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.
