How is nylon formed into different shapes?

Nylon is formed into different shapes primarily through processes such as extrusion, injection molding, and blow molding. In extrusion, molten nylon is forced through a die to create continuous shapes like fibers or films. Injection molding involves melting nylon pellets and injecting them into a mold to create specific shapes, while blow molding uses air pressure to expand molten nylon into hollow forms. These methods allow for a wide range of products, from textiles to automotive parts.
