OPTIMIZATION TEMPERATURE AND FRICTION STENT PRODUCTION PROCESS BY EXTRUSION METHOD

Abstract

"The stent is manufactured by traditional machining methods. This study has been carried out to improve the mechanical properties of stents produced by removing swarf. Production methods have been examined and extruded to produce a seamless cylindrical section pipe. The Mg-Zn-XX alloy used in stent production was used in this study. Extrusion mold design is made to produce stent with Mg-Zn-XX alloy. These parameters are optimized because temperature and friction values from the Extrusion parameters affect the shaping parameters of the generated stent. During optimization, the Simufact finite elements program was used. The optimization has shown that the Mg-Zn-XX alloy has the best styling results of friction of 300 o C de Coulumb 0.4. "
