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): 

  • Learn 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: 
It is important for part and mold designers not only to understand design principles, but also to understand the fundamentals of plastics. The choice of a plastic, or polymer, has a strong impact on the outcome of a molded part. Having a general understanding of the basic properties and structures of polymers will help part and mold designers, as well as processors, make choices and decisions that will optimize the final part.

Explanations, simulations, cause and effect analyses, and the introduction of various polymer material properties are covered in this section. The relationship between various polymers and how they behave during the molding process are evaluated and analyzed. Selecting the optimal polymer material for each design is key to a successful molding project.
