Micro PIM Technology
Technology combining LIGA process (high-precision micro mold manufacturing) and PIM (powder injection molding), manufacturing micro-sized (ultra-compact) parts with high precision. Fine powder and binder are mixed, injection molded, and then undergo debinding and sintering processes.
Complex 3D shapes and high aspect ratio structures are achievable.
LIGA + PIM hybrid process enables fine teeth and ultra-precision sidewalls (very low surface roughness)
Minimizes post-processing compared to conventional machining
Micro grippers, linkages, joints for surgical robots, Robotic-Assisted Surgery, robotics and precision equipment, high-value electronic packaging markets such as 5G and electric vehicle thermal management parts
