Precision forging machine manufacturers tell you that precision forging forming technology, also known as near-shape or near-net-shape technology, refers to the forming technology of mechanical components that only require a small amount of processing or no further processing after the parts are formed. Precision forging machine manufacturers tell you that in production practice, people are used to dividing precision forging forming technology into: cold precision forging forming, hot precision forging forming, warm precision forging forming, compound forming, occlusion forging, isothermal forging, split forging, etc.

1. Cold precision forging
Precision forging machine manufacturers tell you to directly forge unheated metal materials, mainly including cold extrusion and cold heading extrusion.
The cold precision forging forming technology is more suitable for multi-variety and small batch production.
2. Hot precision forging
Precision forging machine manufacturers tell you that it mainly refers to the precision forging forming process above the recrystallization temperature. Most of the hot precision forging forming processes use closed die forging, which requires high precision of the die and equipment. The blank volume must be strictly controlled during forging, otherwise it is easy to generate a large pressure inside the die. Therefore, when designing a closed die forging die, it is usually used. The principle of shunt pressure reduction is used to solve this problem.
At present, most of the straight bevel gears used in trucks in my country are produced by this method.
3. Warm precision forging
The manufacturer of the precision forging machine tells you that the precision forging process is performed at a suitable temperature below the recrystallization temperature. However, the forging temperature of warm forging is narrow, and the requirements for the mechanics of the die material and the die itself are high, and special high-precision forging equipment is usually required.
The warm precision forging process is generally more suitable for mass production, forging medium yield strength materials.
4. Composite forming
Precision forging machine manufacturers tell you that it is mainly to combine cold, warm, hot and other forging processes to learn from each other's strengths and make up for their shortcomings to achieve the desired effect.
Composite forming is a standard forging method for high-strength components such as various gears and pipe joints.
5. Block forging
It is a forming process of extruding metal in one or two directions by one or two punches in a closed die to obtain a precision forging without flash.
Precision forging machine manufacturers tell you that it is mainly used for the production of bevel gears, car constant velocity universal joint star sleeves, pipe joints, cross shafts, bevel gears and other products.
6. Isothermal forging
Precision forging machine manufacturers tell you that the billet is forged at a temperature that tends to be constant.
It is used for metal materials and parts that are sensitive to deformation temperature and difficult to form, such as titanium alloys, aluminum alloys, thin webs, and high ribs.
7. Split forging
The manufacturer of the precision forging machine tells you that a material shunt cavity or shunt channel is established in the forming part of the blank or mold to ensure the material filling effect.
Precision forging machine manufacturers tell you that split forging is mainly used in the cold forging forming process of spur gears and helical gears.
