Look at any product near you right now, and you will realize that all manufactured hard products have a specific shape or are made up of parts of different shapes. The shape of many products we use is determined by the type of mold used to produce it. The mold-driven production of specific metal and non-metal products in different shapes requires different sophisticated tools attached to a press. This tool shapes products using pressure. The tool that determines the shape of the finished part is called a mold. Molds can be categorized into two main classes: plastic and non-plastic. For instance, to produce a car bonnet or other metal body parts, you would use a non-plastic mold. On the other hand, you would use a plastic mold to create the shell of a printer. Injection molding is the process of manufacturing plastic parts using molds. The plastic or synthetic material is heated to a melting point before the liquid material is transferred into the mold. As the material cools down and hardens, the required shape is formed. Injection molding is suitable for firms that want to manufacture a large number of identical parts. Even though the process is commonly used when producing plastic products, it can also work with other materials like rubber, glass, and metal.
