Normally, the passage inside the valve should be smooth, and considering the
corrosive medium, stainless steel should be used Valves made by silica-sol
casting process are preferred.
How to shape the wax sample is the key step in the production of valve body
castings. Due to the complex body The cavity or the lining size is too long to
mold the wax sample in one time. So we usually use two molds and then weld the
separate wax molds together. This method not only ensures that the valve body
is formed in one pass, but also reduces costs. The final step in production is
the pressure test. Each piece is inspected to ensure air tightness and leak
free delivery.
Silicone casting is a type of lost wax casting and is mainly used for products
with high corrosion resistance and high precision dimensions because of its
better surface quality and smaller dimensional geometry deviations. Main silica
sols
We produce cast steel parts including meat grinder parts, valve castings, pump
castings, marine hardware and furniture Usually, the tolerance of silica sol
cast parts is within GB/T6414, CT5~6, weight range from 20g to 50kg and surface
finish Ra6.3.
