Mechanical and Physical Analysis of Alloys Samples Produced with a New High Centrifugal Rate Machine

Abstract

A full review for technological processes used today, in dental prostheses industry for titanium casting, both in Europe and in United States, reveal that, there is no equipment available on the market able to cast small titanium parts in secondary inert vacuum by induction melting and centrifugal casting. All these advanced processes together contribute to an original concept of the Denticast System. The computer controlled cast sequence is another important factor contributing to a robust system, able to reproduce the achieved technological quality in a reliable manner. Mechanical testing (tensile and hardness) shows that the different alloys used in Denticast project and cast using the prototype, are in most of the results superior to those obtained with two different commercial systems (pressure-vacuum and centrifugal systems). The samples are usable for dental prosthesis without any risk for the patient health.
