After a long period of development, the plate frame is no longer the dull style in the past, but has various colors and shapes; And because of its non-flammable, good gloss, beautiful style, non-allergic and other advantages and popular. It can be said that plate frames and titanium frames have become the mainstream of high-end glasses frames. But today's plate and frame market can be described as "mixed fish and dragons", and many inferior plates and frames in shopping malls are full of them.

First, judging the flat glasses frame from the material If you want to choose good flat glasses, you have to start from the roots-flat glasses are made of high-tech plastic memory boards. At present, most of the components of the board are acetate fibers, and a few high-grade frames are propionic acid fibers. Acetate fiber board can be divided into injection molding and press grinding. As the name implies, injection molding is made by casting with a mold, but at present it is mostly flat glass processed by pressure grinding. Generally speaking, French and Italian materials are better, and Japanese materials are not bad. Many medium and high-grade flat glasses are made of these high-quality plates, so the quality is more trustworthy. Good processing materials can not only make the glasses frame look comfortable and show its personality, but also become a unique decoration with strong functionality.

Second, judging the assembly process of the plate spectacle frame (1) from the process: the combination of plates with different colors and materials (2) carving process: according to the original colors and styles of the plates, various patterns are carved on the plate legs with a computer engraving machine; (3) Mosaic technology, that is, various patterns are embedded in the legs of the plate, which is seamless, does not damage the surface of the plate and is seamless. It not only subverts the traditional drilling mode, but also provides new ideas and new angles for drilling accessories. (4) stippling process: that is, the operator smears the paint on the temples with a stippling brush, so that the paint is uniformly attached to the board legs; (5) Etching process: use chemicals to change the color of the legs, such as changing from bright color to dim color. Of course, if we carefully observe the low-grade plate and frame, we will find that their technology is relatively simple, and generally do not use more advanced technologies such as splicing and mosaic. And high-grade plate and frame often use various techniques to create extraordinary colors and collocation.
