In fact, the plate is not a material, but the material form, steel plate, iron plate, aluminum plate, wood board, plastic plate can be called plate. In the spectacle frames, the frames are different from other plastic materials in the production process. Plate racks are more commonly used acetate fiber (some propionic acid fibers) as the main component material, through the milling machine for the inner car, milling slot, outside the car, milling and milling, setting, polishing, surface treatment, printing, etc. more than 100 Processed from the road, the production process is complicated and the cost is high. Plate racks are 100% resistant to ultraviolet light, and the density is generally higher than that of injection molding racks, so they are relatively heavier and more durable and do not fade. At the same time, since they are first formed into sheets, they not only have heavy and metallic texture, but also produce a wide variety of Patterns and colors are more easily interpreted than monochromatic injection frames and are loved by people. In our daily selection, we can identify plate frames through the following aspects. 1. Usually the injection molding rack will produce obvious line marks at the joint gap of the mold, commonly known as the distribution line, generally at the edge of the mirror surface and temples, while the plate does not have 2. The nose pads of the plate glasses frames are transparent and colorless. No matter what color the frame is, the nose pads of the plate frames are transparent, and the frame of the counterfeit injection material is one of the talents so the nose pads are Color, or transparent color. 3. The gloss of the plate frames is very good and soft. Counterfeit plate plate glasses frame gloss is also good, but the light is not the same (thief light). 4. There is a wire inside the temple of the transparent plate spectacle frame, and the counterfeit spectacle frames are not.
