| Summary: | 碩士 === 國立中央大學 === 機械工程學系 === 107 === In general, the conventional superplastic molding process, because the molding takes too long, leads to non-economic benefits, and in order to find a better process method to solve this problem, this paper proposes for Quick Plastic Forming (Quick Plastic Forming, QPF) 's process, coupled with the idea of pre-punching-assisted preforming for metal phone casing molding, is expected to shorten the time required for this process and break through to become a more economical process.
This study uses general commercial AA5083 -O Aluminum quick phone shell molding blown to blown molded plastic Fast explore, compare and analyzethe pre-stamped added auxiliary blowing plus pre-press and generally no faster assisted molding process capability, making phone analyzes whether more on the edge of the shell.
The results of the study show that there is a rapid plastic forming using pre-punching, because a shape close to the finished product has been pre-punched, and then blown, which saves the time required and does not require a stepped blowing pressure. Blowing out the finished product we need is more time-optimized than the fast plastic molding without pre-punching aid.
