Precision Forging – with its natural advantages:
1- Near -Net Shape forging
2- Little machining or no machining need
3- Extra high Strenth and controlled sound internal structural
Precision Forging – Process Difference
- Hot Precision Forging :Materials for hot precision forging have low deformation resistance and good plasticity, making it easy to form relatively complex workpieces. However, due to strong oxidation, the surface quality and dimensional accuracy of the workpieces are relatively low. The commonly used process method for hot precision forging is closed-die forging.
- Cold Precision Forging is a precision forging process carried out at room temperature. The cold precision forging process has the following characteristics: the shape and size of the workpiece are relatively easy to control, avoiding errors caused by high temperature; the workpiece has high strength and precision, and good surface quality. During the cold forging forming process, the workpiece has poor plasticity and high deformation resistance, which places high requirements on molds and equipment, and it is difficult to form parts with complex structures.
- WarmPrecision Forging is a precision forging process carried out at a suitable temperature below the recrystallization temperature. The warm precision forming technology not only breaks through the limitations of cold forging, such as high deformation resistance, inability to form parts with overly complex shapes, and the need for additional intermediate heat treatment and surface treatment steps, but also overcomes the problem of reduced surface quality and dimensional accuracy caused by strong oxidation in hot forging. It simultaneously possesses the advantages of both cold forging and hot forging while overcoming the shortcomings of the two.
