About the production process of acetate eyewear
Following is a brief introduction about our acetate eyewear producing process.
Usually, eyewear include acetate eyewear, metal eyewear, titanium eyewear, aluminium eyewear and carbon fiber eyewear, etc. And eyewear must be manufactured with great attention to detail because they are critical in supporting lenses to improve vision, they must be comfortable for the wearer, and they are an accessory to professional dress and personal style. Although processes for making frames are performed by machines, operators are responsible for each step and are quality control checkers for their particular operations. The eyewear industry has become highly competitive because of the aspects of fad and fashion involved, but operators are well aware that their products provide vision care. Fronts and temples for eyewear can be rejected at any step in the process of manufacture.
