Micro PM
WANTS proprietary technology combining the economic efficiency of powder metallurgy (PM) and the high-density complex shape realization of PIM. Performs fine powder mixing, molding, and sintering processes by applying Modal Hybrid Powder (composite powder control).
Secures high density and mechanical properties + excellent cost competitiveness
Balance of shape freedom and productivity
Cost reduction and quality innovation compared to MIM/PM
Minimizes post-processing work
Ultra-compact precision parts such as U-SIM Tray, Laptop Hinge, Guitar String Parts, ultra-compact mechanisms for smartphones and wearable devices
