Glasses and plastic glasses how to distinguish
There is a metal core in the mirror legs of the plate, and the plastic is certainly not there; there is the mirror of the mirror by the other end of the screw, it has cut the texture; there is the plate of the nose is sticky, What can be separated out
Mainly from the material to distinguish
1. Plastic glasses refers to the plastic injection molding glasses, and the plate is the use of high-pressure molding and then cut into polished glasses frame
2. Glasses on the frame is a high-tech plastic memory sheet, usually cut from the processing of acetic acid fiber.
1, strictly speaking, their raw materials are basically the same, but the difference lies in the production process is different. Plastic glasses production process for injection molding, the first production mold, and then melt the plastic into the mold to form glasses frames. Is the first plastic through the compression process to form a sheet, and then through the NC machine tool cutting the formation of glasses frame, the density is higher than the plastic glasses, so the heavier weight, and more durable, easy to wear after deformation;
2, plastic glasses, the material is relatively low, and now very few people have worn, and the pattern is also called boring, not suitable for the pursuit of fashion young people choose.As the plate is the first form of glasses, so you can produce all kinds of Pattern, beautiful fashion, is the best choice for many young people. Table glasses and plastic glasses the difference between the glasses glasses not only light and will not cause skin sensitivity, the use of materials is environmentally friendly products, our skin more no side effects, Relatively wear, the disadvantage is not easy to heat processing adjustment.
Sheet and plastic are all ethylene products The so-called plastic glasses refers to the plastic injection molding glasses, and the plate is the use of high-pressure molding and then polished into the glasses frame frame frame high temperature, easy to break, deformation, can be a good protection lens; Another plate in the texture and wear comfort is far superior to the plastic infusion frame, so the general optical shop is the main push products. The plastic frame also has its own advantages, such as low cost, variety and so on, suitable for fashion owners often wear patterns for modeling, there are many joined the entertainment elements, such as Halloween mask glasses and so on to identify the main method is to observe Surface density, whether there is air bubbles, and in the end of the temple (near the frame) is the filling surface or cutting surface, frame frame and mirror legs whether there is a clear perfusion point (that is, similar to the plastic cup, 1-2mm small protrusions). Hope my answer to your satisfaction!
