Slotting Tools for Packaging Boxes

Jiuheng Precision provides high-quality slotting tools for packaging boxes, designed for carton manufacturing, corrugated board processing, and packaging production lines. Our slotting knives are manufactured with high-strength tool steel and precision grinding technology to achieve accurate cutting, smooth slotting edges, and reliable performance during high-speed production.

Artist's Knives

Made from highly wear-resistant carbide material, these craft knives for everyday cutting offer a service life several times longer and deliver superior cutting quality.

Circular Blades for Slitting Corrugated Cardboard

Jiuheng Precision manufactures high-performance corrugated slitting circular knives designed for high-speed corrugated board production lines. Our slitting knives are engineered to provide precise cutting performance, excellent durability, and stable operation under continuous production conditions. Made from premium tool steels and processed through precision grinding technology, our circular knives ensure clean cutting edges, reduced paper dust, and extended service life.

Are your blades wearing out too quickly and having a short service life?

1. The blade sharpening process takes too long, resulting in wasted sharpening time.
2. The sharpening intervals are too short, and the frequency of sharpening is too high.
3. The air pressure of the sharpener is too high. (In severe cases, this can cause the blade to crack or the grinding wheel to shatter.)
3. The diamond grit size of the grinding wheel is too coarse, resulting in a rough cutting edge and rapid blade wear.

Does the cut cardboard have collapsed edges or rough edges?

1. The blade is not sharp: The cutting edge has not been properly sharpened.
2. The cardboard is too damp, or the cardboard being cut contains a high amount of sand.
3. Insufficient tension on the cardboard: The blade lifts off the cardboard during cutting.

Is the blade cracked?

01. If the blade shatters during sharpening, it is usually caused by a damaged bearing on the grinding wheel shaft, resulting in wheel wobble. Minor wobble can cause notches in the blade’s teeth, while significant wobble can subject the blade to excessive impact forces, causing it to shatter.
2. If a new blade breaks immediately after installation, check the grinding wheel assembly; ensure the blade holder is properly tightened and adjusted; or verify that the air pressure during sharpening is not too high.
3. Excessive cutting resistance can sometimes cause the cut edges of the cardboard to form an S-shaped notch; in severe cases, this can cause the blade to break. For high-grammage cardboard, use thicker blades to ensure sufficient strength.
4. Accidental blade impact: For example, metal foreign objects on the cardboard or foreign objects on the anvil. Sometimes, blade breakage can also occur if the blade holder is not raised when the slitter is reloading blades.

Precision Circular Knives for Slitting Positive and Negative Electrode Sheets

Circular slitting blades for cutting anode and cathode foils used in new energy lithium-ion batteries and 3C digital lithium-ion batteries; the upper and lower blades are designed for use as a pair. They are typically made of high-quality cemented carbide with excellent wear resistance and chipping resistance. Custom blades made of TiCN-based metal ceramics or diamond-like carbon (DLC) coated materials are also available to reduce the occurrence of material adhesion (cold welding) at the blade tip, thereby achieving superior slitting quality and extended service life.

1.High-density cemented carbide material
2.Micron-level precision control of cutting edge defects to reduce burrs.
3.Micron-level flatness machining technology ensures consistent quality.
4.Precision grinding technology for the cutting edge to prevent tool sticking (cold welding).
5.Optional TiCN metal ceramic or diamond-like coating.
