Page 5 - Injection Molding Advanced Troubleshooting Guide
P. 5
Preface
Why a book dedicated to troubleshooting? The answer to that lies in frustrations
that the authors have experienced over the years in launching and maintaining
injection molds and processes for those molds. Have you ever experienced any of
the following?
High scrap rates
Excess down time
Slow cycle times
Customer rejections (both internal and external)
Processing around tooling issues
Damage to molds
Defects that seem to show up out of nowhere
Defects that keep reoccurring
“Fixed” problems that keep coming back
Molds that run fine in one machine but not in another
The goal of this book is to help provide tools and information that will help truly
address these types of concerns.
Often times in the plastics industry there is a great deal of learning through the
“school of hard knocks” and both of the authors have had the opportunity to learn
a lot this way. What the industry has not done well is passing along these lessons
to others. We have reached a point where we are interested in passing along the
lessons we have learned through experience in the trenches.
One thing that the authors have noticed in the industry is a disconnect between
processing and tooling. We come at troubleshooting with different backgrounds,
one in tooling and one in materials and processing. However, we both approach a
problem with the same thought process. We felt it was time to provide a resource
that dives deep into the interaction of tooling, processing, and materials and have
sought to create that in this work. There would not be a value in this book if
it was just regurgitation of the same information that has been documented in
