Abstract. Stricter political regulations, increasing ecological awareness of society as well the pursuit for higher performance components motivate lightweight construction. Functional integration is one way to realize design, resulting in increased demands on component geometry. Sheet-bulk metal forming (SBMF) offers potential enable an economic and production functional through short process ...

Protraction headgears are commonly used in the treatment of Class III malocclusion characterized by maxillary retrognathism. The upward and forward rotation of the maxilla during protraction is a major unwanted side effect. The aim of this study was to eliminate the upward and forward rotation of maxilla while protracting. Seventeen patients with Class III malocclusion as a result of maxillary ...

The hydrostatic extrusion is a new method of extrusion process. The most important advantage of this method is reduction of friction and close tolerance for the coating thickness. In this study, the hydrostatic extrusion simulation of bimetallic wires has performed using of finite element method. In the following the advantages of hydrostatic extrusion compared to the direct extrusion are prese...
