Injection molding is a manufacturing technique where raw materials, often in the form of plastic pellets, are heated until molten and then injected into a pre-designed mold cavity. After cooling and solidification, the mold is opened, and the finished part is ejected.

It is widely used for creating high-volume, complex, and precise parts made from materials such as plastics, metals, elastomers, or glass. This process is highly efficient for mass production, offering quick turnaround times and consistent quality.
