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...

The article presents the application of total productive maintenance (TPM) to analyze the working time indicators of casting machines with particular emphasis on failures and unplanned downtime to reduce the proportion of emergency operation for preventive maintenance and diagnostics. The article presents that the influence of individual factors of complex machinery maintenance (TPM) is ...

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...
