Technical key points:
Ø hot sections of valve plate casting during pouring are very concentrated, do not place the risers dispersedly, big risers must be placed at the top of two-axis holes for feeding, and exhaust risers be placed far away from the main risers.
Ø Put cold iron blocks at the hot sections at the bottom of valve plate, it can help the risers solidify in sequence to enhance the risers’ feeling effect, at the same time, increase production rate and reduce casting cost.
Ø In the premise of ensuring a large cross-sectional area, a reduced and steady flow rate, no spray of molten steel which may caused secondary oxidation, the runner should be as thin as possible to reduce the suction area of the runner. The thickness of the inner runner should be less than 0.7 times of the wall thickness of the casting, and the width of the runner should be more then 4 times of the thickness, which is more favorable for the slagging and cleaning of the molten steel.
Ø We are a innovation-driven company, we have five patents and another 13 patents will be expected to get in short months.
Ø we are willing to develop all new material only if it’s required in application.
Ø Advantage technology in composition control, especially super low carton steel, stainless steel and duplex stainless steel.
Ø We cast very good surface of thin-wall castings, which is normally not easy to control for sand castings, but we made suitable technology and are able to guarantee smooth no-defect surface.
Ø Crack is fatal flaw for pressure resistant container. We can make sure no crack inside and outside of the pump and valve castings, and a good pressure-resistant performance.
Ø All our technology innovation only for one aim--- the best quality, even that means a higher cost and lower production rate.
Ø We provide free technical service about casting parts and application issues.
Ø Free on-site touring and introduction of our factory
Ø We provide process design and validation for free
Ø We can guarantee on-time delivery of samples and goods
Ø Close follow-up of all orders by special person and keep customers informed timely
Ø All after-sale request will be responded in 24 hours
