碩士 === 龍華科技大學 === 機械工程系碩士班 === 107 === To qualify the final molded products are approved & doable for the Lab, We can find out the best molding parameter for quality to improve the plastic and tooling feature. We are searching POM material for the mechanical gear parts, It was included teflon20%, excellent lubrication & chemical resistance, & the highest impact strength, It has a deformation & circularity stability, We can use Taguchi Method Lab flow chart L9(34), to in-put molding-injection process, Then use Optical Vision Measure to read dimensions data after lab completed. We can add Lab data into Taguchi Method for analysis, then we can get a excellent deformation & circularity combination, for example The injection 10sec, holding pressure, cooling time 35sec, barrel temperature 205°C, Based on this molded parameter will get a best SN evaluation. Then we can use best deformation & circularity data to proceed with SN evaluation to proof , deformation reading 69.692, Actual SN reading 68.820, circularity evaluation reading 26.538, Actual SN reading 26.153, We finally can find out the deformation and circularity SN evaluation will very close to the actual SN evaluation. We can provide this excellent mechanical properties for the company reference, also the Taguchi Method with all data analysis can be follow for the future new products applications.
