The combination of rigidity and flexibility, the beauty of metal fiber materials

When a wire rod with the thickness of the little finger has undergone numerous cluster drawing, annealing, solid solution ... The length of the drawn metal fiber can go around the earth once. Metal fibers are thinner than hair, but still have the inherent performance advantages of high elasticity, high bending resistance, and high tensile strength of metal materials. At the same time, they can also have some special properties of non-metal fibers to meet wider application needs. Compared with other organic or inorganic fibers, metal fibers have higher mechanical strength, high temperature resistance, corrosion resistance, and better electrical conductivity, thermal conductivity and sintering properties. As a result, metal fiber-based composite materials have shown broad application prospects in the fields of electronics, chemical industry, machinery, military, textile, food, medicine and other industries. 1 Textiles Metal fibers can be used in various textiles after being processed into composite materials or yarns. The metal fiber fabric has the characteristics of anti-radiation, anti-static, high temperature resistance, and has both softness and elasticity. Metal fiber textiles can be used for high temperature resistance, antistatic, electromagnetic shielding and other applications, such as mold cloth for automotive glass production, electrostatic brushes for printers, anti-static work clothes, anti-electromagnetic shielding maternity clothes, etc. 2 Filtration After the metal fiber is sintered, a high-performance filter medium, the metal fiber sintered felt, will be formed. Its high porosity is suitable for fine filtration applications: increasing efficiency, saving operating costs, and reducing environmental pollution. Compared with traditional filtration, the metal fiber filter material has higher flow rate, strong dirt holding capacity, long online life, easy cleaning and processing. Therefore, it is widely used in polymer filtration, filtration of fuel, lubricating oil and hydraulic oil, as well as high temperature flue gas filtration and HEPA filtration, etc. 3 Conductive plastics Metal fibers are added to plastic composites to make the perfect filler material. It can protect electronic products from electrostatic discharge, prevent plastic parts from discharging and shield electromagnetic interference. This technology simplifies the process of plastic molding. It can be molded in one shot, and high-quality products can be obtained without secondary processing. In addition, metal fibers can achieve high-efficiency EMI shielding and ESD protection functions with only a small amount of addition, which not only saves costs, but also provides a safe, healthy and environmentally friendly solution.

What are the reasons for the blockage of blanking holes in precision stamping

What are the reasons for the blockage of blanking holes in precision stamping

When the stamping material in precision stamping is soft and magnetic adsorption material, the larger the size of the blanking step hole of the punching die is, it is easy to induce lateral frictional resistance, which eventually leads to the blockage of the blanking hole.
