Do you want a better understanding of plastic materials, their properties, and their relationship to the mold design, injection molding process, and the finished part?

Plastic Materials is designed to give you a solid foundation for understanding polymer families, their corresponding material properties, plastic rheology, and shrink and warp characteristics.

Attendees will learn critical thought processes that help distinguish between the various root causes shrink and warp.



What Will I Learn?

We will begin with a discussion on creating polymers from monomers, followed by the importance of molecular weight to your part’s performance and processing characteristics.

Then, we dive into topics including drying, additives, viscosity, and rheology (study of plastic flow).
Attendees will learn what makes some polymers amorphous and others semi-crystalline, and how those classifications affect material properties, processing, mold design, and part design.

Finally, the course will take a deep dive into understanding and recognizing volumetric vs. orientation-induced shrinkage, and how each causes plastic parts to warp.

Attendees will take away practical strategies for reducing warp by evaluating options in material selection, mold design, processing, and part design.


How Long Is the Course?

The Plastic Materials Development Course is two days long.
