Ribs & Webs
Ribs and webs are an efficient way to increase your part strength, and minimize the effects of dimensional variation caused by the substantial shrinkage, which occurs during debinding and sintering. As with plastic injection molding, ribs and webs also improve the molding process and provide better dimensional control. Fig. 18 details how ribs and webs can be added to improve the mechanical design and provide a more robust MIM component.
Another application of ribs is displayed in Fig. 19, where they are used as a means to provide coring for part mass reduction without effecting the intended end use or strength of the component.
