Webinar Series

We are launching a new webinar series based on our Molding Defects lessons! Join Torsten Kruse as he explains various molding defects that can occur during the injection molding process and ways to prevent them. In each webinar you will learn how part design, mold design, and process impact molding defects and see the cause-and-effect behaviors of injection molding.

Our webinars are offered no charge and all attendees will receive a downloadable syllabus at the end of each session. Sign up today (sign-up form is at the bottom of the page).

Sink Marks and Voids-2 ThumbnailMolding Defects: Sink Marks and Voids (Part 2) 

Topics in this webinar include: various part design related challenges that impact the fill-to-shrinkage behavior of a molded part; the importance of evaluating and eliminating sink marks and voids prior to finalizing a part design; that injection pressure requirements may be dictated by sprue, runner, and gate sizes, but not necessarily by the wall thicknesses inside the molded part; and the way that polymer material cools inside the mold cavity may result in shrinkage and possible sink marks and void development.

Gate Blush and Halo ThumbnailMolding Defects: Gate Blush and Halo

Topics in this webinar include: the three primary reasons for gate blush; how gate types, sizes and locations determine blush and halo effects; if cavity filling velocity affects flow-induced shear stress and flow-induced residual shear stress; and why to compare residual shear stresses during the filling and packing phases.
