Advances in the development of new and improved polymers have led many engineers and product designers to re-think their use of more traditional materials like metals in the manufacturing process. Parts once thought of as impossible to create using plastic, are now being designed with polymers at a higher rate than ever before.
Plastic has historically offered many advantages over metal. Plastic parts are lighter and afford more design flexibility. They tend to be less expensive than metals and need little if any finishing or additional assembly.
