This month, in our series of FREE monthly SimTech™ webinars, we will explore the causes and solutions to a common injection molding problem called warp. Warp is caused by uneven shrinkage in different areas of the part. More common on parts that are mostly flat or with flat sections, warp is directly related to plastic cooling. If the cooling rate differs on each side of a wall, the warmer side will shrink more, creating warp. Our expert instructor, Todd Bryant will examine the affects on plastic that can cause warp and show you how to practice solving this problem utilizing our SimTech injection molding simulator.
Watch an animation explaining injection molding warp in a brief video clip from our popular online course, Injection Molding Part Problems & Solutions.
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:
- Problem solving warp as a part defect
- Identifying the root cause of warp
- Learn which of the “four plastic variables” affects warp and how to adjust it to fix the problem
- Learn how to use SimTech as a powerful learning tool so you can become a confident molder
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.
