Plastic manufacturing is the process of creating plastic products from raw materials. It typically involves melting down plastic pellets and shaping them into desired forms using various techniques such as injection molding, extrusion, or blow molding. These methods allow manufacturers to produce a wide range of items, from everyday household goods to complex industrial components. The raw materials used in plastic manufacturing often include polyethylene, polypropylene, and polyvinyl chloride (PVC). These materials are derived from petroleum and natural gas. Once shaped, the plastic products can be further processed, decorated, or assembled to meet specific requirements for different applications in industries like packaging, automotive, and consumer goods.
