Injection molding is a manufacturing process used to create parts by injecting molten material into a mold. This method is commonly used for producing plastic items, but it can also work with metals and glass. The process begins by heating the material until it becomes liquid, then forcing it into a mold cavity where it cools and solidifies into the desired shape. Once the material has cooled, the mold is opened, and the finished part is ejected. Injection molding is popular for its efficiency, allowing for high-volume production of complex shapes with precise dimensions. It is widely used in industries such as automotive, consumer goods, and electronics.
