Micro-injection Moulding of Polymer Locking Ligation Systems
Procedia CIRP, 2016 AbstractIn recent years, there has been an increment on micro-components for medical purposes, diseases treatment and surgical equipment, requiring biocompatible materials such as some engineering polymers. Nonetheless, the micro size of these parts impose challenges for fabrication using high production processes, like polymer injection moulding ...
