In some applications, such as grilles for automobiles, engineering plastics such as PET compete with SMC and also with some metals such as zinc, which can be cast or even injection-molded. What would be the three inherent advantages of each of the material types in this kind of application?
What will be an ideal response?
PET: cost, production time, and processability SMC: strength, durability, and equipment costs
Zinc: weatherability, appearance, and marketability
