Production Process: Stainless Steel Casting

In stainless steel casting, a specific and general wax pattern of the preferred finished part is produced and mounted onto a wax tree. This first process involves the use of the metal delivery system. The wax tree is interchangeably plunged into a ceramic substance and topped with a stucco material. After this, it is left to dry out, and the process is repeated until a thick shell is achieved.

Once the shell is achieved, it is then melted out, creating a cavity in the form of the preferred pattern. The molten metal is then poured in such an area until it is filled. After the molten metal solidifies, the thick shell is fragmented, and the gating material is detached. The remaining parts are the finished product.

Stainless Steel Casting of Hawse PipeStainless steel investment casting is one of the first and most common types of marine hardwares, including hawse pipes. 316 cast stainless steel hawse pipe is extremely accurate and net shape. Since hawse pipes are created by using the same wax pattern, this accuracy can be maintained from casting to casting. Additionally, marine grade cast stainless steel can help to achieve maximum corrosion resistance and durability, which is suitable for marine enviroment.

Surface Finish: Mirror Polished
