Micro Injection Molding

Overview

The manufacturing of precise plastic parts requires a complete understanding of design, processing, and metrology, aspects of the injection molding process. Micro injection molding is the technology used to manufacture plastics products characterized by tolerances in the micrometer range, or dimensions in the micrometer range, or by the presence of micro-and nano-features on their topography. Main applications are in the field of biomedical devices, electronics, and sensors. This course will provide a comprehensive overview of precision injection molding processing technologies, covering all aspects of machines, mold design, processing, and parts characterization. The attendees are expected to end the seminar with a complete understanding of this technology's potential in several fields of application and practical information that could be implemented to support product development.
