Fabrication and Quality Evaluation of Micro-gear by Metal Powder Injection Molding

摘要

This study describes the methodology on fabrication and quality evaluation of the micro-gear manufactured by metal powder injection molding (MM). Cross-sections of the gear teeth are observed with a digital microscope and dimensions of teethes were measured by an image analysis. The variation in dimensions of teethes in a piece of micro-gear and between micro-gears was compared. It was shown that those experiments contribute useful information on the quality of the micro gear.
