Shorts, Flash, Burns, Voids, Sinks, Warp, Weld Lines, Splay, Jetting, Flow Marks, Reduction in Mechanical Properties, and Residual Internal Stress. These common molding attribute problems and others will be the focus of this webinar. We will look at the root cause for each of these attribute issues and discuss how to address the root cause as a way of controlling the defect. This webinar will not only address the symptom but will look at the science behind the cure. To get the most out of this webinar attendees should have completed the webinar “Data Driven Cycle Development in Plastics Injection Molding” or have a mastery of decoupled molding theory. This webinar includes: 1. We have problems with voids or trapped air. How do we tell which defect we are dealing with?; 2. We routinely have random flow marks on our parts. What causes these flow marks?; 3. Our parts warp but not a consistent amount. What is happening and how do we control the warp?; 4. We have shorts (no fills) in the corner of our parts that pressure cannot pack out. Why?; 5. There are cosmetically unacceptable weld lines in our parts. How can we eliminate them?
