Injection molding is a manufacturing process used to produce plastic parts in large quantities. This is one of the most popular and comprehensive methods in the plastic industry.
The injection molding process starts with the creation of a mold or tool that contains a raw piece with the desired shape. The mold consists of two halves: a fixed half and a movable half that opens and closes.
The plastic material, usually in the form of pellets, is heated and melted into a liquid state. Then, the molten plastic is injected at high pressure through the feed channel into the mold cavity. The material fills the entire cavity and takes its exact shape.
After sufficient cooling time, the plastic in the mold hardens, allowing the piece to retain its shape when removed. The mold is then opened, and the molded piece is extracted using ejectors.
