Classification and opinions of metal zipper

Zipper is a big family, each a product due to the evolution of the chain teeth, tape and pull head shape, texture, pattern, color, and so on many small branches, thus making zipper varieties is rich and colorful. How to reasonable classification, which is convenient for the user, standing in different angles using the classification method is not the same, at present, the classification of the zipper in the world has more than a dozen of, each have each characteristic, it is difficult to say what kind of classification method is better, new metal zipper standard according to the characteristics of the metal zipper for the two categories: one is according to the type of the zipper, and the second is according to type of the zipper.
 
According to the type of zipper is divided into strip and code. Full zipper is divided into open style and closed tail type zipper zipper. Cotter type zipper can be divided into single open-end zipper and double zipper tail; closed tailed zipper can be divided into single head close end zipper and double close end zipper; double close end zipper can also divided into "0" type close end zipper and the "X" close end zipper.
 
Packing is in long chain state individually packaged and sold it with the same specifications of the pull head. New metal zipper standard, listed the main zipper models: numher 3, 4, 5, 7, 8, 10..
 
Zipper formation has many dimensions, it is with a combination of a dimension chain and the size of each, as the industry generally recognize that the chain teeth meshing width of zipper model corresponding to. It is often said that a certain size is few number, such as chain teeth meshing width is 6.5mm, said 7 zipper. But from the international standard classification of the main zipper production country, this understanding is not uniform, some countries according to the bearing capacity of the zipper, divided into light, ultra light, medium, heavy, overweight, and even some national standard classification is by size and type of echoes, but only this chain meshing width for a selected range of values, and not a specific value, the benefits of doing so is to the zipper manufacturers of products has brought a certain size choice space, but also makes the enterprise in the actual operation or production process has also brought a certain degree of difficulty, that is to say, there may be different manufacturers out of the zipper, although the model is the same, but not necessarily be able to pull the head to match with the chain belt, it causes confusion and inconvenience to the consumer.
 
About how to choose a model representative of the size, in the industry has been controversial, some people believe that with the development of production automation and information, the zipper dimensions must be strict and uniform, so as to realize standardized production, chain and parts in order to realize universal and general, this can reduce material consumption, improve the quality of the products, also can realize the industrial chain division of labor. People who hold different views think, if the zipper model for a specific size, it will bring a lot of business risk, but also not conducive to the production of personalized products.
