Production Method

Only modern mechanical equipment can be used to make the zipper. But the core elements that make up the zipper are the oldest and simplest tools in the history of human civilization: wedges and hooks.

A wedge is nothing more than an object with a bevel. If you push an object forward with a wedge, you push the object to the left or right. In other words, the direction of the force applied by the wedge to the object is always perpendicular to the direction of motion of the wedge. A door bump is a good example of applying this principle: when you push the door bump under the door, it exerts an upward force on the bottom of the door. The plow is another common wedge - it pushes dirt or snow to both sides as you push it forward.

The hook is of course a curved material that can be used to catch another piece of material. For thousands of years, hooks have been used as a fastening device because it is simple and usually very strong. When used as a fastening device, the hook is generally used in conjunction with something that is ring-shaped, eye-catching or has a hole in which the hook is to be hooked.

Maintenance skills

1. When using it normally, pay attention to whether there are any problems such as “broken belly”, “de-toothing” and skewing on the zipper. If you have these problems, repair them in time and do not pull them hard. If the zipper is loose and toothed, use a small hammer to gently tap the zipper head a few times to make the upper and lower chain teeth bite tightly, and then no more teeth.

2, the zipper of aluminum alloy is more susceptible to corrosion, so it should be kept dry, do not get damp, to prevent the aluminum tooth from forming white oxide, it will lead to rust and rust over time, affecting the use, but also pay attention to not alkaline Contact with acidic substances. Keep a certain degree of ventilation during storage, do not seal it, do not store it in a humid atmosphere, or use moisture-proof paper or dehumidifier if necessary. If the zipper is damp and pulls up, then the zipper will be sun-dried, then some wax will be applied to the zippered teeth, and then fired, so that it is very lubricated.

3. When pulling the zipper, first align the teeth on both sides, then pinch the zipper head and gently pull forward along the track. Do not forcefully pull it to avoid “tooth skew”, “broken belly” and “toothing”. . If the zipper is bun and the pull is not flexible, you can wipe it with a cloth and then apply a layer of white wax on the “teeth”.

4, a variety of bags, pockets or wallets with zippers, do not overfill, otherwise it is easy to make the zipper caused by "breaking belly", "toothing", skew and cloth soft.
