Stainless steel stamping parts, so that the stretched products are more qualified

Stainless steel stamping parts are widely used and are loved and recognized by most customers. Also because of its more processing technology, all aspects of performance are compared with other metal materials, which are more beautiful in appearance, high in wear resistance, and so on. So what issues need to be paid attention to in the stretching process? 1. Some deep-drawn parts have high requirements for surface quality, such as stainless steel products, automobile outer coverings, etc., if the blanks with pits or scratches are used for deep drawing, these defects will remain in the products without exception. On, or even enlargement (such as scratches), it will have an adverse effect on the subsequent process and increase the cost. 2. Stainless steel materials are not easy to be drawn due to their high tensile strength and severe work hardening, especially if they need to be drawn multiple times. A lot of practice shows that the material thickness anisotropy index R and hardening index n values u200bu200bgreatly affect the ultimate drawing coefficient of the material. 3. The larger the R value and the n value, the better the drawing performance of the material. Like austenitic stainless steel (such as 304), the n value is large, and it is easy to form the irregular shape of the sink, but the R value is not as large as that of low-carbon steel, so the ultimate drawing coefficient is not as good as that of low-carbon steel. Although some ferritic stainless steels have a higher R value than austenitic stainless steels (such as 304), the n value is lower and the drawing performance is not good. In short, the deep drawing of stainless steel has its particularity, and it is generally not suitable to draw too deep, otherwise it will be easily broken. Hardware, 15 years of craftsmanship focusing on stainless steel stamping parts, skilled cooperation experience in more than 20 industries. 20000+ sets of mold custom processing and production practice, stamping accuracy can reach 0.1mm, daily production capacity of 3 million punching times, and 16 quality inspections are strictly controlled. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve mass production quality problems.
