Internal defect control: the key to creating high reliability Auto Parts /Alloy Steel Forged Parts

During the forging and processing process, tiny defects such as pores, cracks or inclusions may occur inside the component materials. These seemingly insignificant problems may cause component failure under high stress or harsh working conditions, thereby threatening the overall safety of the vehicle. Especially for key components such as drive shafts, suspension system brackets, engine connecting rods and differential parts, any small defects may lead to irreversible consequences.
Hansheng Machinery is well aware of the importance of internal defect control and has introduced a series of precision detection and control technologies to fundamentally solve this hidden danger and provide customers with safer and more reliable forging products.
Comprehensive defect control technology and process

Hansheng Machinery always regards the quality of raw materials as the primary link in internal defect control. During the procurement stage, the company strictly selects high-quality carbon steel, stainless steel, alloy steel and other materials, and uses a spectrometer to conduct detailed inspections on the composition of the materials to ensure that their composition is uniform and the impurity content is minimal.
During the forging process, the company uses advanced hot precision forging technology to accurately control the forging temperature, pressure and speed so that the metal flow inside the material fully fits the shape of the component, eliminates potential tiny gaps, and forms a high-density structure. This process is particularly suitable for the production of high-strength Auto Parts /Alloy Steel Forged Parts.
After forging, the parts need to undergo a rigorous heat treatment process to further optimize the metal grain structure and eliminate internal residual stress. Through this process, the fatigue strength and impact resistance of the parts are significantly improved.

To ensure the comprehensiveness of internal defect detection, Hansheng Machinery has introduced a variety of high-precision non-destructive testing equipment. For example, the wet magnetic particle flaw detector can quickly identify cracks on the surface and near the surface of the parts through magnetic field changes, the ultrasonic flaw detector can deeply detect the tiny gaps and cracks that may exist inside the material, and conduct in-depth analysis of complex parts to ensure that there are no hidden defects in the X-ray detection system.

For key components, the company is equipped with advanced three-coordinate measuring machines (CMMs), which can perform all-round dimensional inspections on parts to ensure that they are completely consistent with the design drawings. At the same time, the hardness of the material is strictly controlled by the hardness tester to ensure that the parts can still work stably in complex working environments.

Through strict internal defect control, the Auto Parts / Alloy Steel Forged Parts produced by Hansheng Machinery can maintain excellent performance under extreme conditions such as high temperature, high pressure and high stress, reduce failure rate and increase service life. In addition to the automotive industry, these technological achievements are also widely used in railways, engineering machinery, mining machinery and agricultural machinery, providing high-quality forged parts for multiple industries. With strict control of internal defects, Hansheng Machinery's products have won high recognition from global customers and become an important supplier of many internationally renowned automobile brands.

The success of Hansheng Machinery is not accidental, but stems from its continuous investment in technological innovation. The company has provided strong support for internal defect control technology by optimizing process flow, introducing intelligent manufacturing equipment and improving employee skills. The company has also established a complete quality management system, strictly implementing each production and testing process in accordance with ISO9001:2008 standards to eliminate defects from the source.
