Multi Bottom Knives integrate multiple cutting knives into a single knife body for efficient and consistent multi-lane slitting. Available in single-edge or double-edge configurations, they can be supplied with different locking systems to suit various machine designs.
Standard knife spacing of 5 mm or 10 mm provides consistent slit widths while the integrated design simplifies installation. Compared with individual bottom knives, Multi Bottom Knives offer a compact structure, faster setup, consistent knife spacing, and lower overall system cost.
These knives are designed for slitting machines, rewinders, and converting equipment and are suitable for paper, paperboard, plastic films, labels, adhesive tapes, flexible composites, nonwoven materials, thin paper, and textiles.
Mounted on the bottom knife shaft, Multi Bottom Knives work with upper dished knives, flat knives, knife holders, or pneumatic knife holders to form a complete shear slitting system. WINGCHONG KNIFE can also manufacture matching knife and holder components for precise system compatibility.

Grooved Sleeves are precision-manufactured components designed for slitting machines, knife assemblies, shaft systems, and web converting equipment. They help provide accurate positioning, stable installation, and reliable spacing between slitting components.
As a custom grooved sleeve manufacturer, WINGCHONG KNIFE manufactures sleeves according to your machine configuration, shaft dimensions, groove requirements, and application conditions. Custom outside diameter, inside diameter, length, groove dimensions, tolerances, and materials are available to ensure a precise fit with your existing slitting system.
Simply provide your drawing, sample, or technical specifications, and our engineering team can recommend and manufacture the appropriate grooved sleeve solution.

30° Crush Cutting Knives are precision slitting knives designed for rewinders, flexographic printing machines, inspection equipment, and slitting machines. The 30-degree cutting edge provides controlled crush cutting performance for a wide range of lightweight and flexible web materials.
They are suitable for cutting paperboard, adhesive tapes, labels, metal films, flexible laminates, composite materials, and nonwoven fabrics (NWF). Standard diameters range from 35 mm to 180 mm, with custom dimensions available according to customer drawings or machine specifications.
WINGCHONG KNIFE manufactures custom crush cutting knives using high-quality tool steel, high-chromium steel, and other material options selected according to the cutting application.

45° Crush Cutting Knives are precision-manufactured slitting knives designed for slitter rewinders, flexographic printing machines, inspection equipment, and integrated slitting systems. The 45-degree cutting edge provides reliable crush-cutting performance for a wide range of lightweight and flexible web materials.
They are suitable for cutting lightweight paperboard, adhesive tapes, labels, metal foils, laminates, flexible composites, and nonwoven materials (NWF). Standard knife diameters range from 35 mm to 180 mm, while custom dimensions can be manufactured according to customer drawings, machine specifications, and application requirements.
WINGCHONG KNIFE manufactures custom crush cutting knives using high-quality tool steel, high-chromium steel, and other suitable steel grades selected according to the material and cutting conditions.

60° Crush Cutting Knives are precision-manufactured slitting knives designed for rewinders, flexographic printing machines, inspection equipment, and slitting machines. The 60-degree cutting edge provides controlled crush-cutting performance for a wide range of paper, film, composite, and nonwoven web materials.
Manufactured from K100 and 100Cr6 high-quality steels, these knives are suitable for cutting lightweight paperboard, adhesive tapes, labels, metal films, flexible laminates, composite materials, and nonwoven fabrics (NWF).
Standard knife diameters range from 35 mm to 180 mm, with custom dimensions available according to customer drawings, machine specifications, and application requirements.

Hardened Screw Locking Knife Holders are precision components designed for shear slitting systems, slitter rewinders, rewinders, and slitting machines. They are used to securely mount dished knives on the upper knife shaft and maintain stable cutting pressure against the bottom knife.
Manufactured from high-strength special steel with hardening heat treatment, these knife holders provide enhanced hardness, strength, and wear resistance for continuous industrial slitting applications.
The holder features a screw-locking and snap-ring retaining system for secure knife mounting. Each holder is supplied with a spring and snap ring, while different spring specifications can be selected according to the material being cut and the required cutting pressure.
WINGCHONG KNIFE can also manufacture matching dished knives, bottom knives, counter sleeves, and related slitting components to provide a complete and dimensionally compatible shear slitting solution.

Screw Locking Knife Holders are precision components designed for shear slitting systems, rewinders, slitter rewinders, and slitting machines. They securely mount dished knives on the upper knife shaft and maintain stable knife positioning during operation.
Manufactured from high-strength special steel, the holders receive specialized surface treatment to improve corrosion resistance and wear resistance, supporting reliable performance in continuous slitting applications.
Each holder is supplied with a spring and snap ring. Spring specifications can be selected according to the cutting application, including spring length, wire diameter, and operating tension. The appropriate dished knife geometry and steel grade should also be selected according to the material being processed.
The knife holder and dished knife form the upper section of a shear slitting unit, working against the bottom knife installed on the bottom shaft to achieve precise and stable shear cutting.

Self Locking Knife Holders are precision components designed for shear slitting systems, rewinders, slitter rewinders, slitting machines, and inspection equipment. They are used to securely mount dished knives on the upper knife shaft and maintain stable cutting pressure during operation.
Manufactured from high-strength special steel with a black oxide finish, the holders provide improved corrosion resistance and wear resistance for demanding industrial applications.
The holder features a self-locking ball mechanism that engages automatically when the machine starts, helping maintain secure knife positioning even when the shaft locking mechanism has not been fully engaged. This design provides an additional level of operational safety and reliable knife retention.
Each holder is supplied with a spring and snap ring. Spring specifications can be selected according to the material being processed and the required cutting pressure.
