plastics manufacturing

Plastics manufacturing involves transforming raw materials, typically derived from oil or natural gas, into plastic products through processes like polymerization, where small molecules (monomers) are chemically linked into long chains (polymers). These polymers are then melted and shaped through methods such as extrusion, injection molding, or casting to create films, containers, or parts. Additives may be mixed in to enhance properties like strength or flexibility. The finished plastics are cooled, cut, or assembled into final products, playing vital roles across industries including packaging, automotive, medical devices, and electronics.
