Corrugated industry fan blade
Corrugated fan blade

Fan-shaped knives are also called slotting knives. As the name suggests, they are generally used for grooving of carton boxes and paper towels. Fan-shaped knives are divided into toothed and non-toothed, which can easily make one or more grooves on corrugated cardboard. Usually use Cr12mov or 9Crsi material.

The production line of the corrugated paper industry refers to the key production equipment in the production process of corrugated paper. The required equipment and production process depend on the scale of production and the degree of automation. In the corrugated paper industry, a process that corrugated boxes must go through is slotting. Grooving knives are often used in the industry.
Slotting process of fan blade

After grooving with a fan-shaped knife, certain indentations are created on the cardboard. The main function of these indentation lines is to make the corrugated cardboard accurately bend according to the predetermined position to achieve the inner size of the carton.
Blade material of fan blade

The blade materials most commonly used in the machinery knife industry are roughly divided into four types: cemented carbide (TC), high speed steel (HSS), Cr12mov (D2, also known as SKD11), and 9CrSi. In general, the choice of common blade materials has its industry conventions. For example, large round knives are suitable for Cr12mov material, and fan-shaped knives (also called slotted knives) are suitable for 9CrSi and D2 materials. Small round knives are most commonly used for high-speed steel materials, but D2 and 9CrSi materials are also used a lot. These corresponding suitable materials are the most cost-effective while maintaining good use results.
