Metal Injection Molding
A form of metalworking that uses finely-powdered metal and a binding agent to precisely "inject" metal in order to create complex and precise metal-based products in one operation. The feedstock, composed of metal and binding agent, are fed through plastic processing equipment. This allows otherwise complex and time consuming metalworking to be completed quickly and precisely, while maintaining, and occasionally surpassing, the durability of traditional metalworking. Metal injected molds are eventually transferred into a sintering stage where nitrogen or hydrogen gas are often used as an atmosphere in the sintering process.
