What is the maximum size of a part that can be produced by vacuum casting?

The maximum size of a part that can be produced by vacuum casting depends on several factors, including the size of the vacuum chamber, the available equipment, and the type and properties of the casting material. Typically, vacuum casting is more suited for small to medium-sized parts, such as those measuring up to 600mm x 600mm x 600mm and weighing up to 10kg. If a larger part is required, multiple sections or components can be vacuum cast and assembled later. It's important to note that the larger the part, the more complex the casting process becomes, typically increasing the lead time, cost and difficulty of production. In such cases, other manufacturing processes such as injection molding, rotational molding, or blow molding may be more appropriate.
