Stainless steel nail files are widely used by people to shape and smooth their nails. They are long-lasting and durable, and they can also be sterilized for hygienic purposes. Have you ever wondered how these nail files are made? In this blog, we will take a closer look at the manufacturing process of stainless steel nail files.
1. Material Selection
The first step in making a stainless steel nail file is to select the appropriate type of stainless steel. The most commonly used stainless steel is the 410 grade because it is hard enough to create a good edge and does not corrode easily. The stainless steel sheet is then cut into small strips of the required size.
The strips of stainless steel are then fed into a milling machine, where they are ground to the desired shape and length. The milling machines use diamond-studded wheels to create the rough shape of the nail file.
Once the rough shape of the nail file is created, the next step is to etch the surface of the file. Etching is performed using an acid solution that removes any rough spots or marks on the surface of the file.
4. Heat Treatment
After the etching process is completed, the nail file is heated to a high temperature for several hours. This process is known as annealing and it helps to reduce the brittleness of the file.
The final step in the manufacturing process is grinding. The nail file is placed on a grinding wheel and is ground to smooth out any rough edges or bumps. The grinding process creates a fine edge that is sharp enough to file nails but not so sharp that it will damage the nail.
Stainless steel nail files are made by selecting the right type of stainless steel, milling the steel to the required shape, etching the surface to remove any imperfections, annealing to reduce brittleness and finally grinding to create a sharp edge. The manufacturing process guarantees that the nail files are of high quality, long-lasting and safe for use.
