PLASTIC MATERIAL PROPERTIES & SELECTION PROCESS
COURSE INTRODUCTION
Plastic parts range from simple devices to complicated test equipment and implants. Plastics in engineering are used more and more for weight, cost, and performance purposes. This workshop will discuss plastics used in the injection molding process for medical, automotive and audio industries. The first section will review the general composition of plastic materials which will include the materials added to the basic polymers. The second section will discuss many factors that contribute to the plastic selection. The final section will review the chemistry and the application of most common plastic materials.
