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 under high pressure. Once the material cools and solidifies, the mold is opened, and the finished part is ejected. This technique is popular because it allows for high-volume production of complex shapes with precise dimensions. Injection molding is widely used in various industries, including automotive, consumer goods, and electronics, making it a crucial part of modern manufacturing.
