Lesson 6: Deformation Behavior

Plastic part designers have an abundance of polymer materials to choose from, ranging from commodity to technical or engineered polymers. Selecting the optimal material for each design is key to a successful molding project. In this lesson we will focus on deformation behavior of various polymers.

This lesson covers deformation behavior of amorphous materials and semi-crystalline materials, how to reverse PVT curves to evaluate what happens to polymer materials during the heating phase, and how to compare reversed PVT curves with modulus curves.

Goals of Polymer Materials: Material Behavior (Level 1): 

  • Learning the fundamentals of polymer material characteristics and basic polymer categorizations
  • Get a basic understanding of how different material behaviors will impact the molding process and the final molded part
  • Analyze real-life molded parts and learn the cause-and-effect behaviors of design and process

Section Description: 
Part and mold designers need to understand not only design principles but also the fundamentals of plastics. The choice of plastic or polymer strongly impacts the outcome of a molded part. A general understanding of the basic properties and structures of polymers will help part and mold designers and processors make choices and decisions that will optimize the final part.

This section covers explanations, simulations, cause-and-effect analyses, and the introduction of various polymer material properties. It evaluates and analyzes the relationship between different polymers and their behavior during molding. The optimal polymer material for each design is key to a successful molding project.
