More than 10 years’ experience of designing and producing all kinds of precision machining parts. CNC Precision Machining Metal parts for customers overseas and domestically. Specialized in manufacturing products and components with tight tolerances and complicated shapes. OEM Ductile iron sand castings, lost foam casting, Vacum Moulding and so on,the moulding craft will be slected according to the actual tolerance request and demand quantity. Most of Our produced castings are used for valves, hydrants, pumps,trucks,railway and train and so on.   product presentation： The forging machine is used to produce plastic deformation by exerting pressure on the metal blank to obtain the forging with certain mechanical properties, shape and size.Through the continuous hammering of pipe fitting, the original segregation, porosity, porosity, slag and other compaction and bonding in the ingot become more compact, and the plastic and mechanical properties of the metal are improved.Forging pipe fittings mainly includes forging flange, forging reducing pipe, forging tee, etc.The main materials of forged pipe fittings are Q235, Q345, 16Mn,20#,35#,45#,40Cr,12Cr1MoV, 30CrMo,15CrMo, 20G, etc.With corresponding forging fittings is casting fitting, the mechanical properties of castings below forgings with the same material mechanical properties, casting pipe fittings metal melting into complying with the requirements of a certain liquid and poured into the mold, after cooling solidification, men get a predetermined shape, size and performance of the casting parts (or blank) process.[1]     company introduction： Hebei Mingda International Trading Company is a trading company which is specialized in castings,forgings and machinery parts.
