Brass Valve Body Three-way Gravity Casting
In order to eliminate casting defects such as shrinkage, porosity, and coarse structure in the production of HPb59-1 brass valve body, it was determined through casting process experiments that a suitable shaped feeding riser was added at the hot joint of the valve body to strengthen the feeding of the casting and move the shrinkage hole out of the valve body

Brass valve body three-way water glass investment casting parts
In order to eliminate casting defects such as shrinkage, porosity, and coarse structure in the production of HPb59-1 brass valve body, it was determined through casting process experiments that a suitable shaped feeding riser was added at the hot joint of the valve body to strengthen the feeding of the casting and move the shrinkage hole out of the valve body; Using trace amounts of boron as a metamorphic additive to refine the valve body structure effectively eliminates the aforementioned casting defects
