Slotter Blade For Cardboard Flexo Printer

Slotter Blade

Cardboard slotter blade is a mechanical blade used in cardboard production lines, specifically cutting groove lines on corrugated cardboard so that the cardboard can be folded into the desired three-dimensional shape along the groove lines. This type of cutting tool is usually made of materials such as high-speed steel, manganese steel, or hard alloy to ensure durability and cutting accuracy. ‌

The carton slotter blade is widely used in equipment such as carton printing machines and die-cutting machines, and is one of the key components for achieving carton forming. ‌

The cutting edge of the slotter blade is often designed in a serrated or circular arc shape, forming a U-shaped or trapezoidal groove on the cardboard through rolling cutting, making the folding process smooth and not easily damaged. ‌

The material selection of cutting tools (such as 9SiCr or SKD11 steel) will affect hardness and wear resistance, thereby determining their service life. ‌

In practical applications, the slotter blade needs to be used in conjunction with the lower slotting knife, with a tolerance gap controlled within 0.05mm to ensure the accuracy of the slot position and depth. ‌
