During Precision Shaft Die Casting Processing, how to prevent the generation of pores and inclusions to improve the quality of the shaft?

During the Precision Shaft Die Casting Processing process, preventing the generation of pores and inclusions is a key link to ensure shaft quality. The presence of pores and inclusions not only reduces the mechanical properties of the shaft, but may also affect its service life and reliability. Therefore, it is crucial to take effective measures to prevent these problems.
First of all, we must choose high-quality raw materials. The impurities and gas content in raw materials will directly affect the quality of die castings. By selecting metal materials with high purity and low gas content, the generation of pores and inclusions can be reduced from the source.
Secondly, strictly control the temperature and pressure during the die-casting process. Temperatures that are too high or too low can cause uneven metal flow, resulting in pores. At the same time, appropriate pressure can ensure that the metal fully fills the mold and reduces the formation of inclusions. Therefore, during the die-casting process, changes in temperature and pressure need to be precisely controlled to achieve the best die-casting effect.
In addition, the design and manufacturing of molds are also important factors in preventing pores and inclusions. The structure of the mold should be reasonable and the flow channel design should be smooth so that the metal can flow smoothly and fill the entire mold. At the same time, the surface of the mold should be smooth and defect-free to reduce the resistance generated by the metal during the flow process and reduce the probability of pores and inclusions.
Finally, strengthening quality inspection and subsequent processing is also an important means to improve shaft quality. During the die-casting process, quality inspections should be carried out regularly to detect and deal with problems such as pores and inclusions in a timely manner. At the same time, through subsequent treatments such as heat treatment and mechanical processing, internal stress can be further eliminated and the hardness and wear resistance of the shaft can be improved, thereby comprehensively improving the quality of the shaft.
To sum up, preventing the occurrence of pores and inclusions requires starting from many aspects such as raw material selection, die-casting process control, mold design and manufacturing, and quality inspection. Only by comprehensive consideration and taking corresponding measures can the quality of Precision Shaft Die Casting Processing be ensured to be stable and reliable.
