard. Some of the types of casting processes in manufacturing are listed below.
Die casting is perhaps one of the most well-known types of casting around. During the process, the materials are molded under high pressure.
Molten metal is injected and the pressure is maintained until the metal is solid. Once the metal is solid it is removed from the die and waste material is removed. This type of die casting is quite advantageous as you can typically cast a lot of different shapes and sizes easily.
Sand castings tend to rely on naturally-bonded sand. Casting such as this is typically made up of spherical grains. Sand casting is typically used to reduce flaws, cracking, and tearing. The main advantages of this type of casting is that it’s inexpensive and large components can be made.
Vacuum Die Casting
Vacuum die casting is quite an advanced process that can work to improve the quality of parts that have been die casted. This is because it reduces or even removes dissolved gases and pores. One of the advantages of this type of casting is that it can cast much thinner castings than other methods. In addition to this, the mechanical properties can be improved as well as the quality of the die’s surface.
Lost Foam Casting
Another type of casting is lost foam casting. This is a method that uses foam or paraffin models. It offers casts that are similar in shape and size to other castings. With the ability to vibrate once it is buried in the sand, the cast contains metal that is formed once it has cooled and solidified.
This type of casting is typically used to create cylindrical parts such as pipes. This type of casting uses g-force to make the cast. Molten metal once in the mold is sent against the mold’s interior surface. The benefit of this type of casting is that it is unlikely to create and voids. If asymmetric parts need to be made they will not be able to be spun in the same way. Instead, pressure casting will be used.
There are many different types of casting processes that are used in manufacturing. As you can see, many of them are quite different. However, they all produce a great result depending on what type of product you wish to manufacture. It’s important that you use the correct casting process for your products to ensure they have the finish and shape that you need.
Using the right casting process ensures that you manufacture a high-quality product that is made to last.
