Types of casting
- [Instructor] With all of the considerations we've talked about in mind so far, it's time for a look at the practical applications. In prototype molding, there are also different kinds of casting. I'll discuss solid casting, combination casting, also known as overmolding, hollow rotational casting, and expanding casting. The first type of casting we'll talk about is the most common type, a solid casting. In solid, or standard, casting, the entire cavity of your mold is filled with one material, resulting in a solid cast component. I recommend solid casting for small to medium parts. If you decide to cast a larger solid, the weight could become an issue and the cost increases. The more material you use, the more expensive it is, so many designs minimize unnecessary bulk. Large, volumetric plastic parts made with factory methods found around you are generally hollow with structural design features and consistent wall thickness. These parts would still be considered a solid casting…
