We are a innovation-driven company, we have five patents and another 13 patents will be expected to get in short months. we are willing to develop all new material only if it's required in application.Advantage technology in composition control, especially super low carton steel, stainless steel and duplex stainless steel. 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.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.All our technology innovation only for one aim--- the best quality, even that means a higher cost and lower production rate.
We provide free technical service about casting parts and application issues.Free on-site touring and introduction of our factory We provide process design and validation for freeWe can guarantee on-time delivery of samples and goodsClose follow-up of all orders by special person and keep customers informed timelyAll after-sale request will be responded in 24 hours
