What Are The Pretreatment Methods For Extruded Stainless Steel Cable Ties?

I believe many of you have seen Stainless Steel Cable Tie in your daily life. It has a wide range of uses, but do you know its production process? Manufacturers often need to go through several processes to complete the entire production of cable ties during production. Today, we will talk about its pretreatment technology, and there are two common pretreatment methods.
There are two pretreatment methods for extruded stainless steel cable ties: alkali immersion method and shot peening method.
1. Alkaline leaching method
This processing method involves soaking the material in alkaline molten salt or solution, and the structure of the oxide skin will change. There are two methods of alkali leaching, namely molten salt alkali leaching and solution alkali leaching. After being immersed in molten salt alkali, the surface of the material will not be affected. During acid washing, metal loss will be much less, and the acid washing time can be shortened, effectively improving production efficiency.
However, it should be noted that the temperature of molten salt needs to be maintained at a high level, so its energy consumption will be relatively high. The method of salt alkali leaching requires the establishment of a specialized alkali tank, which has a long heating cycle and high energy requirements. Therefore, many low yield products commonly choose the relatively low-cost solution alkali leaching process. The solution uses an alkaline potassium permanganate aqueous solution.
2. Shot peening method
The shot blasting method uses a polishing machine to accelerate the pellets, and after accelerating for a period of time, they are sprayed at a fixed angle onto the rotating surface of the material. Due to the impact of the pellets, the surface of the material will undergo elastic deformation, and the oxide scale will break and fall off after the impact. This method is more suitable for materials with certain hardness and resistance to fragmentation, and the material, speed, and amount of pellets will all affect the pre-treatment effect.
That's all for the pre-treatment method of extruded stainless steel cable ties. I hope you can master this knowledge after reading it.
