Main Features
Precision Serration Grinding: Utilizing advanced CNC grinding technology to achieve extremely accurate and uniform tooth geometry along the entire length of the long straight toothed knives.
Matched Tooling System: Capable of manufacturing the entire assembly—the cutting blade and the complex profile clamping die tooling—to ensure perfect alignment and function.
Functional Edge: The custom length tear notch blades design provides the clean, easy-open feature required by modern packaging standards.
High-Speed Material: Blades are typically manufactured from HSS (HSS impulse sealing cutter) to withstand the abrasive nature of films and the rapid cutting cycles.
Custom Tooth Profile: Specialization in non-standard tooth shapes and pitches based on the film type and sealing technology (heat seal, impulse seal).
Advantages
Flawless Seal & Cut: Perfect tooth-to-die engagement ensures a strong package seal concurrent with a clean cut, minimizing product failure.
Extended Life in Automation: High-grade materials ensure durability and reliability in high-cycle form fill seal machine serrated blades applications.
Reduced Film Drag: Precise tooth geometry minimizes friction and drag on the film during cutting.
Complete System Solution: Sourcing both the cutter and the mold from one expert manufacturer simplifies procurement and guarantees compatibility.
Product Specifications
Cutting Blades: Top and bottom serrated packaging cut-off knives for horizontal and vertical form-fill-seal machines.
Dies/Molds: Matching die/bar components (complex profile clamping die tooling) for sealing and perforation.
Trimming: Custom serrated trimming bar for creating decorative or functional edges on wide webs.
Customization: We require detailed CAD drawings for the tooth profile, length, and mounting hole pattern.
Why Choose Us
