Abstract
The invention discloses a method for manufacturing a handset oscillator, which comprises: tungsten-based alloyed powder is mixed with a caking agent at the temperature of 165 DEG C to 180 DEG C; the obtained mixture is formed into the blank of the handset oscillator by injection molding; ungrease treatment is carried out on the blank of the handset oscillator for removing the caking agent in the blank; then, the blank is sintered and prepared to obtain the handset oscillator. The method uses the metal injection molding technology to mold the handset oscillator for once, and the handset oscillator can be molded once. The manufactured handset oscillator does not need subsequent processing, and has high dimensional precision.
Description
A method for manufacturing a mobile phone vibrator technical field The invention relates to a method for manufacturing parts of communication equipment, more specifically, a method for manufacturing mobile phone vibrators. Background technique The mobile phone vibrator is usually produced by powder compaction molding process, that is, the tungsten-based alloy powder is put into the mold, formed under a certain pressure to form a compact, and then the compact is sintered at a high temperature to obtain a mobile phone vibrator. However, due to the large aspect ratio of the mobile phone vibrator, it is not easy to obtain a compact with uniform density, and the size may be distorted after sintering shrinkage, and the shape and precision of the product are difficult to control. Moreover, the mobile phone vibrator also has complex structures such as steps, and usually requires subsequent machining, with many and complicated processes.
