Introduction to the process of sunglasses and glasses

With the rapid development of glasses production technology, the production of glasses sunglasses, is also more and more technical, glasses quality is getting better and better, on the one hand, consumer feedback, with the subjective need for quality improvement, on the other hand, the progress of science and technology, from the comprehensive improvement of glasses materials, processing equipment, testing equipment, management level, objectively to the quality of glasses and sunglasses to provide conditions, the following from the sunglasses frame, sunglasses, glasses packaging assembly and management process several aspects, This is an introduction to the main processing techniques of sunglasses processing.

A.     The frame materials and processing techniques of sunglasses mainly include:

1.                Metal materials: alloy, stainless steel, titanium alloy, B titanium, pure titanium, metal materials using material wire pulling, CNC carving, hydraulic accessories, laser cutting, metal wire cutting, laser welding, manual silver welding, titanium manual welding, polishing and polishing surface treatment, frame shaping, QC testing, electroplating surface treatment, and other processes to complete the production of sunglasses semi-finished frame.

2.                Plastic materials: there are AC, PC, PA, PP, CP, TR, TPE, ABS and other injection molding materials, as well as acetate CP plate, etc., mainly using plastic molds, after high temperature, high speed and high pressure injection cooling molding, the plate is using CNC machine tool machining center or manual auxiliary molding, and then after surface polishing treatment, assembly to complete the manufacture of sunglasses semi-finished frame.

B.      Sunglasses lens materials and processes mainly include:

1.                Resin injection molding CR39, PA NYLON, AC, PC, and other lens materials, mainly using injection molds, after high temperature and high pressure high-speed injection molding, cooling molding, lens curvature in the mold injection molding process is completed, and then cleaned, multi-layer hard coloring and functional film plating, coating is the most important link of sunglasses, and then cut and molded, made into ordinary sunglasses, if attached to the polarizing film will become sunglasses polarized lenses.

2.                Modified press-bending TAC material, using multi-layer AC modified material composite, colored, plus polarized film layer lamination, after the material is cut, the arc is physically bent and formed by high-temperature baking to make sunglasses polarized lenses

3.                Glass lens material, the material is hard, after high temperature processing out of glass blank, and then through spherical grinding and forming arc, and then hardening strengthening, and other anti-ultraviolet, anti-fog, anti-reflection and other functional film treatment, made into sunglasses.

C.     Sunglasses packaging assembly, after the glasses frame, sunglasses are completed, you can assemble the finished sunglasses, mainly using CNC machining sunglasses, LOGO processing is mainly pad printing, silk screen printing, hot stamping, laser engraving, and other processes, plus manual assembly lenses, temples, shaping, QC testing, complete the assembly and molding of finished sunglasses.

D.     In terms of management process, it is mainly affected by the staffing, equipment technical level, workshop environment foundation, and quality management concept of each sunglasses and glasses processing factory, making complete control documents for each link of the process flow, ensuring the basic staffing of production arrangements, process supervision, quality inspection, engineering and technical guidance and other positions, regular personnel training, improving the level of operation technology, strengthening the concept of quality control, specifying reasonable assessment and incentive mechanisms, enhancing employee enthusiasm and encouraging innovation and development. In order to improve the overall management level of the factory, create high-quality sunglasses products.
