Stainless Steel Valves for Investment Casting
Facing coat and shell formulation for investment casting of stainless steel valves, focusing on shell strength and casting surface quality.
Scenario Description
Refractory materials for shell face and back layers
In investment casting, the shell face coat material significantly affects surface roughness and dimensional accuracy of castings. Mullite powder is suitable for face coat slurries and stucco applications, while sand materials are used in backup layers to enhance high-temperature shell strength.
- The top layer uses fine powder with a concentrated particle size distribution.
- Full-specification supply of sandblasting and backing sand materials
- Available in customer-specific formulation ratios
