u Take effective measures to reduce the casting temperature to eliminate crack defects, at the same time reducing the temperature drop of molten steel to ensure the filling capacity of steel. Main technical measures: one is to directly reduce the casting temperature, the original pouring temperature of 1600 ℃ -1610 ℃, and now strictly control the temperature at 1570℃ -1580 ℃. Second, to reduce the temperature drop of molten steel. After the mold are assembled, blow heat wind 150 ℃ -200 ℃ to the cavities for 60 min-90min, and stop blowing 5min before pouring.
u Pouring should be fast, first calculate the pouring time, apply plunger type leakage bag to pour in stipulated time, this process are with good slag stopping function, at the same time pouring pressure is increased. Pouring speed must be controlled to be full stream and flow into the cavity fast, till pouring gate be filled up.
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
