Using Polymers as the Main Material in Engine Blocks and Components

Namata S

A substance which has a Molecular structure built up chiefly or completely from a large number of similar units bonded together, e.g. many synthetic organic materials used as plastics and resins. Plastics are very often used to quickly develop models in the automotive industry. A plastic prototype of a rocker arm can be created with 24 hours whereas a full metal model would take up to months and cost several times greater than then the plastic model. Rapid prototyping cuts the time factor in a manufacturing environment significantly and when time is cut so is the cost. The last and most important thing about plastics is that they are extremely recyclable. They are much easier to recycle than typical metals
