Abstract: High-strength titanium alloy hinge components with complex geometries were fabricated using metal injection molding. The dimensional characteristics of these components were systematically evaluated under various processing conditions utilizing optical and three-dimensional imaging instruments. This study investigated the influence of degreasing methods, part orientation, molding techniques, and binder systems—specifically plastic-based and wax-based binders—on the dimensional accuracy and shape stability of the components. The results demonstrate that green parts produced with plastic-based binders exhibit higher mechanical strength, reduced deformation during the debinding process, and improved dimensional stability after sintering compared to those utilizing wax-based binders. In contrast, wax-based green parts showed significant dimensional deviations during debinding, primarily due to swelling phenomena. However, dimensional precision can be further enhanced by optimizing part orientation and adjusting the surface roughness of sintering plates. Ultimately, through the use of sintering fixtures and post-molding reshaping treatments, the dimensional accuracy of MIM-fabricated titanium alloy components can be controlled within ±0.1%.
