This process hardens the metal, making it extremely strong. Advanced laser or high-precision mechanical cutters slice the strip into shapes, often with a slight curve to match the contour of a safety razor or cartridge head.
Automated Razor Blade Production: From Steel Strip to Heat Treatment and Packaging
The shaped blades are heated to a specific temperature in a controlled furnace, then rapidly cooled, or quenched, in oil or water. Immediately after quenching, the blades undergo tempering, where they are reheated to a lower temperature and then cooled slowly.
They are typically sealed in protective sleeves or strips made of plastic and paper, which shield the cutting edge from damage and contamination until the moment a consumer uses them. Core Material Selection and Preparation The foundation of every high-quality razor blade is the steel alloy itself.

Initial Rolling and Strip Formation The cleaned steel coil is fed into a series of heavy-duty rolling mills. Heat Treatment and Tempering Heat treatment is the most critical step in transforming soft steel into a resilient, sharp edge.
