The zipper machine is the name of a kind of equipment for processing zippers. The working principle of the zipper machine is equivalent to using the thrust of a screw (or plunger) to inject the plasticized molten state (that is, the viscous state) into the closed plastic. In the mold cavity, the process of obtaining plastic products after curing and shaping.

Generally speaking, zipper machinery rarely fails, so when it fails, it is necessary to understand the real cause of the zipper machinery failure. First, it will help to quickly deal with the failure, and secondly, it can also prevent this. The reoccurrence of such failures has important practical significance.

There are many reasons for the failure of zipper machinery, generally as follows:

1. The design and manufacturing defects of the zipper machinery itself, as well as the defects of the parts and materials used in the manufacture of the zipper machinery, internal residual stress, human errors (inspection, installation and improper use), etc., all of which can easily lead to the failure of the zipper machinery in production .

2. The bad production environment causes the zipper machinery to malfunction, such as dust, temperature, humidity, medium corrosion, vibration, stress state and other influencing factors, which are not conducive to production.

3. If the zipper machinery is used for a long time, the equipment is aging and malfunctions, or the maintenance is not done properly, which leads to the early aging of the machinery, which affects the use.

These three points are the more common reasons for the failure of zipper machinery. Because the failure is not conducive to maintenance and later production, it is very technical and necessary to find out the cause of the failure of the zipper machinery, and it is also necessary to understand this point. It can also prevent the zipper machinery from malfunctioning, and it is very important to prevent the hidden danger of the malfunction from the root cause to prolong the service life of the equipment.
