Within medical production there is a need for small size, high precision, low weight and high strength components. This work describes an alternative to the existing time and material consuming machining process of such components. A micro forming device with controlled heating up to 450°C and high precision guiding is developed. The magnesium alloy AZ31B is analysed by compression and the flow stress and formability are determined as function of strain, strain rate and temperature. A component for dental purposes is formed at varying temperature and the results in kind of load displacement curves and fracture are discussed with respect to the material test carried out

Abstract
Within medical production there is a need for small size, high precision, low weight and high strength components. This work describes an alternative to the existing time and material consuming machining process of such components. A micro forming device with controlled heating up to 450°C and high precision guiding is developed. The magnesium alloy AZ31B is analysed by compression and the flow stress and formability are determined as function of strain, strain rate and temperature. A component for dental purposes is formed at varying temperature and the results in kind of load displacement curves and fracture are discussed with respect to the material test carried out
