Zirconia Ceramic Blades have the characteristics of high hardness, excellent sharpness, no burrs, low friction coefficient, clean cutting edges, corrosion resistance. On the production line, zirconium oxide blades can not only improve the quality of work, but also improve work efficiency.
In the entire industrial process, cutting is a very important process, and in this process, the blades used are generally steel blades, but steel blades have big defects when they are used. In contrast, what are the advantages of ceramic blades made of zirconia?
First of all, ceramic blades can reduce resistance when used. We know that in some cutting processes, some blades have a certain amount of application when used, but they are not suitable for use because of large resistance, and the resistance will cause the object to be cut. The pulling force is prone to burrs or other undesirable phenomena,
Zirconium dioxide blades are not suitable for cutting thicker and harder materials. However, when zirconia blades are applied to cut thin and soft materials, for example, tape, aluminum film, paper, leather, yarn, nylon wire, fruit, vegetables and meat. They not only have good self-pressure, but also can rotate smoothly. The purpose is not only to achieve good results in cutting, but also to be more suitable for multi-layer cutting, which is also an effect that other blades cannot achieve.
Because of the obvious advantages of zirconia ZrO2 blades, they play a very important role in various cutting operations. Of course, according to the field of application of blades, there are many types of zirconia based ceramic blades, such as Utility Blade, Xacto Scalpel Blades, Trapezoid Blade, Safety Blade, Razor Blades, Capsule Cutting Blade and so on.

Manufacturing Introduction
Ceramic blades are constructed of ultra-fine zirconia ceramic powder that is sprayed, granulated, and ball milled before being pressed into shape using dry pressing, cod isostatic pressing, or tape casting, depending on the case, and then sintered at a high temperature of 1,600 degrees Celsius to form a lightweight and hard material. Finally, diamond grinding wheels are used to carve, drill, polish, and sharpen the blades, depending on their form and precision specifications.
