About Stainless Steel Casting Parts
Sango Automaton is a foundry factory that can provide one-stop services for casting blank manufacturing and precision casting processing, and can provide customers with customized stainless steel casting parts, casting iron parts and other products.
Since its establishment in 2010, Sango has been providing equipment parts casting services for equipment manufacturers in the field of food packaging machinery, and we have rich experience in the production of stainless steel casting parts, and the materials commonly used are CF-8M (stainless steel 316), CF-3 (stainless steel 304L), etc.
Product Properties
Excellent corrosion resistance
Stainless steel materials contain chromium (Cr), which can form a dense oxide film on the surface of the casting, which is chemically stable and self-healing, and can isolate the contact between the matrix and corrosive materials, so stainless steel casting parts have good corrosion resistance.
Good mechanical properties
Stainless Steel Casting Parts have high strength, high hardness, good fatigue resistance, and higher tensile strength, yield strength, and toughness than gray iron, which makes them widely used under high loads and certain impact stresses.
Good ease of cleaning
The surface of the stainless steel casting part is smooth and dense, resistant to bacteria and dirt, and easy to clean and sterilize. This inherent easy-to-clean property allows it to be widely used in food processing, pharmaceutical, medical, and other fields.
Material Grades
The material grades we generally use in the production of stainless steel casting parts include CF-8M, CF-3, CF-3M, etc. Below I will briefly compare the direct differences between these three types of materials.

Production Process of Casting Stainless Steel
Pattern Making
According to the drawings provided by the customer, a pattern similar to the shape of the final part is prepared, which needs to reserve a certain machining allowance, shrinkage allowance and draft angle to ensure that after subsequent processing, the casting can meet the specifications of the final part.
Core Making (optional)
This step is only available for stainless steel casting parts with inner cavities, using a special core sand to make a sand core that forms the inner cavity of the casting, and spraying a refractory coating on the surface of the sand core.
Molding
The process of molding is generally divided into two parts. The first is to prepare the upper and lower two molds, put the COPE part of the pattern into the lower sand box, fill the sand ramming to prepare the drag, and then put the drag part of the pattern into the upper sand box for ramming and make the gating system and riser to prepare the COPE. Then take out the pattern and spray the mold coating on the upper and lower mold surfaces, put the sand core into the drag if you need a sand core, then merge the cope and drag, align the dowel pin and lock it. Form a cavity in the mold that is the same shape as the part.
Pouring
Once the molding is complete, molten metal can be slowly injected into the gating system. After the injection is complete, wait for cooling and solidification.
Shakeout and Cleaning
After the metal solidifies, it enters the process of shakeout, which separates the casting from the mold by vibration. Subsequently, cleaning is carried out by vibration, shot blasting, cutting, etc., to remove the molding sand and core sand adhering to the casting surface.
Heat Treatment
The casting is then heat treated to eliminate residual stress and restore the stainless steel casting parts to their optimal corrosion resistance and toughness.
Pickling and Passivation
After the heat treatment is completed, it is necessary to use a mixture of nitric acid and hydrofluoric acid for pickling, and then use nitric acid for passivation to remove the scale formed on the casting surface during the heat treatment process, and re-form a dense passive film on the surface.
Precision Machining
After completing all the above processes, the final step is precision machining, machining the casting surface with precision machining requirements to achieve the dimension and tolerance required by the drawing.
This concludes the entire production process for stainless steel casting parts.
