Polymer processing refers to the methods used to shape and form polymers, which are large molecules made up of repeating structural units. Common techniques include injection molding, extrusion, and blow molding. These processes allow manufacturers to create a wide variety of products, from plastic containers to automotive parts. During polymer processing, heat and pressure are often applied to make the material pliable. Once shaped, the polymer is cooled or cured to maintain its new form. This versatility makes polymer processing essential in industries such as packaging, construction, and consumer goods.
