In past of a years, many glasses factory including medium factory, are different degree to occurred had Sun mirror "splinter" phenomenon, to factory caused of immeasurable of loss, loss amount less who tens of thousands of, more of do up hundreds of thousands of, into mirror factory complained is lenses quality problem, and Tiffany and Co Key Necklace Jewelry Outlet lenses factory think into mirror factory itself also has problem, what is who of problem, actually does not important has, important of is find causes, for, combines in glasses industry years practitioners experience, on think comparison key of technology for analysis, hopes find problem of crux.
Frames bent is the key
Sunglasses camber usually consists of 600, 800, 1000, Bender bending and bending, most exports of sunglasses were 800, 1000 bending and bending, allowing the larger picture frame making the more difficult. Metal frame forming usually has automatically forming and manually around silk two species, Sun mirror frame forming main is first manual around silk again pressure bent of way, this on on pressure bent mold of precision has demanding, pressure bent mold and by mold manufacturers provides, glasses factory must on pressure bent mold precision repeatedly test, validation its whether meet products production technology, and quality standard of requires, this links to shut important, slightly accidentally, not only will effects products quality, and also will led to "burst tablets" phenomenon. Injection in addition to mold requires high precision, but also closely related to the injection temperature, pressure, time. Plate frames make is like that. Usually, after some changes in curvature eyeglass frames.
Frame welded can not be ignored
Sunglasses not only in terms of curvature than common optical glasses and sunglasses represent a trendy, popular style thousand odd hundred odd, such as Cheap Oakleys Frogskins Sunglasses Outlet, the bottom line is the more popular sunglasses, this class too Tin mirror frames, glasses and other more particular about welding is required. First of all, to make a jig before the welding, horizontal curvature of the fixture to match the frame camber must undergo testing, first to confirm before production, in production, often inspects the quality of products. Secondly, prolonged high temperatures, the jig will be distorted; precision needed to confirm the rear can be used. However, in actual production, because for various reasons, such as busy, ignore the detail control, and ultimately affect the Assembly quality sunglasses or even batch "blast".
Welding quality is not only this, both closely related to surface treatment of metallic glasses, the imprint left by welding, mainly through polishing, polishing can trigger frame deformation, thus affecting the effect of lens Assembly, is caused by a "blast", so during the soldering process, skills requirements to operators, types of welding wire, welding pool must be strictly controlled.
Surface treatment problems
Assembly direct impact on the final quality
Of course, even if the above links are in place, there is no guarantee that does not happen, "stroke" and "explosion" phenomenon, the lens quality is the determining factor. Frames like the body, is the face of the lens without the face, the body would have no meaning in existence, lens sunglasses at its core. Judgement of the quality of the lens, the main performance indicators must be delivered through instruments to detect the results, but does it splinter, current standards are not provided but can be judged by comparing the thickness of the lens surface strengthening layers. If the lens surface strengthened layer is too thick lenses hardness wear-resistant, but less toughness, easy splinter; strengthening layer is too thin, hardness, small easy to wear, but toughness is better, less likely to splinter. In addition, lenses, injection molding of raw materials all affect the quality of the lens.
To sum up, Discount Oakleys Flak Jacket Sunglasses Cheap glasses business only by constantly improving the quality of workers, improve processes, improve internal management, in order to minimize or avoid the "splinter".
