Tungsten alloy mobile phone vibrator

Tungsten alloy has a very high density, with a density of 18.6g/cm3. High density can show a smaller volume than other materials at the same weight. This kind of product requires a lot of weight and a small size, such as mobile phone vibrations, clock vibration parts, etc. Tungsten alloy materials can exactly meet the needs of such products. Compared with other materials, tungsten alloy vibrators have the advantages of precise weight, non-magnetism, high temperature resistance, oxidation resistance, corrosion resistance, etc. Tungsten alloy mobile phone vibrators adopt advanced metal injection molding process. Metal injection molding process is a process in which metal powder mixed with thermoplastic substances (such as plastic or paraffin) is molded on an injection molding machine. The metal injection molding process is introduced into the field of powder metallurgy and is a new type of powder metallurgy near net shape forming technology. The basic process is: the solid powder and organic binder are uniformly mixed, and after granulation, they are injected into the mold cavity with an injection molding machine in a heated and plasticized state (~150°C) to solidify and form, and then chemical or thermal The decomposition method removes the binder from the parison, and finally the final product is obtained through sintering and densification. Compared with traditional processes, it has the characteristics of high precision, uniform structure, performance and low production cost.
