Injection molding is an economical and very efficient method of producing injection mold parts. It can produce millions of parts with exactly the same shape, dimension, and quality. Some examples of injection molded parts are the mobile phones, mouse, keyboard, and many components found inside the automobile. molding is a manufacturing method used in the plastics and polymers industries to create hollow but strong containers for their clients. Plastic beverage bottles and fuel tanks are commonly created through blow molding. A typical blow molding machine set-up uses an extruded plastic preform and compressed air to fill the chamber of a divided mold. The two halves of the mold separate and the finished container is released.
Although many products are manufactured using the blow molding process, it might be simpler to examine what happens to one particular product — a standard two-liter soda bottle.
