Technical Key Points
Ø Pouring speed: in the case of ensuring smooth gas discharge from the cavity, higher pouring speed can be used;pouring operation requirements: after casting, as soon as the castings solidified, remove the pressure iron and box, to reduce the casting shrinkage resistance and avoid cracks and flaws.
Ø For the pressure resistant castings of valve body, to prevent shrinkage and slag defects are the key points that always need to pay great attention when design casting process, all aspects need to be considered to reach a comprehensive balance, among all the measures, to increase the riser height is a very effective one.
Ø Strict contract auditing involved all departments to assure the feasibility of each order.
Ø On-site inspection to all processes, inspection record keep traceable for 3 years.
Ø Process design and verification before batch production.
Ø Strict control of all raw and auxiliary materials, so that all raw materials to reach the world's advanced level.
Ø We will train inspectors regularly.
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 will develop new materials when necessary.
Ø Our advantage lies in component control, especially for ultra low carbon steels, stainless steels and duplex stainless steels.
Ø All our technology innovation only for one aim--- the best quality, even that means a higher cost and lower production rate.
