Stainless steel casting is one of the main steel casting types usually produced. In China, silica sol casting is the most precision casting process to produce stainless steel castings. Our silica sol casting method can achieve a general casting tolerance ISO8062(GB/T6414) CT5-CT6. One of the benefits of the casting process is the ability to create complex shapes and internal passageways within the mold that are not possible with machining. But in many cases, casting is not enough for some special shapes and dimensions. And post machining is preformed.
Main factors that determine whether the stainless steel castings will be machined, include casting process, complexity, and dimensional and surface finish requirements.
Once the precision of stainless steel casting can not fulfill the required finished component, machining operations will be choosed. If the tolerances for dimension and size are too tight for the casting process, the feature or hole must be machined.
Machining can not only help to achieve more precise dimensions, but also the surface finish will be much better. Nicer surface finish is important in applications when the part is meant to create a seal with another component or assembly.
Extra cost of machining is added after stainless steel casting. Before machining, our engineers will design and produce multiple fixtures and jigs to machine different planes of a part. Additional time also is needed to complete the whole machining process.
