This book provides a user-friendly guide to the implementation of Scientific Injection Molding, a proven methodology to ensure robust and reliable mass production of plastic parts.Readers will gain a clear understanding of their machines and especially their condition and behavior through on-site tests, of the polymers that will be processed, and of the necessary equipment for the application of this methodology in production plants. All the tests and tools that Scientific Injection Molding proposes are explained in detail so they can be readily applied.Performing the validation of a mold or process correctly, establishing the limits of the process window or molding area through the design of experiments, and transferring processes from one machine to another, assuring their repeatability, are skills presented as fundamental tools of the modern injection molder.Content:1 Scientific Injection Molding - Advanced Steps toward Implementation2 Knowing Our Machines3 Knowing the Reliability and Performance of Injection Molding Machines4 Understanding Plastic Materials5 Required Information for Defining the Process6 Necessary Equipment for Advanced Injection Molding7 Tools for Scientific Injection Molding8 Top Ten Key Parameters in the Definition of the Injection Molding Process9 Process Portability, DOE (Design of Experiments), Mold Qualification and Process Validation10 Melt Preparation11 Process Variability, Self-Adaptation, and Corrections12 Data To Be Collected for the Calculation and Performance of a Scientific Injection Molding Process Methodology13 Reference Data Tables
