Effect of material selection on the performance of the bent upper molds

In the field of metal processing, the performance of bending mold is directly related to processing efficiency and product quality. Material selection is one of the key factors determining the performance of bending. For example, the use of high hardness tool steel can significantly improve the wear resistance of the upper die and prolong its service life. According to ASTM standard, the hardness of tool steel is usually between HRC 58-62, so the hardness range ensures good shape accuracy and surface finish during continuous bending operation. In addition, the heat treatment process of the material is also crucial. Proper heat treatment can reduce the stress inside the material and improve its toughness, so as to avoid cracks when bearing high load. For example, the use of vacuum heat treatment technology can ensure that the material is evenly heated and cooled down, reducing the risk of deformation and cracks. In practical applications, the selection of suitable materials combined with advanced heat treatment technology enables the bending mold to show higher durability and less maintenance requirements when processing hard materials such as stainless steel.https://www.mhtcnc.com/product/bending-mold/
