Omnidex has been providing Shell Casting services to a long list of business customers for many years. We work with the industry’s best to bring you a wide range of metal casting services. If you are looking for an efficient sand mold casting method with high consistency, our Shell Mold Casting process can definitely meet your needs.
Invented in Germany during World War Two, shell casting (sometimes called shell molding) is a process similar to sand casting. It also uses temporary molds that are not reusable, but the molds are made with fine-grained, high-purity sand that is mixed with a thermosetting resin. The process offers superior dimensional accuracy across a wide range of ferrous and non-ferrous alloys.
The process of Shell Molding:
Shell casting is suitable for most ferrous and non-ferrous metals. Common materials include:
Since the shell molds are made with metal patterns and special sand compounds, the shell casting process can offer excellent dimensional accuracy and tolerances. Typical tolerances for this process are around 0.005 in/in (0.127mm/mm).
Shell casting can be used to make complex parts with fine details and very thin sections. It also offers excellent surface finish and tight tolerances. But this is not the full extent of its capabilities.
What makes shell casting stand out from most other processes is that it can be fully mechanized and automated, and it has lower skill requirements for workers. That means this process can have reach a higher production rate and can be easily scaled for mass production. These advantages make shell casting the ideal solution for large-scale production of small to medium-sized high-precision parts. This process is often used in the manufacture of camshafts, crankshafts, gear housings and many more.
