Precision forging Lifting machinery accessories stainless steel flange cover Aluminum part manufacturing Hot and Cold Precision Forging Advanced Technology for Automotive Mining Aerospace Industries

Aluminum and aluminum alloys are the most widely used non-ferrous metals.

Precision forging forming technology (net forming) refers to the forming technology of the forging forming layer of the part, which only needs a small amount of processing or no processing to meet the requirements of the part. Precision forging forming technology is an important part of manufacturing technology and is also a widely used part manufacturing technology in the automotive, mining, energy, construction, aviation, aerospace, weapons and other industries. Precision forging forming technology not only saves materials and energy, reduces processing technology and equipment, but also significantly improves productivity and product quality, reduces production costs, and thus improves the market competitiveness of products.

According to different forming temperatures, precision forging processes can be divided into hot precision forging, cold precision forging, warm precision forging, composite precision forging, isothermal precision forging, etc.

1. Hot precision forging process? The precision forging process with a forging temperature higher than the recrystallization temperature is called hot precision forging. Hot precision forging materials have low deformation resistance, good plasticity, and are easy to form die forging.

2. Cold precision forging process Cold precision forging process is a precision forging process at room temperature. The cold precision forging process has the following characteristics: it is easy to control the shape and size of the workpiece and avoid errors caused by high temperature; the workpiece has high strength and precision and good surface quality.

3. Warm precision forging process The warm precision forging process is a precision forging process carried out at an appropriate temperature under the recrystallization temperature. The warm forging precision forming technology not only breaks through the limitations of large deformation resistance and not too complex part shape in cold forging, and the need to increase the intermediate heat treatment and surface treatment steps, but also overcomes the problem of reduced surface quality and dimensional accuracy due to strong oxidation in hot forging.

4. Composite precision forging process With the increasing complexity of precision forging workpieces and the improvement of precision requirements, simple cold forging processes cannot meet the requirements.

5. Isothermal precision forging process Isothermal precision forging process refers to the forming of billets at constant temperature. Isothermal die forging is often used for the precision forming of difficult-to-deform materials in the aerospace industry such as titanium alloys, aluminum alloys, and magnesium alloys. In recent years, it has also been used for the precision forming of non-ferrous metals in the automotive and machinery industries. Isothermal forging is mainly used for metal materials with a narrow forging temperature, especially titanium alloys that are very sensitive to deformation temperature.

① Produce precision die forgings and precision die forgings for finished parts.

② The production of precision die forgings, the main part of precision forgings, saves cutting processing, and some parts still require a small amount of cutting processing.

Advantages of precision die forging of aluminum alloy forgings

1. Greatly reduce the cost of product parts

Aluminum alloy forgings have small machining allowances, small tolerances, and small surface roughness values. Machining can partially or completely replace parts, save materials and machining time, and improve labor productivity.

2. Improve the mechanical properties and service life of products

The metal streamlines of aluminum alloy forgings are not cut off, and the distribution of streamlines is more reasonable. The strength of forgings is about 20% of cutting processing, with strong stress resistance, strong corrosion resistance, and long service life.

3. Suitable for parts with complex shapes, high performance, and expensive materials

These parts that are difficult to machine, consume a lot, are expensive, and precision die forging has obvious saving effects, such as gears, toothed parts, blades, aviation parts, electrical parts, etc.

4. There must be an appropriate batch

Precision forging is not economical in any case. Consider the batch, performance requirements, comprehensive cost and economic benefits of product production. The larger the batch, the better the benefit.
