Automatic zipper threading machine is the name of a kind of equipment for processing zippers. The working principle of the automatic zipper threading machine is equivalent to the process of injecting the plastic in the plasticized molten state (i.e. viscous flow state) into the closed mold cavity with the thrust of the screw (or plunger), and obtaining the plastic products after curing and molding.

Generally speaking, the automatic zipper threading machine rarely breaks down, so when it breaks down, it is necessary to understand the real reason for the failure of the automatic zipper threading machine. On the one hand, it is helpful to quickly handle the failure, and on the other hand, it is of great practical significance to prevent the recurrence of such failure.

There are many reasons for the failure of the automatic zipper threading machine, generally as follows:

1. The design and manufacturing defects of the automatic zipper threading machine itself, as well as the defects in the materials of the parts used to manufacture the automatic zipper threading machine, the internal residual stress, human errors (improper inspection, installation and use), etc., are likely to lead to failures in the production of the automatic zipper threading machine.

2. Bad production environment leads to failure of automatic zipper threading machine, such as dust, temperature, humidity, medium corrosion, vibration, stress state and other influencing factors, which are not conducive to production.

3. Equipment aging and failure caused by too long use of the automatic zipper threading machine, or premature aging of the machine due to inadequate maintenance, affecting the use.

These three points are the common reasons for the failure of the automatic zipper threading machine. Because the failure is very difficult to repair and later production, it is very important to find out the cause of the failure of the automatic zipper threading machine. It is also very necessary to test the technology, and understand that this point can also prevent the failure of the automatic zipper threading machine. It is very important to eliminate the hidden trouble from the root to extend the service life of the equipment.
