Course Overview

The ability of a plastic component to function properly for its expected life is dependent upon an accurate assessment of the application requirements and the ability to align those requirements with a material that has the appropriate properties. The design of the part, the material selected to make it, and a sound approach to processing the material, all play a crucial role in determining the life of the product. When parts do fail, a systematic process must be undertaken to arrive at a root cause and solutions should address this root cause in order to be successful over the long term. Understanding the interaction between design, material properties, and the manufacturing process is made more difficult by the fact that available material properties are typically inadequate in capturing long-term performance considerations.

This course will combine an in-depth understanding of plastic material behavior at the fundamental level with the techniques and tools that are used to diagnose, correct, and prevent product failures. It will illustrate the shortcomings in the industry’s current methods of evaluating plastic material properties and provide alternatives that give the in-depth understanding needed to design and produce parts that perform to requirements.
