Surface polishing of acetate glasses is a very important process in the manufacturing process of acetate glasses.
After the sunglasses manufacturers take the frames out of the drum, they will have scratches on the surface and some pits on the surface during subsequent processing. Polishing can polish and polish the places where the hands are scraped around the acetate frame and the places that are not smooth enough. It can maximize the brightness of the board.
1. The main function of eyewear polishing
After the acetate frames are taken out of the drum, there will be scratches on the surface during subsequent processing, and there are still pits on some surfaces. Polishing can polish the scratched areas and areas that are not smooth enough around the plate rack and can maximize the improved brightness of the board.
2. Classification of eyeglasses polishing
1. Coarse throwing: slower speed
2. Fine polishing: faster speed
Our technicians can use one transmission device for both coarse and fine polishing. Therefore, operators only need to swap the polishing wheel, such as switching between hemp wheels and cloth wheels, to complete coarse or fine polishing.
3. Types of materials for sunglasses polishing
1. White polishing wax: made of calcium oxide, a small amount of magnesium oxide, and adhesive; the particle size is small and not sharp, and it is easy to weather and deteriorate after long-term storage. Mainly polished metal and plastic with a softer texture.
2. Red polishing wax: made of iron oxide, aluminum oxide, and adhesive; the hardness is equal. Polishes generic metal and plastic.
3. Green polishing wax: made of magnesium oxide and adhesive, hard and sharp, with strong grinding ability, for polishing hard alloy, stainless steel, and other materials.
The choice of polishing wax is based only on the material of the polished part. After the polished parts are polished, there will be residues and dirt from the polishing wax on the surface, which can be cleaned with detergent.
4. Acetate eyeglass polishing process
Frames and temples are dry-thrown and wet-thrown, respectively. After being assembled into a frame, wet throwing is performed.
1. Use a cloth wheel for dry polishing
The material is ordinary transparent tape. Stick the transparent tape onto a rectangular block, coat the cloth wheel with glue, and polish the plate frame.
2. Vibrate after dry throwing.
Wet throw after shaking. The abrasive used for wet polishing is sand powder.
After the frames and temples complete the above procedures respectively, our technicians inspect the parts, fit hinges, and manually trim them to form a complete frame.
3. Finally, our technicians carry out wet polishing on the entire frame.
After the frames and temples complete the above procedures, our technicians inspect the parts, fit hinges, and manually trim them to form a complete frame. Furthermore, our technicians can use one transmission device for both coarse and fine polishing. For this reason, operators only need to swap the polishing wheel to achieve the desired finish. In particular, they can select hemp wheels or cloth wheels for this task.
In this way, staff easily switch between these two polishing modes.
Once frames and temples finish the above respective procedures, our team inspects the parts, fits hinges, and manually trims them to build a complete frame. Subsequently, technicians carry out wet polishing on the entire frame.
Once this final polishing stage finishes, with all polishing steps fully completed, we can now turn to the market demand behind these manufacturing processes.
Overall, eyewear manufacturing has witnessed rapid technical progress. In summary, as a result of these advances, consumers have set higher standards for the precision of glasses polishing products. These are the commonly used processes available today.
Custom sunglasses manufacturers have 13 years of polishing technology research and have been learning and introducing new polishing techniques for many years. Processing technology can efficiently improve the processing efficiency and precision of glasses polishing.
