Photonics Dictionary

injection molding: Injection molding is a manufacturing process used to produce parts by injecting molten material into a mold. It is widely used for creating a variety of plastic products, but it can also be used with metals, glass, elastomers, and confections. The process involves several steps:

Clamping: The two halves of the mold are securely closed using a clamping unit.

Injection: Molten material (usually plastic) is injected into the mold cavity through a nozzle by an injection unit. The material is forced under high pressure to fill the mold completely.

Cooling: Once the molten material fills the mold, it begins to cool and solidify into the shape of the mold cavity. The cooling time depends on the material and the thickness of the part.

Ejection: After the part has sufficiently cooled, the mold opens, and an ejection mechanism pushes the part out of the mold cavity.

Resetting: The mold closes again, and the process repeats for the next part.

Injection molding is favored for its ability to produce large volumes of identical parts with high precision and repeatability. It is used in various industries, including automotive, consumer goods, electronics, medical devices, and packaging. The main advantages of injection molding are high production rates, complex geometry capabilities, a wide range of material choices, and low labor costs per part.
