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.

Oblique Cut Lamination
Contact UsShearing is a common cutting method for silicon steel sheets. Silicon steel is sheared with a carbide blade, which can cut the required size and shape. Shear method on the thermal impact of silicon steel core is small, the kerf is smoother, but the shear force is more damage, easy to produce deformation and burr. Therefore, the shear method is suitable for cutting smaller lamination, the requirement of surface flatness is not too high occasions.
Our company has introduced advanced oblique cut equipment, which is able to cut large silicon steel core to meet more needs of customers. -
