Professor Cohen received an Excellence in Teaching Award for his course on polymeric materials based on this textbook. His research interests focus on the structure-property relationships of elastomers and the testing of theories of rubber elasticity and fracture. Previous research efforts were devoted to the study of suspensions and their applications. He was a co-principal investigator of the Cornell Injection Molding Program initiated under a grant from the National Science Foundation (NSF) and supported by an industrial consortium until 2000. 

With a computer program, which solved Eqs. (5) and (7) for We by numerical method, Weber numbers were obtained from layer to layer for each injection molding operation. The calculated points were then connected to curves, depending on the normalized thickness. Figure 17 shows these theoretically deduced Weix)... 

Write a ID FEM program using 2-noded tube elements to balance complex runner systems in injection molding. Compare the simulation to the runner system presented in Chapter 6. 

Failure to validate processes that cannot be fully verified by subsequent inspection and test, as required by 21 CFR 820.75(a). For example, the complaint handling software program, ultrasonic sealing procedure, leak testing procedure, and injection molding procedure have not been validated. 

To get even wall thickness throughout the container, just like for extrusion blow molded containers, the preform must be programmed to put additional polymer where the most stretch will occur. Since the core and the cavity of the injection mold are fairly permanent, one cannot make changes on the fly as one can in extrusion biow molding. Therefore, the designing must be done upfront.
