Overview
NEWLIFE Tungsten Vibrator Weights are precision-engineered components designed for micro vibration motors used in smartphones, wearables, and haptic devices. These weights leverage high-density tungsten alloys developed in-house and manufactured through Metal Injection Molding (MIM) and precision powder metallurgy (PM) processes, delivering maximum mass in minimal volumes. Compared with conventional brass or steel counterweights, tungsten allows significantly smaller components while providing stronger vibration output, enabling compact device designs without compromising performance.
The PM/MIM approach allows tight dimensional tolerances, near-net-shape production, and minimal post-processing, reducing both material waste and machining costs. NEWLIFE's proprietary powder formulations ensure consistent density, mechanical strength, and surface finish, which are critical for the repetitive, high-frequency motion of micro motors. Advanced surface finishing and plating options enhance wear resistance and corrosion protection, ensuring reliable operation over millions of vibration cycles.
Tungsten's high density enables precise tuning of the vibrator's mass and CG placement, which is essential for high-fidelity haptic feedback in compact electronics. The versatility of PM/MIM also allows customization of shapes for cylindrical, coin-type, and specialized micro-actuators, enabling designers to integrate weights into unique motor geometries without sacrificing performance.
