Full-Service Stainless Steel Casting Company

CFS Stainless Steel Foundry, started its casting business in 1998, has become one of the largest stainless steel investment casting manufacturers in China. With more than 20 years’ efforts, we have become a comprehensive stainless steel casting company that provided full services for our customers.

Redesign Service: When receiving the drawing from our customer for quoting, our engineer will first evaluate if the structure of the part suits our stainless steel investment casting process. The part may have to be redesigned especially when the wall thickness is too thin. After getting agreement with our customer, can we move on production.

In house molding: Mold making is the basic to start the manufacturing of stainless steel castings. CFS has in house molding capability to produce molds for cast stainless steel parts ourselves. We choose superior aviation aluminum as the material of mold, and machining the cavity of mold with high precision CNC machines. All these make the serving life of stainless steel casting molds longer. What’s more, the size accuracy and surface finish of final stainless steel casting will be better.

Currently, the wax injection and shell building processes are already automatic. In the near future, we will still try to import some new equipments to improve our stainless steel investment casting process. This effort will effectively make the quality of stainless steel castings more stable, and offer shorter lead time for our customers.

Heat Treatment: Normally, the heat treatment is suggested when the parts will be machined after stainless steel casting. The common heat treatment method adopted for stainless steel casting is solution treatment, which can eliminate the inner stress caused by stainless steel casting and reduce the hardness slightly, which can ease the further machining operation. CFS Foundry can supply heat treatment service when needed.

Secondary Machining: Although the investment casting process can creat stainless steel castings with good surface finish and close tolerance, it does not mean the castings finished are net shape always. Post machining has to be operated when the holes are not be cast out, and when there is a higher surface finish requirement. In our company, we are equipment with different machining equiments to fulfill various machining demands.
And with low labor cost, our machining cost is always more competitive.

Surface Finishing: CFS offers a variety of surface treatments, including shot/sand blasting, electropolishing, mirror polishing, vacuum titanium coating, etc.
