50% MIM components are covered by electronic instrument industry in Asian

Metal Injection Molding (MIM) is a near net forming technology which is suitable to produce the components with micro size and three dimensional complex shape and special performance.

Metal Injection Molding (MIM) is developed by the integration of traditional powder metallurgy technology and modern plastic injection molding technology,the basic process is: Firstly, mixing variety of fine metal powder (less than 20μm generally) with preset binder (various thermoplastics,paraffin and other materials) according to a certain proportion evenly,then the feed stock with flowing property can be made;Secondly,the feed stock would into the mold cavity (or multiple mold cavity)by injecting,then the green part can be shaped; Finally,by degreasing and high temperature sintering,various metal components with well-proportioned micro structure and high density can be finished.

The Injectamax company and BASF company,which are from the United States and Germany respectively have shorten the degreasing time from dozens of hours to a few hours and have improved the performance of maintaining shape of the binder obviously.Also the precision of the component has been enhanced from + 0.5% to + 0.3%. After the 21st century,the MIM technology has been further improved,the new materials and technology have emerged constantly,and the industrialization has developed rapidly. With the strength of complex shape,small size and large output,it is widely applied to many industry fields,such as the light type weapons parts,watches parts,hand-operated tools,orthodontics brackets,automobile engine parts,electronic sealing parts,cutting tools and sports equipment.

Electronics instrument industry is the main application field for MIM technology,covering about 50% sales of MIM components in Asian marketing.The miniaturization of electronic devices demands the component with lower production cost and better performance and smaller size,so MIM component can give full play to its advantage.
