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
Date: Thursday, February 25, 2021
Time: 2:00 – 3:00 pm EST
Begin with the basics! Learn what happens inside a mold during the injection molding process. This webinar covers how to evaluate a part in the cooling phase by comparing wall thickness and process set-ups based on the results from injection pressure requirements, clamp tonnage curves, and part weight curves.

Polymer Materials: Overview
Date: Thursday, March 4, 2021
Time: 2:00 – 3:00 pm EST
Learn the fundamentals of polymer material behavior and how different plastics behave during the injection molding process. This webinar covers the different classifications of polymers and their key characteristics, the basics of polymer creation, including monomers, chain molecules and side branches, internal bonding mechanisms, both including both primary and secondary forces, and the microstructures of amorphous and semi-crystalline materials.

Part Design: Flow Restrictors
Date: Thursday, March 11, 2021
Time: 2:00 – 3:00 pm EST
Learn 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
Upcoming webinars (dates and times coming soon):
Mold Design: Gate Symmetry and Balance
Learn the basics of part design and how various design elements impact a molded part. This webinar covers: the importance of symmetrical gate design, how gate placement affects injection pressure and packing pressure distribution, how fiber orientation is impacted by gate placement, and how gate symmetry and balance can improve the overall shrinkages and flatness of a part.
Mold Design: Balancing Multi-Gated Runner Parts
Learn the basics of part design and how various design elements impact a molded part.This webinar covers: the factors to consider when implementing a multiple gating strategy, how different runner dimensions impact filling behaviors and injection pressures, how to analyze tracer result to see behind the flow-front of a part filling, and how to use a “runner design sensitivity test.”
Mold Design: Mold Steel Selection
Learn the basics of part design and how various design elements impact a molded part. Topics in this webinar include: the most common mold steel materials and what attributes they should possess; the best mold steel options for different polymer materials, injection pressures, and production cycles; temperature distribution behavior for molds with different mold steels and mold components.
Processing: Pressure Behavior
Learn the fundamentals of process optimization by understanding how different phases in the injection molding cycle will influence the overall part quality. Topics include: how melt and mold temperatures impact injection pressure during the filling phase, how viscosity curves can predict temperature and injection behavior, and how different fill times affect injection pressure during filling.
Processing: Polymer Flow During Packing
Learn the fundamentals of process optimization by understanding how different phases in the injection molding cycle will influence the overall part quality. Learn how to: modify filling-to-packing switch-over points and packing profiles, understand the predominant polymer packing flow path by evaluating tracer results, melt core, packing pressure and clamp tonnages, and volumetric shrinkage development.
Processing: Understanding Shrinkage and Warpage
Learn the fundamentals of process optimization by understanding how different phases in the injection molding cycle will influence the overall part quality. Topics covered in this webinar include: the causes of shrinkage and warpage in injection molded parts, how part design variations affect volumetric shrinkages and resulting part warpage, how part design, mold design, cooling behavior, polymer characteristics and processing steps affect shrinkage and warpage behaviors.
Molding Defects: Jetting
Learn about the causes of common molding defects and how to prevent them. Topics in this webinar include: how and why jetting occurs during filling; causes and preventative measures for jetting development; how gate location could either be the cause of or the solution for jetting and air entrapment; and how injection flow velocity impacts jetting behavior.
