Slotter Knives
Slotter Knives for Precision Slitting & Cutting
Slotter knives are high-precision circular cutting tools widely used in converting and packaging industries for bottom slitting, narrow slit cutting, trimming, and finishing. They are essential in applications where accurate cut quality, clean edges, and high production speed are required.
ZHONGJIAN TECH slotter knives are engineered for stable performance, enhanced wear resistance, and long service life. Our knives are designed to deliver consistent cutting results across a wide range of materials including paper, film, foil, and composite webs.
Typical Slotter Knife Applications
ZHONGJIAN TECH slotter knives are commonly used in:
- Bottom slitting and narrow strip cutting
- Laminated film and foil trimming
- Bag making and multi-point slit cutting
- Packaging material profiling
- Industrial web processing and converting
These knives help improve cut quality and material yield while reducing maintenance and changeover time.
Blade Materials & Construction
ZHONGJIAN TECH slotter knives are manufactured from premium tool steel materials selected for each application:
- DIN 1.2379 / D2 tool steel – The standard material for most slotting applications, offering excellent wear resistance and edge stability, ideal for paper and converter film cutting.
- DIN 1.3343 / M2 (High-Speed Steel) – An optional material for specific cutting environments that demand improved heat resistance and longer tool life. M2 is less commonly used due to cost but great for high-speed slitting or abrasive materials.
Each blade is precision ground with controlled hardness for optimal cutting performance and long life.
Typical Slotter Knife Sizes & Specifications
ZHONGJIAN TECH slotter knives are available in a range of standard and custom sizes to suit different machines and production lines.
- Outer diameter: 50 mm – 300 mm (or as specified)
- Thickness: 1.5 mm – 6 mm (application dependent)
- Bore diameter: Custom based on shaft size
- Edge geometry: Precision ground for minimized burr and chatter
All slotter knives are manufactured to tight tolerances to ensure consistent cut quality and reliable operation.
Note: Custom sizes and hole configurations are available upon request based on your machine model or drawing.
