Webinar: How to Solve Weld Lines from the Plastics Point of View

This month, in our FREE SimTech™ series of webinars, we will explore weld lines and how they develop. As the plastic flows through the mold it forms a smooth and continuous flow front. If the plastic encounters a pin or other obstruction, the plastic flow front must split to form two flow fronts to go around the pin. When the two flow fronts meet on the other side the plastic rejoins forming a weld line. What are some strategies to avoid weld lines? Is it even possible? Our expert instructor, Todd Bryant will examine possible scenarios utilizing our SimTech injection molding simulator. 

Watch a brief video clip from our Injection Molding Part Problems and Solutions course showing weld lines.

 

You’ll get an inside look into the process from the “plastic’s point of view” as the foundation to all molding strategies. This means understanding the concept that all machine controls affect one or more of the four plastic processing variables. Paulson’s entire approach, from starting up a machine for a production run, to problem solving an existing run is to examine the situation from the “plastics point of view”.

Key Take Aways Include:

  • How to increase the strength and minimize the appearance of weld lines
  • Understand how to adjust plastic fill rates to minimize the formation of weld lines
  • How to use plastic behavior to your advantage when optimizing the molding process

Take part in this FREE webinar to learn and apply molding techniques that will dramatically change the way you process.

Special Guest: Donald C. Paulson

Newly inducted into the 2021 Plastics Hall of Fame(read more here), Donald Paulson is the founder and chairman of Paulson Training Programs, Inc. and the creator of the now widely accepted method of teaching plastic processing from the “Plastics Point of View”. Don will join this webinar and give his personal account of his years of research with the General Motors Institute that lead to transforming injection molding from an art to a science. An experience you won’t want to miss.
