The manufacturing process of a safety razor blade involves die stamping carbide steel and welding the blades to a steel support member. Plastic components are extruded or injected molded and then readied for assembly. The assembly process begins with the assembly of the blade cartridge and plastic ports. The molded plastic components are held in place with vacuum lines as the spring loaded arms push the blades into their slots. The finished cartridge may be attached to the handle during subsequent operations or packaged separately.
During the manufacturing process, the plastic components are molded simultaneously with the blade. Once complete, these parts are prepared for assembly. The plastic resins are mixed with colorants, stabilizers, and fillers. After mixing, the powder is heated in a specially designed screw feeder to melt it to a fine powder. Once cooled, the pellets are shaped. The blades are then assembled. To reduce waste, many people opt for a plastic razor with a disposable blade.
Stainless steel used for razor blades was first made in 1895 by King Camp Gillette. The invention had a separate handle and clamp unit that allowed for blade replacement when it became dull. The paper-thin blades were created with two-year-old metal working technology. In 1901, King Camp Gillette patented the disposable razor and sold 51 razors. A year later, his company sold two million disposable razors. The technology used to create these disposable blades was developed to allow for a continuous production cycle.
Stainless steel is used in the manufacture of safety razors. Jindal Stainless is one of the world’s largest manufacturers of this material. Some manufacturers use the same steel for razors. Another option is to purchase a safety shaving device that includes lubricating strips. These strips are made of acrylic polymers and mounted on the head of the razor. The water helps the blade glide across the face. This method helps the user maintain a safe skin and prevents irritation.
Stainless steel is used to produce safety razors. The main reason for this is the increased safety of the safety razor. In the early 1800s, the hoe-shaped safety shaver was manufactured in the United States. It had a steel blade with a guard along one edge. King Camp Gillette combined the hoe shape with a double-edged replaceable blade. By the mid-1960s, several countries began producing stainless steel blades for a variety of types of safety razors.
Other types of safety razors are lubricating. They contain a thin layer of lubricant on the blade, which helps the blade glide smoothly over the face. Some of these devices also have a lubricating strip on the head to help a user shave with the safety razor. These strips also help the blade glide easily across the face. Besides the lubricating properties, these plastic strips also help the safety of the safety razor.
