Plastic manufacturing is the process of creating plastic products from raw materials, primarily derived from petroleum. The process typically involves heating and molding these materials into desired shapes using various techniques, such as injection molding, extrusion, and blow molding. These methods allow manufacturers to produce a wide range of items, from everyday household products to complex industrial components. The raw materials used in plastic manufacturing include polymers, which are long chains of molecules. Common types of plastics include polyethylene, polypropylene, and polyvinyl chloride (PVC). Once the plastic is formed, it can be further processed through techniques like cutting, assembling, and finishing to create the final product.
