Abstract
A manufacturing process using microwave for thermal debinding according to the invention is mainly applied in manufacturing process of powder metallurgy. Wherein, metal powder is mixed polymer materials such as adhesives, fillings or lubricants, and a body is formed by means of molding, forging, extrusion, injection or scraping. The body to be debinded is placed in a microwave environment in an exposed manner or covered with powder, and power and work time of microwave are set for rapidly heating and debinding the body. The manufacturing process according to the invention is capable of accelerating manufacturing procedure, economizing production cost, reducing defects, quickly drying and rapidly removing polymer materials.
