In forging, pressure can be applied to metal blanks to plastically deform OEM forgings and change their mechanical properties. The looseness of the metal can be eliminated by forging. Holes to improve the mechanical properties of forgings.

What is the scope of OEM forgings?

① OEM forgings for general industry refer to civil industries such as machine tool construction, agricultural machinery, agricultural tool manufacturing and warehouse industry.

② OEM forgings for hydrogenerators such as main shaft and intermediate shaft etc.

③ OEM forgings for thermal power plants such as rotors, impellers, locking ring spindles, etc.

④ Metallurgical machinery such as cold rolling, hot rolling and herringbone gear shafts.

⑤ Forged parts for pressure vessels, such as cylinder body, boiler ring flange and head, etc.

⑥Marine OEM forgings such as crankshaft, stern shaft, rudder shaft, thrust shaft and intermediate shaft etc.

OEM forgings

What are the application advantages of OEM forgings?

1) Large weight range. OEM forgings range from a few grams to hundreds of tons.

2) Higher quality than castings. The mechanical properties of OEM forgings are better than those of castings and they can withstand large impact forces and other heavy loads. Therefore, forgings are used for all important and heavily stressed parts. For steels with high carbide content, OEM forgings are of better quality than rolled material. For example, rolled products made of high-speed steel can only meet the use requirements after forging. Milling tools made of high-speed steel in particular must be forged.

3) Lightest weight. Under the premise of ensuring structural strength, OEM forgings are lighter than castings, which reduces the weight of the machine itself, which is of great importance for vehicles, aircraft, vehicles and spacecraft.

How to measure the quality of OEM forgings?

(1) Geometry and size

Generally, the outer dimensions of OEM forgings are tested with measuring tools such as steel rulers, calipers and stencils; Die forgings with complex shapes can be precisely inspected by cracking.

(2) Surface quality

Cracks, pressure points and folding defects on the surface of OEM forgings are usually visible to the naked eye. Sometimes the cracks are very small, and if the depth of the fold is unknown, it can be observed after cleaning the shovel; If necessary, the fault detection method can be used for testing.

(3) Internal organization

Whether there are cracks, inclusions, looseness and other defects in the OEM forgings, the macroscopic structure of the forging section can be checked with the naked eye or with a 10-to-30-fold magnifying glass. The method commonly used in production is acid etching testing, i.e. the sample is cut out of the part of the forging to be tested, and the defects of the macro-structure on the section can be caused by acid solution etching, such as the distribution of forging streamlines, cracks and inclusions.
