PLASTIC ENGINEERING

PLASTIC ENGINEERING encompasses the processing, design, development, and manufacture of plastics products. A plastic is a polymeric material that is in a semi-liquid state, having the property of plasticity and exhibiting flow.

Mechanical properties of plastics are often difficult to quantify, and the plastics engineer has to design a product that meets certain specifications while keeping costs to a minimum.
In PLASTIC ENGINEERING, as in most engineering disciplines, the economics of a product plays an important role. The cost of a plastic product is measured in different ways, and the absolute cost of a plastic material is difficult to ascertain.
Some plastics are manufactured from re-cycled materials but their use in engineering tends to be limited because the consistency of formulation and their physical properties tend to be less consistent. Electrical and electronic equipment and motor vehicle markets together accounted for 58 per cent of engineered plastics demand in 2003. Engineered plastics demand in the US was estimated at $9,702 million in 2007.
