Silica-sol investment casting and CNC machining, from our own foundry in Shandong. Valve bodies and pipe fittings are our certified line, not a sideline.

ISO 9001:2015 · TUV Rheinland Casting 10 g – 50 kg +/- 0.1 mm 200 t / month
One number worth knowing before you ask for a price.
Duplex and nickel alloys are quoted by heat weight, not by piece count. Our smallest furnace is 150 kg, so a light order still carries a full heat. If your quantity is small, tell us the piece weight and we will tell you honestly whether it makes sense.

2205 and 2507, plus 6% Mo grades for marine and chloride service.

Nickel alloys

625, 825 and C276 for corrosive and high-temperature duty. Priced by heat weight.

Low-alloy & heat-resistant

Low-alloy and high-temperature grades for general valve and fitting bodies.

About the certificate scope

We hold ISO 9001:2015 issued by TUV Rheinland, certificate number 01 100 1430766, valid from 16 April 2026 to 15 April 2029, first issued in 2011. The scope is written as precision casting of valves up to DN300 and manufacturing of pipe fittings up to DN300.

We quote inside that scope. If your part sits outside it, we will say so at the quoting stage rather than after the order.
