The process begins with the production of wax patterns, which are replicas of the final stainless steel product. These patterns are typically created using an injection molding process to ensure precision.
The wax patterns are then assembled onto a central runner system to create a tree-like structure, optimizing the casting process and allowing for multiple parts to be cast simultaneously.
The assembled wax patterns are coated with a ceramic shell. This is done by dipping the pattern into a liquid ceramic slurry and then sprinkling fine sand onto it. The shell is allowed to dry and harden, forming a strong mold.
The cast parts undergo various finishing processes, including sandblasting, machining, and polishing, to achieve the desired surface finish and dimensions.
