Why Does The Sunglasses Appear Lobes?

Why does the Sunglasses appear lobes?
Many Sunglasses factory, including large and medium-sized factories, are varying degrees of Sunglasses "lobes" phenomenon, to the factory caused by immeasurable losses, the loss of tens of thousands of less, more than a few hundred thousand dollars, Lens quality problems, and the lens factory that the mirror itself has a problem, who is the problem, in fact, is not important, it is important to find out the reasons for this, the author combined in the Sunglasses industry for many years experience, The process of analysis, hoping to find the crux of the problem. Frame bending is the key Sunglasses curvature is usually 600 bend, 800 bend, 1000 bend, export Sunglasses to 800 bend, 1000 bending majority, the greater the curvature, the greater the difficulty of making the frame. Metal frame molding is usually automatic molding and manual winding wire two, Sunglasses frame molding is mainly the first hand-wound wire and then bending the way, which is bending the accuracy of the mold has strict requirements, bending mold by the mold manufacturers to provide, Sunglasses factory must bend the mold precision test repeatedly to verify whether it meets the product production process, Sunglasses manufacturer quality standards, this link is important, a little careless, not only will affect the quality of products, but also lead to " Burst "phenomenon. Injection molding frame in addition to the precision of the mold demanding, but also with the injection temperature, pressure, time is closely related.
Plate frame frame production is also true. Usually, after the molding of the Sunglasses frame will be part of the curvature has changed. Frame welding can not be ignored, polarizing Sunglasses manufacturers said that not only in the curvature than ordinary optical Sunglasses, and Sunglasses on behalf of the fashion, fashion, style strange, such as Ray Ban, on the line and so are more popular Sunglasses, such Sunglasses on the frame, glass and other welding requirements are more stress. First of all, in the welding before the production of mold fixture, cross-clamp with the curvature of the frame coincide with the frame must be tested, the first piece of confirmation before the production, in production, often patrol product quality. Second, the mold fixture in a long time under the high temperature will be distorted, precision need to be confirmed later can be used. However, in the actual production, because the production busy and other reasons, ignoring the details of control, and ultimately affect the quality of Sunglasses assembly, and even lead to batch "burst film" phenomenon.
Welding quality is not only in this, but also with the surface treatment of metal Sunglasses are also closely related to the printing left by the printing is mainly through the polishing process, and polishing easily lead to deformation of the frame, which affects the lens assembly effect, is " So in the welding process, the operator's skill requirements, wire type, welding time and so must be strictly controlled. Surface treatment problems A lot of Sunglasses surface treatment methods are mainly polished and drums, manual polishing is still very common treatment. Before polishing, should be for different materials, select the appropriate polishing disc, for example, the layout of ordinary copper (Kam) alloy disk, stainless steel disk, titanium Taiwan special disk, and so on.
The specifications of the polishing disc should also be determined, for example, in the handling of the inside of the pile head marks or pits, you need a small size polishing disc. If the objective factors such as polishing discs, machines and other factors affect the quality of the product, then the role of people is immeasurable; operator skill proficiency directly affect the quality of products, most of the Sunglasses frame after polishing will appear straight Phenomenon, the metal frame will be hardened after plating, is bound to affect the difficulty of loading film, the lens in the frame on the force, over time there will be "cat to be", "burst" and so on. Moreover, now people mobility, skilled workers uneven, coupled with the production of busy, so in this part is also the most prone to problems.
Cut the chip is also the key quality control point cutting speed is not too fast, too fast will not only accelerate the blade wear, and cut out the lens rugged, jagged, in the stress lamp irradiation, will find cracks around, After a long period of time in the external force will be lobes. This is true for lens perforation and slotting. If the above process can control the effective, then the impact of the quality of the lens is assembled; for the body of a single frame, the film is very simple, but for the large curvature, complex shape of the frame, there are a lot of film Little trick. For example, for frameless, upper and lower Sunglasses and other Sunglasses, completely rely on a few screws to the lens fixed to the frame, the film, the lens must be burr removed, put in the mirror hole before and after the gasket, Sets of screws into the mirror hole, with the screw to the lens does not loose so far, but the manual operation can not control the force is appropriate, in order to prevent the resulting adverse consequences, it is recommended that manufacturers recommend the use of electric screw screw machine instead of artificial operations The Otherwise, for ordinary acrylic, PC lens, there will be "cat to be" phenomenon.
