To create a 90 degree bend on 4mm thick acrylic, heat bending is used, while for 2mm thick tin sheet metal, a metal brake is employed. Plastic water bottles are made via blow molding, and water hose pipes are produced through extrusion. Each method is designed to suit the material's properties and the desired final product.
