Technical Key Points

Ø  For the two-channel pump body, we usually install several feeding heads in the appropriate parts of the upper side, and in the intersection of hot stream set a certain height of the side riser. If the flange size of the bottom is larger and thicker, to set side riser to feed the shrinkage alone is required.

Ø  For small and medium-sized pump body castings, we usually set pouring system in the horizontal parting surface, with semi-circular horizontal runners and scattered inner runners, so as to reduce hot section and expands the filling surface, in the premise of ensuring the cross-sectional area, try to increase the width thickness rate (7: 1-5: 1). For larger pump castings, surface area is large and flow route of molten steel is long, so the temperature of steel drop fast, normally we use the bottom injected open-type pouring system, to achieve effective, fast and smooth filling.

Quality Assurance

Ø Strict contract auditing invloved all departments to assure the feasibility of each order.

Ø Process design and validation before bulk production.

Ø Strictly control on all raw and auxiliary materials, All raw materials reach the world advanced level.

Ø On-site inspection to all processes, inspection record keep traceable for 3 years.

Ø 100% inspection of finished sprouts before shipment.

Ø Advanced and complete testing and inspection equipment: NDT, metal Microscope, impact tester, hardness tester.

Ø Regular training for inspection staff.

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 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 All our technology innovation only for one aim--- the best quality, even that means a higher cost and lower production rate.
