Quality is the most thing that people concerned about in the purchase of any item. Only on the basis of quality compliance, we will compare other aspects. It is the same truth for spring steel strip. However, as spring steel strip manufacturers become more, the quality is gradually uneven. We find that when buying spring steel strip, sometimes its thickness is uneven, but do you know what effect the uneven thickness will bring? Next, I will talk about spring steel strip.
The spring steel strip uses chemicals to oxidize the metal surface to oxides at high temperatures to form a protective layer that is more resistant to rust. Different colors will be produced according to different metal materials, different chemicals, and different construction procedures,. The more common ones are dark blue-black which is very close to black.
First of all, reason for the uneven thickness of the spring steel strip is the raw material is not uniformly melted, which causes the density and hardness to be different. It is easy to produce uneven thickness during the extrusion process. To avoid this environment to appear, time and temperature should be well controlled to ensure that the degree of melting of raw materials is exactly the same in the process of disposing raw materials.
After that, it may also be caused by the machine. The production pressure of the film extruder can not be kept stable. It is probably the presence of foreign matter in the feed port and the discharge port. These reasons cause uneven thickness of the plastic steel strip.
It can be seen that there are more than one reasons for the phenomenon of uneven thickness of spring steel strips. If you want to solve this problem, you must find an accurate corresponding reason. At the same time, it is necessary to pay more attention to these details to prevent the occurrence of uneven thickness of the spring steel strip in the production process.
When you buy spring steel strips on the market and find that uneven thickness, it is not suggested to buy it.Because this kind of spring steel strips will be broken due to excessive force during the application process.
