Which parts of AI glasses use injection molding?

First of all, we need to recall the characteristics of injection molding - it is suitable for mass production of plastic parts with complex geometric shapes, with low cost and high efficiency. As a consumer electronic product, AI glasses must use injection molding for their shell structural parts.
Let’s first look at the most conspicuous parts of AI glasses: the frame and temples are definitely made of plastic, especially the ergonomic design with a curve, which is most suitable for injection molding. Decorative parts such as brand logo inlays and textured surface treatments also rely on mold accuracy.
Next is the internal structure of AI glasses: battery compartments with buckles and thin-walled features must be injection molded, sensor housings must be precisely wrapped around electronic components, and heat dissipation holes must also be molded in one go. There are also small and complex structural parts such as the fixing ring around the lens and the nose support bracket.
In addition, the interactive parts of AI glasses, such as the plastic base of buttons and touch panels, and the grille of microphones/speakers, all require high pore precision and must be made by injection molding. Even the lens substrate, if it is made of resin, may also be made by injection molding.
Summary: From the visible frames and temples to the internal sensor brackets, battery compartments, and precision acoustic grilles and optical fixtures, injection molding runs through the manufacturing of most plastic parts of AI glasses. Its core value lies in the high-volume precision manufacturing of complex structures at a very low unit cost.
