Lost Wax Alloy Steel Casting in China

Specializing in the manufacturing of lost wax investment castings and machined parts in carbon steel and alloy steel, our company is a large-scale professional investment casting foundry with powerful machining capabilities in China. It consists of 2 major facilities, both steel casting foundry and CNC machining factory which enable us to supply precision castings parts with annual capacity of over 20, 000 tons, and the products are mainly exported to Europe, America, Japan and other destinations around the world. 

Our company was established in 1993, it covers a total area of about 40,000 square meters and has about 400 employees.The headquarters is located in the famous industrial town Yinzhou, Ningbo in China. It is very convenient to be reached with an advantageous geographic position; It is located about 40 kilometers away from the Bei-lun Port which is the second biggest port in China, and about 25 kilometers away from the Lishe International Airport. The casting base is located in Fenghua, Ningbo, a distance of 20 kilometers away from the Headquarters. the foundry is equipped with several types of energy-saving & environmentally-friendly production lines including automatic or semi-automatic production lines of key processes: wax making, shell making, pouring, heat treatment. The machining factory is located in headquarters and is fully equipped with complete and advanced CNC machining equipment including 30 vertical and horizontal machining centers, and more than 30 CNC machines and 50 other machining equipments., the machining facility is fully independent from the casting foundry and has an independent management team and tailored business model to suit. In addition to the casting, forging and machining, it also has the facility to machine various  profiles. Our company also has a lot of advanced inspection equipment, including Spectrometer, Metallographic Microscope, Tension Tester, Low Temperature Tester, X-ray Tester, MPT, UT, CMM, Video Measurement Machine and so on. With these advanced facilities & instruments, we are able to supply the high quality castings to our customers, and make products meeting comprehensive inspection requirements on chemical composition, mechanical properties, non-destructive testing and high precise dimensional inspections.

Our products cover a wide range of industries including train&Railway, automobile&Truck, construction machinery, mining machinery, forklift, agricultural machinery, shipbuilding, petroleum machinery, construction, valve and pumps, electric machine, hardware, power equipment and so on. We are capable to produce products according to customers' drawings or samples, we focus on both carbon steel and alloy steel. Up to today, more than 100 raw materials and 5, 000 kinds of different products have been developed and produced by us. We are familiar with the material standards of many countries, such as Chinese GB, American ASTM, AISI, German DIN, French NF, Japanese JIS, British BS, Australian AS and Association of American Railroads (AAR ) and other industrial standards.
