Technical Key Points
Ø In order to guarantee the required pressure of typical pump casting, when making the technical scheme in casting process, we must ensure the necessary riser pressure and effect of the casting，and control the technological yield of the casting between 50％－55％.
Ø For the two-channel pump body, we usually install several feeding heads in the appropriate parts of the upper side, and in the intersection of hot stream set a certain height of the side riser. If the flange size of the bottom is larger and thicker, to set side riser to feed the shrinkage alone is required.
Ø We are an innovation driven company, we have five patents, and will get another 13 patents within a few months.
