There should be many people who have encountered such a problem. My snap button hit the clothes, but it fell off as long as I pulled it with a little force with my hand. Maybe you think it's a bad joke, how could it be?
As long as the A+B+C+D side of the snap button is hit on the clothes with a mold, as long as the general clothes are not particularly thick, they will not fall off at all. On the basis of the lack of quality of the product, one possibility of falling off can only be caused by the mold. One is that when the mold rivets the A side and the B side, the pipe on the A side is not flattened and rolled. On both sides of the surface, it is directly crooked; the second reason may be that the C surface and the D surface are not pressed tightly when the mold is riveted. When this happens, in the final analysis, it is the quality of the product itself. In the end, the quality of the product itself has to be improved, and there is less.
Why does it mean that the quality of the product will determine the good results, but will reduce it? One is to improve the material of the product, thicken the material of the product, and at the same time increase the pressure and impulse. The second is a harmonious design in the product structure. As far as possible, it is suitable for general die riveting. In addition to the possible occurrences listed above, it also has a certain relationship with the machine that makes the snap button. In the process of using the machine all the year round, there will be more and less wear and tear, and when the four-in-one button is pressed, the direction will move, and the force will be uneven on the mold. This will also affect the riveting of the snap button.
