The 4M Approach: Molding Process. Mold. Machine. Material.
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 (4Ms) as possible sources of part defects. Importantly, the interaction between tooling, processing, and material is emphasized, allowing successful resolution of difficult problems where other by-the-book approaches fail.
Starting with troubleshooting methodology and tools, this book focuses on key areas that impact troubleshooting, in particular the 4Ms. This is followed by an in-depth troubleshooting guide for various molding defects, structured logically by type of problem/solution. Insightful case studies throughout the book 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 from the authors, who have built strong reputations in the field, this book serves as an ideal reference to be consulted at the machine, suitable for both beginning and experienced molders.
With valuable information on robust process windows, cycle time evaluations, scrap savings, and runners/gates, no other book provides the unique insights found here.
