When it comes to casting aluminum products, there are basically four types of casting. The types of casting are sand casting, investment casting, die casting, and permanent mold casting. All of these methods have a purpose in the manufacturing process, but there is a time and a place for everything.
Sand castings can be tricky because they require you to recreate the mold each time you create a cast. They’re the most affordable option, but if you’re looking for a high-quality finish and a long-lasting mold, sand casting isn’t for you.
On the flip side, die casting is the most expensive type of casting. It can cost you thousands of dollars. This method is used for high-volume projects like creating kitchen cabinet knobs. This method should only be considered if you require a large amount of your product. Investment casting is interesting because you can use any type of alloy metal to complete the project.
Finally, permanent mold casting should be considered when creating any aluminum products. It’s only a little more expensive than sand casting, but you are able to reuse the mold. You’ll be happy with the good finish on the final product.
