Description

Injection molding device

The present invention relates to a molding apparatus, and more particularly to an injection molding apparatus.

In recent years, with the development of multimedia, the demand for optical components mounted on laptops, videophones, and mobile phones has become greater and greater. As this demand increases, the optical component itself is required to be further miniaturized and low in cost. For optical components such as microlenses, light guides, etc., the molding process is usually injection molding. Injection molding can greatly improve production efficiency and output, and reduce costs.
