Technical key points

Ø Valve body is with simple structure, but require high pressure resistance, process demand is very strict; usually need to set pouring system in horizontal mould joints, in order to achieve sequential solidification and ensure effective complement from top to bottom .

Ø Open type internal runner can increase the effective cross-sectional area, ensure fast and smooth filling, reduce the temperature gradient, effectively slagging and improve riser feeding effect.

Ø Structural characteristics of the valve body castings make it easy to generate shrinkage and slag (sand) defects at the bottom, which seriously affect the pressure resistance of the castings, and may cause leakage of the media matter(water, gas, oil, etc.) during application.when setting feeding riser, feeding gate must be set or extended, if necessary, extend the feeding runner to the bottom of the casting.

TECHNOLOGY ADVANTAGES 

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.
