The fracture splitting method is an innovative processing technique in the field of the automobile engine connecting rod (con/rod) manufacturing. Compared with traditional method, the technique has remarkable advantages. It can decrease manufacturing procedures, reduce equipment and tools investment and save energy. Hence the total production cost is greatly reduced. Furthermore, the technique can also improve product quality and bearing capability. It provides a high quality, high accuracy and low cost route for producing connecting rods (con/rods). The method has attracted extensive attention and has been used in some types of con/rods manufacturing. The process and its key factors such as materials, notches for fracture splitting, fracture splitting conditions and fracture splitting equipment are discussed in detail.
