Technical Key Points
Ø In order to ensure the casting pressure of typical pumps, in the formulation of technical program, in the pouring process, must ensure the necessary riser pressure and influence, and control the yield between the technology - casting 50% 55%.
Ø For the double channel pump, usually installed multiple feeding head in the appropriate place in the upper part of the hot runner at the confluence of the side wall of a certain height setting. If the bottom flange size is large and thicker, the side riser needs to be set separately.
Ø Cold could put them in a hot section away from the riser, to prevent cracking, realize sequential solidification.
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 All inspectors have international certificates.
Ø Qualified WPS and professional welder ensure welding quality.
Ø Strict product testing will be carried out before shipment.
Ø We are an innovation driven company, we have five patents, and will get another 13 patents within a few months.
Ø Our advantage lies in component control, especially for ultra low carbon steels, stainless steels and duplex stainless steels.
Ø We cast very good surface of thin-wall castings, sand casting is usually not easy to control, but we adopted the appropriate process, can ensure smooth surface, no defects.
Ø All of our technological innovations are for one goal - the best quality.
1.Can you provide machined finished parts?
A: Yes, we have our own machining center, we have machines for different machining process and CNC machining center.
2.What is the delivery time of pattern, casting parts and machining finished parts?
A: In general, pattern making time is 20-40 days base on the design of the parts, sample making time is 20-30 days, machining finished parts lead time is 40-60 days. The lead time will vary base one different design and weight of the parts, please contact us for details.
3.How is your goods quality?
A: We cooperated with many world class companied for many years, for examples, Stertil B.V., LKL, FLOWSERVE, Ruhrpump, Hitachi, Swater, GE, CAT, WKM etc. our products received good response from our customers.
4.What kinds of physical and chemical testing you can provide?
A: The physical and chemical testing we provide include:
Ø chemical composition testing.
Ø physical property testing: ardness test, Tensile performance testing, room temperature impact testing, low temperature impact test.
Ø NDT: PT, MT, UT & RT.
Ø Metallographic testing.
