Q. Plastic part manufacturing process?

Plastic belongs to the family of organic materials. Organic materials are those materials which derived directly from carbon. They consist of carbon chemically combined with hydrogen, oxygen and other non-metallic substances, and their structures, in most cases, are fairly complex. The large and diverse organic group includes the natural materials: wood, coal, petroleum, natural rubber, animal fibers and food, which have biological origins. Synthetics include the large group of solvents, adhesives, synthetic fibers, rubbers, plastics, explosives, lubricants, yes, soaps and cutting oils etc. which have no biological origins. Of them, plastic and synthetic rubbers are termed as "polymers".
