The aim of this study is to design, manufacture and test a tool of indirect extrusion for preform forming. This preform will be employed in subsequent operations for the manufacturing of dental implants. Parts produced by this particular formation process are capable of higher functioning mechanical properties and metallurgical characteristics. Commercially pure titanium Gr 4 is the material used in the preform. For the definition of the preform to be constructed, an identification was performed of the dental implant on the basis found in the technical literature. A characterization of the titanium based on the flow curve, metallographic analysis and microhardness was also performed. Initially, a tool was designed (tool proposal) based on calculations of force and work. The tests exhibited specific deficiencies, principally concerning the need for reduced dimensional features. Following this test, based on the needs described, an improved proposal tool was developed to align the tool and the punch during job execution. The results of the test exhibited dimensional symmetry featuring an alignment of the tool guides, as well as a uniform displacement of the punch during indirect extrusion.
