What is the reason for the rebound of metal stamping parts during production? +15 years of experience, the manufacturer tells you

When we produce metal stamping parts, we often encounter the phenomenon of aluminum alloy rebound during stamping. What causes it? Xiaoshuo will work with you to understand: 1. The properties of aluminum alloy stamping shell raw materials are different in bending yield strength of different raw materials. The higher the yield strength, the greater the springback of the raw material. 2. Bending deformation, the greater the bending deformation, the greater the amount of springback, which is proportional to the two. 3. Mold structure and mold gap fit. A well-designed mold structure can reduce springback, and the mold should be designed and manufactured with a suitable gap. If the gap is too large, the springback will increase. 4. Bending the middle angle, the greater the value of the middle angle, the greater the amount of springback. 5. The structure of aluminum alloy stamping parts, the structure of the aluminum shell is different, and the amount of springback is also different. The more complicated the aluminum shell is, the greater the springback amount will be in one punching. Hardware, 15 years of craftsmanship focused on metal stamping parts, 20,000+ sets of customized mold production experience, daily production capacity of 3 million punching times, stamping accuracy up to 0.01mm, 16 quality inspections strictly for quality control. It can quickly solve the urgent problem of aluminum alloy stamping parts, solve the problem of stamping accuracy, and solve the problem of production quality. Choose, choose to rest assured!
