Webinar: How to Solve VOIDS from the Plastics Point of View

Is there a void in your life? Or in the parts you’re molding? Then join us for this month’s FREE webinar topic, “How to Solve Voids from the Plastics Point of View.” As part of our series of FREE monthly SimTech™ webinars, we will review the nature of voids. Voids, aka vacuum voids, are areas in the part, usually in thick sections, where there is no material. They look like air bubbles but almost never are. Plastic shrinks as it cools. That shrinkage can occur uniformly, on the outside of the part (sink marks), or on the inside of the part (voids). If a part has thick sections and is aggressively cooled in the mold then the surface appearance can be normal, but the plastic has to shrink somewhere and that is often internally, resulting in a void. Structurally, voids can be acceptable with no great effect. Of course, if the part isn’t clear you can’t see them unless you cut the part open. Join our expert instructor, Todd Bryant as he examines the effects on plastic that can cause voids and show you how to practice solving this problem utilizing our SimTech injection molding simulator.

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 voids as a part defect
  • Identifying the root cause of voids marks
  • Learn which of the “four plastic variables” affects voids 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.
