Probably, if you are reading this discussion about sand casting processes, you are trying to determine which method of prototype casting would be most effective for your product. The best time to use a sand casting foundry for prototype casting is when:
Sand cast designs offer great flexibility in size and weight, making them ideal for prototypes. Materials and foundry size are the only limitations on size and weight.
While sand casting is flexible in both size and weight, it is also flexible in that prototypes of different complexity can be created through it. A great number of complex shape components cannot be cast using any other casting process.
A variety of materials can be used in sand casting, which is another benefit. Sand casting can be used with alloys that can be melted to create products.
Other metal manufacturing processes tend to be much more expensive when it comes to tools and equipment. Among the cheapest methods of casting, sand casting is the most common.
As one of the fastest casting methods, sand casting is able to produce components in a short period of time.
In spite of its many benefits, sand casting is not suitable for all forms of casting, as it is not only flexible but also cost-effective. For very niche products, sand casting is a good option. If you are planning to manufacture a product, sand casting might not be your best choice because:
Due to its high porosity, sand casting does not have the same strength as machined parts. As a result, sand casting is best suited for prototypes that are smaller and do not bear weight.
The dimensional accuracy will vary along the surface due to the shrinkage of metals during cooling, with some areas of the cast requiring greater accuracy than others.
If you want to create a prototype with a machined appearance, sand casting is not the best casting process to use. Metal hardened in the presence of sand will have the texture of the sand.
There are simply no ways to avoid defects in sand casting. In the process of sand casting, there are many possibilities for defects such as shrinkage, porosity, metal flaws, and surface imperfections.
Finished Products - Sand casting produces products that require post-production finishing due to the poor surface finish.
