Injection Molding Troubleshooting Guide, 3rd Ed.

Book excerpt: The IM Troubleshooting Guide was originally prepared in 1996 as a 48 page convenient pocket sized resource for use in Injection Molding. This information is most useful by personnel who work in the injection molding field including press operators, technicians, engineers, etc. This 3rd ED is at 104 pages and includes selected extra pages from other APEBOOKS that are helpful in process set up and troubleshooting.This book includes many useful definitions and tips for troubleshooting molding problems -- both process and tooling related. The book was written based on many years of process engineering. The solutions for correcting process problems are listed in the best order to solve the problem based on factors such as ease & timeliness to perform versus cost to implement and always considering effectiveness to solve problem. It is also useful to identify a common set of definitions for each department to use when discussing these common molding defects. Tips are often provided as to which defects may be process correctable versus those requiring product or mold changes.An introduction to DOE and dimensional nominalization is made, but discussed in greater detail in some of the other booklets written by this author for injection molding ... these are listed later in this book ... a total of six books have been written for injection molding.
