Metal Injection Molding (MIM) is a technology developed from a combination of polymer injection molding and powder metallurgy, The mixture of metal powder and polymer that perform as a binder is injected into the mold to produce the desired shape. The advantages of thes technology lie in production of small components, such as bio-chemical and dental tools, gun components, electrical, and automobile parts, because of its ability in producing high quality and complex shape products in large scale. After burning out the polymeric binder, powder metallurgy processing will give a near net shape product, reducing time and expenses in machining, material and energy lost, and it is particularly suitable for fabrication of materials with high melting-point (e.g. stainless steel, titanium, tungsten alloy, ferrous alloy and ceramics). MIM process involves 4 stages: mixing, molding, debinding, and sintering. Debinding is most importance stage as a long processing time is needed, during which the binder must be removed form molded part without leaving and significant defects by properly control fo debinding parameters. Proper conditions are required for the better process which uses less time and still producing high-quality products. Since binder is used in mixing stage up to debinding stage, binder's properies affects the products in every stage of production. Therefore, a study in binder compositions and their characteristic in MIM process is essential in order to acquire quality products. This study will concentrate at the effects of binders and it debinding characteristics Hopefully, the appropriate composition and condition for MIM process will be obtained and the result of this study will provide required information for the employment of MIM in our industry.
