PIM Technology
Process of injection molding feedstock mixed with metal/ceramic fine powder and binder, followed by debinding and sintering. Technology for manufacturing complex-shaped net-shape or near-net-shape parts.
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
