I have been working in the global eyeglass manufacturing industry Bart Starr Jersey , supplying raw materials, parts and accessories to distributors and manufacturers around the world, since 1999. When I first began, there were manufacturer pockets around the globe in various countries. As time went by, like many industries David Bakhtiari Jersey , the demand for cheaper products consistently bore weight on the drive to decrease cost, which led to manufacturing in China. The economies of scale as well as the very low cost of manual labor helped to drive the exodus to China. Difficult products are still being manufactured in small clusters around the world, however the "meat and potatoes", the "grunt work" has moved offshore to China.


Titanium (pure or alloyed) wire and sheet is the preferred material to make frames of these days. The unit cost is very expensive compared to ferrous metals, however the properties are far superior. It is much more difficult to work than regular metals during the 200 step process to make a pair of frames. Because of this Dexter Williams Jersey , technology was often limited to countries like Germany and Japan who invested a long time ago in developing processes to work this material. Japan has been selling a lot of its technology to China in the past decade so that now, standard titanium eyewear is usually made in China at a lower cost than Japan which has led to a lot of "restructuring" in the Japanese optical industry. Those companies that have a competitive advantage have survived (i.e. a specialty), however the "plane Jane Vanilla" types are, to a great degree, gone.


People do not know this but it takes approximately 3 months and 200 steps to make a pair of eyeglasses. There is a huge amount of outsourcing done to specialists who do various parts of the process. The titanium used in eyeglass manufacturing must have a very good surface quality. Because titanium is so hard (and yet so soft at the same time) Jace Sternberger Jersey , it is easy to make deep scratches, but very difficult to polish it out. Here, not I did not say "grinding" because grinding connotes "making smaller", but instead use the term "polishing" which results in a smoother, shinier surface with less blemishes. The end result is different Elgton Jenkins Jersey , therefore the terminology is different.


Because removing scratches from titanium is difficult, the manufacturers demand the highest surface quality. Eyeglasses are a fashion, they are painted, plated or coated and then worn on the face. When you meet someone the first thing you see is their eyes, and if they are wearing glasses you see those. Because of this Darnell Savage Jr. Jersey , the finished surface needs to be as blemish-free as possible. Without a smooth surface, the paintplating will not apply evenly and you will end up with defective product that will not be purchased by the wholesalers and distributors to put on the market. In reality, most end-users may not even notice the level of perfection that the wholesalers are demanding. After all, how do you choose a pair of glasses? You find a color and shape you like, put them on your face Rashan Gary Jersey , look in a mirror to see if they suit your image of yourself, then scan your friendfamily memberstore clerk's face and response to see if their impression of the frames on your face seem suitable to them. If so, you buy. If not, you keep looking. Most of the scratches and blemishes that the manufacturers are required to prevent would not be noticed by the end user, quite possibly allowing manufacturers to decrease their defective count allow them to purchase lower-priced material and maybe make glasses even cheaper; however the companies that order the frames go far beyond that in detail.


Because of this Packers Kids Jersey , the manufacturers must have the best material available. This means a very high price compared to other titanium used in non-eyewear industries. There is a constant drive to find a lower priced titanium material for eyeglass manufacturing, but to date, the only material suitable is that which is made by the Japanese. I have tried supplying US material, Russian and Chinese but all fail for their various reasons. The U.S. material surface is not up to quality because it is used mainly for "rougher" industrial purposes. The Chinese and Russian is still unstable in terms of content.


The manufacturers also demand tight tolerances in the material diameter or thickness. Usually tolerances for titanium in the optical industry are +- 0.02 or 0.0.3 mm.


We have two levels of quality for titanium sheet here in Japan. One is like a "mirror finish". Obviously it doesn't reflect like a mirror, but it is smooth. This is what the manufacturers need. The other one looks like someone slathered a thin layer of epoxy on the surface and then sprinkled sand over it. This CANNOT be used to make eyeglasses.


For titanium sheet Packers Youth Jersey , usually anything under 3 mm thickness by Kobe, Sumitomo, Shin Nittetsu are usable as is. For thicker sizes, the surface gets too rough and we have to use a cold rolled sheet. This meaning I would order 4 mm, my supplier would have his supplier roll 5 mm down to 4 mm so the surface was smooth. Again Packers Womens Jersey , this process drives the price up on titanium that has already been increasing dramatically in the past year.


Eyeglass factories are "small" compared to other industrial processing plants. The machines are small, hand operated, and so forth. The size of the sheets that feed into the machines are limited. This means that standard sheets (usually 1m x 2m) need to be cut into about four pieces in order to be used by most manufacturers.


The manufacturers of the titanium will not cut the standard sizes sheets, however the wholesalers who buy bulk and stock in Japan will. They know this is necessary for the industry. I have yet to find a company outside of Japan that is willing to do this; making the sale of sheet extremely difficult to the optical industry from non-Japanese sources.


My advice to suppliers outside Japan is this: This process may be different from what you
