Sintering Support

During the debinding and high-temperature sintering processes, green parts shrink about 20%. At this time, the parts must be adequately supported to minimize the possibility for distortion. As metal injection molded parts are typically placed on flat ceramic plates or trays, as shown in Figure 13, it is ideal that they be designed with a large flat surface, or several component features that have a common plane, so that standard fixtures can be used. Parts that have long spans, cantilevers, or delicate points may need to be supported with part-specific fixtures or setters, which can be expensive to produce.
