A good umbrella is divided into three parts: ribs, umbrellas, and springs and umbrellas, mainly different technologies. The Germans used conventional car manufacturing technology, and the Japanese used the stamping process. At present, China is still mainly stamping, and it is more suitable for mass production at low prices. The strength of the car manufacturing process is much greater than that of stamping. Japan has hand-made umbrellas and hand-made umbrellas. It is also a car-made one. The price is not expensive, between 500-1000.
On the surface of the umbrella, it is generally coated nylon, and mid-range has TDF material, which is similar to that of outdoor clothes, but it is not the same.
The top is hand-woven, usually a luxury, not waterproof. If you can do it, UK REDTUBE has this process,
The galvanized spring is the most important. China is currently unable to independently produce umbrella springs, which are generally imported from Japan. Japan is imitation of Switzerland.
Switzerland is doing this top class. A good umbrella spring needs 3 technicians to do it at the same time for 4 hours. There are hand-carved inscriptions inside each part, even though maybe no one will think of it for a hundred years. Look inside.
It is true that an umbrella can be used for more than a hundred years. Everyone can pay attention to the same thing. When the British royal family celebrated, the umbrella of Queen Elizabeth was taken when she was in the throne.
