Stainless steel investment casting using silica sol process

Silica sol stainless steel precision casting is a high-precision forming technology widely applied in manufacturing. It utilizes silica sol as the binder for the shell, paired with high-quality stainless steel materials, to produce components with exceptional dimensional accuracy, smooth surface finish, and excellent mechanical properties.

The process features strict control over each stage, from wax pattern making,
shell coating and drying, to dewaxing, pouring, and post-processing. Its unique
shell-making method ensures strong shell rigidity and low gas generation,
effectively avoiding casting defects like porosity and shrinkage, thus enhancing
product qualification rate.

Suitable for stainless steel grades such as 304, 316L, and 17-4PH, this
technology caters to complex structural parts that are hard to machine, reducing
subsequent machining workload and production costs. It is extensively used in
aerospace, automotive, medical devices, valves, and marine engineering fields,
meeting high-performance requirements of various industries.
