Box Sealing Machine Toothed Blade Factory Supplier Packaging Carton Sealer Serrated Knife
Products ：The carton sealer serrated blade is the core cutting component of the carton sealer equipment. It is mainly used in the automated packaging production line to quickly cut the tape and complete the sealing of the carton. Its serrated design can effectively prevent the tape from sliding during cutting, improving the efficiency and stability of box sealing.
Product Name: Carton Sealer Serrated Blade /Box Sealing Machine Notched & Toothed Blade
Material: SUS304 stainless steel, High carbon steel, high-speed steel, tool steel, alloy steel, 420J2 (3Cr13), HRC 52-55, 440C,(9Cr18MoV)
Size: Thickness: Between 3 and 80 millimeters (customizable)
Type: High-temperature quenching makes the cutting edge sharp; Vacuum heat treatment, PVD coating, CNC grinding
Features:
- Sawtooth design: Sawtooth shapes (tr angular, wavy, etc.) can enhance cutting efficiency, prevent tape adhesion reduce the contact area between the blade and the tape, and lower wear.
- High hardness and wear resistance: The material hardness usually reaches HRC 50-60, making it suitable for high-frequency cutting. Surface polishing or coating treatment (such as titanium plating) can extend the service life.
- Compatibility: Compatible with various box sealing machines (such as semi-) automatic and fully automatic box sealing machines), customizable, safe and stable, with sharp sawtooth edges but not prone to chipping.
Application Scenario: Paper industry blades, steel and metal urgy blades, rubber and plastic industry blades, electronics industry blades, packaging industry blades, wood industry blades, food industry blades, textile industry blades, etc., have a wide range of applications.
Selection criteria:
Consider non-standard customization: For special materials or unique cutting requirements, We offer non-standard customization services.
To quickly compare the primary materials we offer, here is a summary table:
| Material Type | Typical Hardness (HRC) | Key Advantages | Limitations | Ideal For |
| High-Speed Steel (HSS) | 60-68 | Excellent toughness, good wear resistance, cost-effective. | Lower wear resistance than carbide, requires more maintenance. | General-purpose metalworking, woodworking, plastic cutting. |
| Tool Steel (e.g., SAE1095) | 58-62 (Hardened) | High strength, excellent wear resistance, good sharpness. | Less resistant to high temperatures than HSS or Carbide. | Springs, hand tools, scrapers, industrial cutters. |
| Carbide / Tungsten Carbide | 60-65 (Blades) | Exceptional hardness & wear resistance, high heat resistance. | Brittle, higher cost, complex manufacturing. | Hard materials, abrasive non-ferrous metals, high-volume production. |
| Stainless Steel | Varies (e.g., 420, 440) | Excellent corrosion resistance, durable, hygienic. | Generally not as hard as tool steels or HSS. | Food processing, medical instruments, wet environments. |
| Ceramic | N/A (Extremely Hard) | Superior edge retention, corrosion resistance, hygienic, lightweight. | Fragile, limited cutting capacity, higher cost. | Precision cutting in specific industries (e.g., textiles, packaging). |
