Influence of injection molding parameters on injection molded part weight

Polymeric materials processing is one of the fastest growing industries in the world. One of the most important method for processing polymeric materials is injection molding. The characteristics of the process (mass production of wide variety of products from very simple one to extremely demanding, the possibility of achieving high productivity with very little or no additional finishing operations), make it a very interesting and important cyclical polymeric materials processing procedure. A large number of injection molding parameters affects the performance and productivity of molding part. As part of the paper, the samples of polystyrene (PS 495N Nature) were made by adjusting various parameters (packing pressure, packing pressure time). Afterward, the weight of obtained specimens were analyzed. The mathematical models that show dependence of part weight on the injection molded parameters were obtained as the result of analysis.
