According to mould, Fork toe can be divided into die forging and open die forging. Among them, open die forging is a process that produces forgings with certain sizes and mechanical properties through utilizing compact or pressure to freely deform metals on the up and down anvil face without any limits. It has simple equipment, low cost and good generality. Moreover, its forgings have simple shape and flexible operation. Therefore, open die forging occupies an important position in the production of heavy machinery and important parts.
 
However, many faults caused by various kinds of reasons usually happen in open die forging process so as to lead to the emergence of unqualified open die forgings such as forgings with cracks, chapped forgings, forgings with nonmetallic inclusion and blended or deformed forgings etc. As a result, the quality of forgings is affected and their production cost is increased as well. In order to avoid such cases happening, forging companies constantly strive to improve and develop open die forging process. The following has summarized several development directions of open die forging.
 
First of all, Wind Energy Parts with high precision and strength are badly needed. Based on this, the forging industry is trying hard to improve heating, increase purity of steel ingot and improve quality of liquid steel. Moreover, in order to optimize open die forging process and heat treatment, the forging industry is developing materials with high performance, which is accorded with the development of large open die forgings. The development of steel grades and requirement of steel purity are an important development direction of large open die forgings. Therefore, the forging industry is required to choose suitable forging materials and control quality of steelmaking source. In addition, standard and normative operation should be built.
 
Secondly, productivity is of great importance for an industry as well. If forging companies want to gain more profits, they must pay more attention on improvement of productivity. Open die forging must need machining. Precision milling machines are gradually put into use to increase efficient of back working procedure. What's more, through them, pass percent and joining ratio of open die forgings get improvement. In addition, continuous casting billets are applied in open die forging.
 
Thirdly, during the development of Forging parts supplier, environment protection should not be neglected. The forging industry spare no efforts to eliminate poisonous materials produced in the forging. Sewage begins to be discharged after heat treatment. Besides, for the purpose of lowering nose, mute press is put into use.
 
It's believed that with constant endeavor of forging industry, open die forging will get more rapid development and wider applications.
