There are many benefits to using injection molding over other manufacturing methods to produce plastic components. For example:

The following article provides an overview of plastic injection molding. It highlights what the process entails, key advantages of using it over other manufacturing methods, and challenges faced when conducting injection molding operations.

Many industries use injection molding to produce their parts and products. The process enables them to create components of various shapes and sizes in high quantities (i.e., thousands or millions of pieces) quickly, consistently, and cost-effectively. While it can be used with a variety of other materials (e.g., glass, metal, and rubber), it is most commonly utilized for plastic. For example, clear plastic is often injection molded to form personal protective equipment (PPE), such as face shields and goggles, for industry professionals.

The plastic injection molding process involves heating plastic (in pellet or grain form) until it has melted. The molten material is then injected into a closed two-part mold under high pressure, where it cools and solidifies. Once the material has fully hardened, it maintains the shape of the mold cavity. At this point, the mold can be opened so the piece can be removed and sent for further processing as needed.

While injection molding offers a number of advantages over other manufacturing methods, it also comes with some challenges, such as:
