[0002] In the traditional production process of safety belt mandrel, the forming techniques commonly used include casting, forging and machining. These techniques have their own advantages and disadvantages in the manufacturing process, but as the demand for industrial production increases, they have gradually exposed some shortcomings. Casting is a common metal forming method, which pours molten metal into a mold and allows it to cool and solidify to form the desired shape. However, due to the slow cooling speed of the material during the casting process, it may cause holes and cracks inside the material, affecting the quality of the product. In addition, the castings usually need subsequent machining to achieve the required precision and surface roughness, which increases the production cost and time. Forging technology deforms the metal at high temperature by applying external force to obtain the required shape and performance. Although forging can improve the density and mechanical properties of the metal, its equipment and process are complex, the skill requirement of the operator is high, and it is difficult to realize complex shape design. Mechanical processing relies on cutting tools to remove material to form the desired shape. Although this method has high precision, the material utilization rate is low, the production efficiency is relatively low, and the cost is high.
