< p > 1. The classification of fasteners is < /p >.

< p > fastener is generally divided into insert button series (also called side button), buckle series, rope buckle series, rubber foot series, garment auxiliary material series, five < /p >

< p > Gold fastener series, pull rod series, tag series and so on.

Among them, buttons, hooks, rope buckles, rubber feet, < a href= "http://www.91se91.com/news/index_c.asp" > shoulder pad < /a > hardware are commonly used to us.

< /p >

< p > two, all kinds of fastener materials, characteristics, uses and other < /p >.

< p > 1, socket < /p >

< p > the materials selected are generally POM (POM, commonly known as Sai Kong), PA and PC < /p >

< p > the buckle is composed of a male button and a female button. The ends are stitched respectively, and the length of the webbing is selected according to different needs, generally used for shoulder and < /p >.

< p > waist fixation.

In order to more effectively play the role of button, there are more convenient and scientific plugging, such as the replacement of invisible parent < /p >.

< p > button.

This is a button that can be easily replaced without stitching the ribbon.

The other is the three direction buckle, that is, the "Y" button. It is commonly used in the baby carriage "/p".

< p > on the whole product, the female buttons can be designed according to the customer's design and authorization, or the choice of plating, silk screen and coloured drawing can also be made by LOGO.

< /p >

< p > 2, < a href= "http://www.91se91.com/news/index_c.asp" > hook < /a > /p >

< p > its materials are generally POM, PA and PP < /p >.

< p > generally speaking, collage, D buckle, buckle, day buckle, square buckle and ladder buckle are collectively referred to as hooks. They are usually used for hook and D buckle, while Japanese characters are up to /p.

< p > to adjust the length of the webbing, the ladder buckles are usually used on the ends of the webbing, which play a major role in fixing. The buckle can be plated and printed, usually in ladder < /p >.

< p > button can be designed LOGO.

< /p >

< p > 3, rope buckle < /p >.

< p > its materials are generally PA, PP, PC, POM < /p >

< p > rope hole optional caliber, single hole and double hole, suitable for all kinds of OO rope, nylon rope, elastic rope.

And we can design < /p > according to the requirements of customers.

< p > LOGO < /p >

< p > 4, glue foot < /p >.

< p > its material generally comes from PVC < /p >.

< p > the glue foot is divided into granular and strip. It is used in the bottom of the bag or box to effectively protect the goods from abrasion. It is an indispensable material for the box, and < /p >.

< p > and has the function of skid resistance. It protects the articles from damage under special circumstances.

< /p >

< p > 5, shoulder pad < /p >.

< p > material is PVC, PU, TRP, TPE < /p >

< p > > a href= "http://www.91se91.com" > shoulder pad < /a > has the function of slowing down the pressure and positioning the skid resistance. The front side of the shoulder pad is called the back, and the reverse side is called the abdomen < /p >.

< p > handlebars are the most commonly used parts of people. The ribbon is inserted into the handle to make the interior firm and not easy to move, so that it can be arbitrarily coloring and can be set up < /p >.

< p > LOGO < /p >

< p > 6, hardware < /p >.

< p > material is generally POM < /p >

< p > divided into hardware buckle, day button, square button, key chain, chain, < a href= "http://www.91se91.com" > zipper head < /a >.

< p > four, the test of the fastener is < /p >.

< p > fastener has two main aspects in the testing process: < /p >

< p > one is the pull test, which is mainly used to detect the bearing capacity of fasteners. It is divided into two steps: < /p >

< p > 1, tensile test, mainly used for buckle, D buckle, day button and so on; < /p >

< p > 2, lasting tension test, its main principle is to determine the time value of fastener when determining a certain load.

< /p >

< p > the second is the temperature test. This is mainly to test the bearing capacity of the fastener under unconventional temperature. It is divided into two types: high temperature and low temperature < /p >.

< p > 1, high temperature is usually set at 70 degrees Celsius < /p >.

< p > 2, low temperature is usually set at minus 30 degrees < /p >.

< p > time is 24 hours, and the corresponding values can be detected according to different needs. Among them, the metal fastener is also less than /p.
