Sheet is not a material, but a material form

In fact, the sheet is not a material, but a material form. Steel plates, iron plates, aluminum plates, wood boards, and plastic plates can all be called plates. In the eyeglass frame, the frame is different from other plastic frames in the manufacturing process. Plate holders are more commonly used with acetate (some of which are propionic acid fibers) as the main component. After milling, milling, milling, turning, milling, finishing, polishing, surface treatment, printing, etc. The process is processed, the production process is complicated, and the cost is high.

 

The sheet metal frame is 100% resistant to ultraviolet light, and the density is generally higher than that of the injection molding frame, so it is relatively heavy and durable, and is not easy to fade. At the same time, because it is formed into a plate first , it not only has a heavy and metallic texture, but also can produce a wide variety of products. The pattern and color are more easily interpreted than the monochrome injection molding frame, which is very popular among people. In the daily selection, we can identify the sheet frame by the following aspects.

1. Usually, the injection molding frame will produce obvious traces of the lines in the joint of the mold, commonly known as the split line, generally at the center of the edge of the mirror and the temple. The sheet is not.

2. The nose pad of the plate frame is transparent and colorless. No matter what color the frame is, the nose pad of the plate frame is transparent, and the fake frame of the injection molding material is because it is integrated. Color, or transparent color that is not transparent.

3. The gloss of the sheet glasses frame is very good and soft. The counterfeit sheet metal frame has a good gloss, but the light is not the same (sinus light).

4. The transparent plate glasses frame has a wire inside the temple, and the counter plate plate frame does not.
