How to control the dimensional accuracy of automotive forgings?

How to control the dimensional accuracy of automotive forgings? Please give an actual production example and write an article.

Automotive forgings are an indispensable part of automobile manufacturing, and their dimensional accuracy plays a crucial role in the performance and quality of the entire vehicle. The dimensional accuracy of automotive forgings is usually influenced by various factors such as material and processing technology. Therefore, manufacturers need to take various measures to control these factors to ensure that the parts’ dimensions meet requirements.

Let’s take the example of an aluminum alloy wheel hub produced by an automotive component supplier to explain the specific methods for controlling the dimensional accuracy of automotive forgings:

  1. Design reasonable molds: The shape and size of automotive forgings are determined by molds, so designing molds that meet requirements is essential. In this case, the company uses high-precision CNC machining centers to manufacture molds and comprehensively checks and evaluates them to ensure that the molds’ dimensions meet design requirements.
  2. Select the appropriate heating process: The correct forging temperature and speed are key factors to ensure the part’s dimensional accuracy. In this case, the company uses low-temperature heat treatment technology and fast solidification strengthening technology to achieve fine control of the dimensions of the aluminum alloy wheel hub with high smoothness, low concentricity, good size stability and high wear resistance.
  3. Precision machining: Precision machining is an important link to ensure the dimensional accuracy of automotive forgings. In this case, the company uses high-speed CNC machining centers for post-processing and checks and evaluates each processing step to ensure that the part’s dimensional error is within an acceptable range.
  4. Quality control: Effective quality control is a key factor to ensure that the produced forgings meet dimensional requirements. In this case, the company adopts a mature quality management system, including advanced inspection equipment and complete process control, to ensure that the dimensional accuracy of automotive forgings meets standard requirements.

In conclusion, controlling the dimensional accuracy of automotive forgings requires using various methods and comprehensively considering the influence of factors such as materials and processing technology. In actual production, manufacturers need to use suitable equipment and technology, establish a mature quality management system, and strictly monitor and inspect each link to ensure that the dimensional accuracy of automotive forgings meets requirements.
