Low pressure casting molds usually involve metal, and molten material enters the mold or mold to form the final form. During the molding process, the material is poured into a form usually made of metal. In low pressure casting molds, liquid metal is poured into a mold made of silicon Models made of rubber or similar materials. There are 2 main types of die casting:
Hot Chamber Die Casting: This is the more common form of die casting. In this case, the material is heated inside the casting chamber, hence the name "Hot Chamber". It is the preferred method since it does not require melting the metal elsewhere.
Cold Chamber Die Casting: Cold chamber die casting involves first liquefying the metal and then placing it in a cold chamber to funnel it into a mold. This is a process usually done for metals with a high melting point.
Advantages of low pressure casting molds:
1. This process produces a durable, high-quality product
2. Casting allows for greater design complexity
3. It is perfect for doing many intricately different designs at the same time.
Casting is a better choice if the intention is to make many complex parts where accuracy is critical. Usually, it is suitable for making many different parts, but it is not ideal when hundreds or thousands of identical elements are required .However, the finish of the casting has a higher quality look and feel, which is ideal for small, precise components.
