Precision forging machine manufacturers tell you that precision die forging is a new process with little and no cutting developed on the basis of ordinary molds. It is to directly forge some parts of the parts that needed to be machined to meet the precision requirements in the past, or only need to leave a small amount of grinding. Therefore, the use of precision die forging technology requires stricter technical requirements for the relevant links of die forging, such as: control of blanking quality and surface quality; rational design of prefabricated blanks; less blank, no oxidation heating; heating Control of specifications and cooling specifications; control of precision forging die manufacturing and use; selection of suitable lubrication and cooling conditions, etc.

Precision forging machine manufacturers tell you that precision die forging has the significant advantages of saving metal and reducing cutting man-hours. However, due to the strengthening of the relevant links of die forging, some costs will increase. Therefore, whether a specific product is produced by a precision die forging process should be comprehensively considered according to the comprehensive economic indicators of the finished parts and the special requirements of the structure and performance of the parts.
Precision die forging is an advanced process to improve the precision and surface quality of die forgings. Precision forging machine manufacturers tell you that it can forge parts with complex shapes and high dimensional accuracy, such as bevel gears, blades, etc. Its main process features are:
1. The size of the original billet needs to be calculated, and the material is cut strictly according to the quality of the billet. Otherwise, the dimensional tolerance of the forgings will be increased and the accuracy will be reduced.
2. It is necessary to clean the surface of the billet to remove the oxide scale, decarburization layer and other defects on the surface of the billet.
3. In order to improve the dimensional accuracy of the forgings and reduce the surface roughness, no-oxidation and less-oxidative heating should be used to minimize the oxide scale formed on the surface of the billet.
4. Precision forging machine manufacturers tell you that in order to minimize oxidation and improve the quality of forgings, the heating temperature of precision forging is low. For carbon steel, the forging temperature is between 900 and 950 °C, which is called warm die forging.
5. The precision of precision die forging depends to a large extent on the machining precision of the forging die. Therefore, the precision of the precision forging die bore must be very high. Generally, the accuracy is two levels higher than that of forgings. Precision forging die forging manufacturers must have a guide post and guide sleeve structure to ensure accurate die clamping. In order to remove the gas in the die cavity, reduce the metal flow resistance, and make the metal fill the die cavity better, there should be vent holes on the die.
6. The manufacturer of Precision forging machine tells you to lubricate and cool the forging die well during die forging.
