Main Features
- Reinforced Piercing Tip Structure: Thickened sharp tip design easily penetrates multi-layer woven ton bags and heavy packaging materials, avoiding slipping and incomplete cutting during high-speed automatic unpacking.
- High Abrasion Resistant Alloy Matrix: Premium Cr12MoV tool steel with optimized hardening resists long-term fiber abrasion and minor impact from sand or granular impurities inside bulk bags.
- Precision Positioned Mounting Holes: CNC-drilled fixing holes match machine tool holders with zero offset, ensuring stable blade alignment and preventing loosening during continuous cyclic operation.
- Smooth Low-Resistance Cutting Edge: Mirror-polished bevel edges reduce cutting friction, prevent fiber snagging and fraying, and minimize packaging debris mixing into bulk materials.
- Stress-Relieved Impact Toughness: Cryogenic treatment eliminates internal steel stress, balancing edge hardness and body toughness to resist chipping when hitting hard foreign objects in bags.
Advantages
- Clean Contamination-Free Unpacking: Sharp, smooth edges cut through packaging cleanly without tearing, reducing fiber debris and foreign material contamination of bulk contents.
- Longer Production Uptime: Superior wear resistance significantly extends blade service life, cutting the frequency of blade replacement and equipment downtime.
- Stable Automated Operation: Precise mounting dimensions ensure vibration-free running on automatic unpacking lines, supporting continuous high-volume bulk material discharge.
- Broad Packaging Compatibility: Performs reliably on PP woven ton bags, FIBC bulk bags, jute sacks, paper-plastic composite bags and other heavy packaging types.
- Cost-Effective OEM Alternative: Factory-direct pricing delivers OEM-grade durability and precision at substantially lower procurement costs for bulk handling facilities.
Product Applications
- Machine Compatibility: Automatic bulk bag unpackers, FIBC bag opening stations, ton bag discharging systems, automated unpacking production lines.
- Material Compatibility: Woven PP ton bags, FIBC bulk sacks, jute bags, heavy plastic sacks, paper-plastic composite packaging, woven fabric bags.
