The density of tungsten alloy is very high, the maximum density is 18.6g/cm3. High density can exhibit a smaller volume than other materials under the same weight. And this kind of product requires a lot of weight and a small volume, such as mobile phone vibration, vibrating parts of clocks, etc. Tungsten alloy materials can just meet the needs of such products. Compared with other materials, the tungsten alloy vibrator has the advantages of precise weight, non-magnetic, high temperature resistance, oxidation resistance, and corrosion resistance. The tungsten alloy mobile phone vibrator uses advanced metal injection molding technology. Metal injection molding process and thermoplastic material (such as plastic or paraffin, etc.) mixed metal powder, plastic compression molding process on the injection molding machine. A new type of powder metallurgy near-net forming technology formed by the introduction of metal injection molding process into the field of powder metallurgy. The basic process is: firstly mix the solid powder and the organic binder uniformly, after granulating, inject it into the cavity of the mold under heating and plasticization (~150℃), and then use chemical or thermal The decomposition method removes the binder in the formed blank, and finally obtains the final product through sintering and densification. Compared with the traditional process, it has the characteristics of high precision, uniform organization, excellent performance, and low production cost.
