Webinar Series

New for 2021! Kruse Training is launching a webinar series based on the successful “Cause-and-Effect Behaviors in Injection Molding” in-person seminars.  Join Torsten Kruse as he takes you through real-life molding scenarios to show the cause and effect behaviors of design and process. These webinars are offered every two weeks at no charge. Attendees will receive a downloadable syllabus for each webinar. Sign up today!

Currently available webinars: 

Molding Fundamentals: Temperature and Fill Speed

Part Design: Flow Restrictors

Date: Thursday, March 11, 2021
Time:
2:00 – 3:00 pm EST

Part Design Flow Restrictors ThumbnailLearn the basics of part design and how various design elements impact a molded part. Flow restrictors redirect and restrain material flow and allow for uniform filling patterns. This webinar covers issues such as air entrapment, flow hesitations, and race-track effects when using flow restrictors in part design. Download webinar syllabus
