Precision Die Stamping Parts Co., Ltd., first select the raw materials and then provide good results

Precision Die Stamping Co., Ltd., the customer's choice to you, all hope that the supplier's products are qualified. Starting from the end, then we must first control the raw materials before production. What kind of raw materials are suitable? 1. High uniform elongation. In the tensile test, the elongation of the sample before the neck phenomenon begins to appear is called the uniform elongation. During deep drawing, the deformation of any area of u200bu200bthe sheet material cannot exceed the uniform extension range of the material, otherwise uneven deformation will occur. 2. Low flex-strength ratio. The ratio of the yield limit of the material to the strength limit is called the yield ratio. The low yield ratio can not only reduce the deformation resistance, but also reduce the tendency of wrinkling during drawing, reduce the amount of springback after bending, and improve the accuracy of the bending part. 3. Low work hardening. The work hardening that occurs after cold deformation will increase the deformation resistance of the material and make it difficult to continue to deform. Therefore, plates with a low hardening index are generally used. However, the material with high hardening index has good plastic deformation stability (that is, the plastic deformation is more uniform), and it is not easy to appear localized cracks. 4. In actual production, process tests similar to the stamping process are commonly used, such as drawing performance test, bulging performance test, etc. to check the stamping performance of the material to ensure the quality of the finished product and a high pass rate. Hardware, 15 years of ingenuity focused on precision die stamping parts Co., Ltd., 20000+ sets of mold custom processing and production experience, monthly 100+ sets of mold processing capacity, daily production capacity of 3 million punches, stamping accuracy up to ±0.01mm, 16 quality The inspection layer is strictly for quality control. It can quickly solve time-critical problems, stamping accuracy problems, and production quality problems for you.
