Rapid changes and specialization in technology make it increasingly difficult for designers to keep track of the current capabilities of manufacturing processes and choose the appropriate one. Improper process selection leads to higher costs, lower quality and wrong choice of supplier. Currently, there is no software advisory system to help the design/procurement personnel in process and suppli...

At present, the qualified rate of large thin-walled magnesium alloy castings is low. In this study, effects mold structure and process parameters were investigated to improve production qualification castings. The filling die was simulated by numerical simulation technology optimize their structure. On basis an optimized structure, using a response surface model, group optimal combinations obta...

occlusal rest (Fig. 5, B), and guiding planes (Fig. 5, C). If there are voids or irregularities, they are filled with monomer and powder with a paint brush. 9. Try-in the removable partial denture (Fig. 6) to ensure a proper adaptation of the resin coping (Fig. 7). The die spacer can be removed from the tooth with a cotton pellet soaked in die spacer thinner. Rinse the tooth several times befor...

Rheo-forming is becoming the choice for production of high quality parts with diminished defects and fine integrity. In this paper, the novel self-inoculation rheo-diecasting (SIRD) process, in which semisolid slurry is produced by mixing two precursory solid and liquid alloys and subsequently pouring them through a multi-stream fluid director, has been proposed. Microstructural characteristics...
