1. The weaving process is almost the same for security screen mesh machines. If one machine has this kind of problem, then other companies will have the same problem. Even if there is a problem, the mesh master will even adjust it. So the problem here is eliminated.

2. In the process of pulling the mesh, the flat mesh of the security screen mesh uses the two ends of a roll of security screen mesh to be fixed and stretched with a certain strength. When we stretched, one of the corners was loosened and stretched, and one corner was long and the other was short. The situation is commonly known as "angle adjustment". One problem is solved, so why is the mesh surface uneven?

3. In the spraying process, the powder is sprayed on the net surface with static electricity, and then the plastic powder on the surface is baked in the oven, the temperature reaches 200 degrees Celsius. In the process of pulling the mesh, the strength of the pulling mesh should not be too strong or easy to break, not too small or uneven, that is to say, the force applied to it is greater than the yield point of the metal, and it is permanently deformed. After the mesh is flattened, the stress between the internal molecules is still self-adjusting. At this time, the mesh is sprayed into the oven, the metal yield point changes, and the stress is still there, it will return to its previous shape, which is the surface of the security screen mesh. The bend is uneven.

MAISHI has more than 30 years of experience in making security screen mesh. Whether it is drawing or spraying, we will strictly control the time and tension to ensure that the surface of the security screen mesh is flat.
