Remove the leftovers. So what is the production process of screws? What are the processes and precautions? Let’s follow the stainless steel screw factory to have a look. Introduction of screw manufacturing process In the screw manufacturing process, the actual requirements for pickling are particularly strict. Wholesale Self Tapping Screws Manufacturers. To control the concentration and temperature in the pool, under this premise, pour the pan into the pool that we have prepared.
The first step is to remove the oxide film on the metal surface. For screw manufacturers, pickling is a transitional period in the production of stainless steel screws. Such mastery requires the operator to have a good grasp of the time, and it is also conducive to the realization of methods to prevent corrosion of stainless steel screws, otherwise pickling It’s just a cutscene, which has no practical meaning, and affects the actual operation in the later stage.
Oxalic acid is to increase the activity of metals and lay the foundation for the next moral coating. Change the pool, the step here is called clean water, the main function is to remove corrosive substances on the surface. Here, the screw manufacturer reminds everyone Don’t underestimate this film, the role of this film in the later spraying or molding process is also relevant and important. Second, the role of pickling in screw production
As a key step in the pickling treatment, the phosphate should contact the surface of the metal material to form a film.Screws are widely used in modern industry and life, and the functions of different types of screws are quite different.
In order to remove the oxide film on the metal material, and to remove the oxide film, a phosphate film should be formed on the surface of the metal. Such steps seem simple, but we must grasp the time well during operation. For the use of screws, we generally choose and use them according to actual needs. Such a step must be implemented well in order to complete our following processes to ensure that stainless steel screws meet certain quality requirements
