Precision Forging  - SK is a precision forgings manufacturer and supplier from China

SK forging group invested in technology and equipments to improve the level of precision forging. In 2006, SK forging group invested 50 million build a new professional precision forging company. The annual production capacity is 5000 tons of precision forgings. The precision forging products of SK were provided to the China Aerospace Group, First Tractor Group, General Motors and so on.

What is precision forging?

Precision forging is an alternative process to replace the traditional forging complex parts.  For example, if the connecting rods do not use precision forging, they need the complicated machining processes to achieve the final shapes. The use of precision forging could achieve the IT8 ~ IT10 tolerance level easily. As precision forging without flash, it not only save the time to cut the flash, but also saves the material of forgings flash.  

Features of precision forging

1. Precision forging and closed die forging have the basic same working principle. The difference is that precision forging has higher requirements on the surface, dimensional tolerances and shape. The precision forgings usually need less machining or without machining.

2. As a process of a one-time forming, precision forging need precision Size, weight and shape on forging blanks. 

Materials used for precision forging

Precision forging is belongs to the hot forging. The materials of precision forging are same with other hot forging processes. Precision forging could forge a variety of types of materials. The most common materials are carbon steel, alloy steel, stainless steel and copper alloy. SK could forge the materials from United States, Japan, Germany, Australia and Italy. 

Applications of precision forgings

Precision forgings are mainly used in the key components of aircraft, power generation equipment, tubing components and automotive which have the high requirements on surface quality.  Some parts do not use precision forging, usually use die forging and machining process.
