Injection Molding of Plastics from Agricultural Materials
OBJECTIVE DOE Chicago Operations %ice The objective of this research was to conduct a systematic study to relate injection molding parameters to properties of blends of starch and synthetic polymer. Blends of normal (25 % amylose) and high amylose (50 and 70% amylose) corn starch (containing between 60 and 70 % of the mixture by weight) and synthetic polymer were used in this research. Two diff...
متن کاملExperimental and Numerical Investigation of Thickness on the Shrinkage and out of Roundness in Cylindrical Parts in Injection Molding Process
Injection molding process is one of the most important methods of forming in the plastics manufacturing industry. Shrinkage and out of roundness are phenomenons that affect the final product quality. In this study, the effect of the thickness of cylindrical parts from polypropylene material on shrinkage and out of roundness has been investigated. For this purpose, injection molding process is s...
متن کاملA Recurrent Neural Network for Warpage Prediction in Injection Molding
Injection molding is classified as one of the most flexible and economical manufacturing processes with high volume of plastic molded parts. Causes of variations in the process are related to the vast number of factors acting during a regular production run, which directly impacts the quality of final products. A common quality trouble in finished products is the presence of warpage. Thus, this...
متن کاملDynamic of Taking out Molding Parts at Injection Molding
E. Ragan, J. Dobránsky, P. Baron, M. Kočiško, J. Svetlík, Technical University in Košice, Slovakia Most plastic parts used in automobile production are manufactured by injection molding. Their quality depends also on taking out molding and on the manipulators for it. Task of this contribution is to theoretically describe a transport of molding at taking out after injection molding in relation o...
