This highly practical troubleshooting guide solves injection molding problems systematically
and quickly. The rigorous but user-friendly approach employs the authors' proven »STOP«
methodology considering molding process mold machine and material (4M's) as possible
sources of part defects. Importantly the interaction between tooling processing and material
is emphasized allowing successful resolution of difficult problems where »by-the-books«
approaches fail. Starting from troubleshooting methodology and tools there is a focused
discussion of key areas impacting troubleshooting in particular the 4M's followed by an
in-depth troubleshooting guide for various molding defects structured logically by type of
problem solution. Insightful case studies throughout show the strengths of the STOP method to
get real processes to run smoothly and reliably producing quality parts with optimal cycle
time and cost. Drawing on a wealth of hands-on experience this book serves as an ideal
reference to be consulted at the machine or as a learning and training manual suitable for
both beginners and experienced molders. With valuable information on robust process windows
cycle time evaluations scrap savings and runners gates with no existing standard in the
