Polymers Injection Molding, Process & Defects

This chapterDefects presents a theoretical background of polymers injectionInjection moldingMolding that will be provided to the students and clinch with practical activities. Mainly theoretical points to be discussed will be the origin and importance of this process in addition to the reasons why it’s so widely used. The work presents the main components of the machine, their function, and types. In addition, the chapter deals with the process stages and main parameters that must be considered and configured. To this point, students would be able to interact with the machine (under the instructor’s supervision); being able to identify previously mentioned machine components and process stages, inject some plastic pieces, and develop the next contents. Firstly, to identify some of the different marks that mobile parts of the machine left in the plastic pieces. Secondly, to find causes for main defects based on visual inspection. The main defectsDefects can occur on plastic parts because of a bad parameter’s configuration.
