Metal Injection Molding: Principle and Development
摘要
Abstract
Metal Injection Molding is an efficient and near net shape manufacturing technology, particularly suitable to the parts of small size and complicated shape. In this paper the status of Metal Injection Molding is first introduced. Formation principle as well as binder and powder choosing, powder processing, injection molding, degreasing and sintering is summarized. And technical characteristics and application of Micro Metal Injection Molding are presented. Limitation and development of this technologyare also discussed. It is considered that careful prefabrication of composite powder be helpful for homogenizinge composition during mixing and injecting, subsquently reducing distortion during sintering. New binders and new degreasing technologies should be developed to reduce residual binder. Injection molding of low binder, precision injection molding, and injection molding of tiny parts in a large scale should be developed.关键词
