Designing for Plastics

Wednesday, July 19, 2017 @ 1pm

Join Xcentric Mold & Engineering and Amco Polymers for this educational webinar that focuses on designing for plastics. Material selection and features incorporated into your part will have a direct effect on the plastic injection molding process and final part quality.  In this webinar, you will learn how to design part features like:

  • – Draft Angles
  • – Wall Thickness
  • – Fillets and Radii
  • – Bosses
  • – Ribs
  • – Holes
  • – Shrinkage
  • – Gating
  • – Vents
  • – Knit Lines

Injection Molding Complex Parts


Adding Undercuts and Side Action without Sacrificing Speed


A side action is used in the mold to create undercuts in the custom plastic part. They allow design features like interlocking snaps and housing ports to be successfully molded. While undercuts add cost, they allow design engineers to keep the functionality of the designs intent.

In this webinar you will learn:

  • – Requirements for successfully molding with undercuts
  • – Challenges you may face when incorporating undercuts into your design
  • – Tips and tricks for using undercuts
