Frame Manufacturing

Such frames without frame no lens ring, only the metal nose and metal temples, lenses and nose bridge and temples are directly connected by a screw fastening, generally on the lenses punch. No frame more compact than ordinary frames, chic, but somewhat less intensity. Combination frame at the front frame has two sets of lenses, one group can be turned, usually indoor and outdoor dual use. Folding rack frame can be folded to four fold or 60%, mostly for reading mirror. Excellent corrosion resistance, which would then not easy to change old frames, and frames can protect against chemical erosion. Mainly composed of parts processing, assembly, polishing and surface treatment processes four components. A spectacle frame usually two, thirty kinds of <a href="/blog/blog_error.asp?mode=20">Cheap Oakleys Frogskins Sunglasses Sale parts, the main mirror circle, temples, nose pads, hinges, locking block and screws and so on. Parts material properties and dimensional accuracy directly determines the process after the procedure and final product quality, and thus part machining process is essential. Metallic material constituting the optical part by material selection key indicator is based on the merits, namely: mechanical properties, process, corrosion resistance, wear resistance, plating resistance, color and so on. The continuous development of metallic materials glasses are designed around the performance of the above research, improve to be achieved.
Metal frames are generally manufactured as a metal substrate and its surface treatment; surface treatment method is basically known as gilding with gold that is wrapped in gold alloy substrate sheet. Representation of gold in two ways, first open the package weight of gold frames accounted for the proportion by weight of pure gold frames with a weight ratio of representation. Gold plated, for example, in other metal plating on the frame material, titanium, black chrome plating and so on. To improve the appearance, but it has gold corrosion resistant characteristics. Gold plated and gold colors with which to open the type of metal on the other, more whitish zinc, copper and more wish. Coloring known <a href="/blog/blog_error.asp?mode=20">Tiffany and Co Bracelet Jewelry Outlet coating is applied by spraying the surface of the frame of the substrate processing. Such as epoxy powder coating, plastic coating coloring and so on. This method not only can be rich in color, but also for multi color processing.
In the plastic sheet on the frame and temples cut out, put together by a hinge. This processing method is good quality, but the high cost, for less mass. Injection molding, the plastic softens, vacuum casting into the mold. The so called frame of reference line is through the inner edge of the frame around the two highest and <a href="/blog/blog_error.asp?mode=20">Cheap North Face Denali Jackets Sale lowest points parallel to the tangent bisector. All measurements are vertical direction starting from the baseline. Mirror lens ring size is between the temporal and nasal baseline length, nose width is two recent baselines and the distance between the lens ring intersections. Glasses frame glasses frame a mirror of the foot marked size, model and color, while the other mirror foot is marked origin, manufacturer name, and frame materials. Box frame has been measured for the International Organization for Standardization and recognized by all its members. As the name implies, is painted with the lens box method tangent circumscribed rectangle, for the corresponding frame is concerned, this is also circumscribed rectangle tangent to the inner tank and the frame. The width of the box is equal to the width of the ring mirror frame, is also equal to the width of the lens referred to.
