Slitting challenges for different materials
1. PE film
◦ Material properties: soft, highly ductile
◦ Main challenges: The edges are easy to stretch and deform, and static electricity is easy to generate
2. PET film
◦ Material properties: high hardness and good dimensional stability
◦ Main challenges: brittle edges and high slitting accuracy requirements
3. Aluminum foil
◦ Material properties: metal properties, non-ductility
◦ Main challenges: edge burrs, fast wear of slitting tools
Multi-material slitting solutions
1. Tool system optimization
• PE/PET: Use a circular knife for slitting with a knife angle of 25-35° to ensure a clean cut
• Aluminum foil: Uses carbide tools with a knife angle of 15-25° to reduce burrs
• Quick tool change system: Realize quick switching between different materials
2. Tension control system
• PE: Low tension control (5-15N) to prevent tensile deformation
• PET: Medium tension (15-30N) for stability
• Aluminum foil: high-precision micro-tension control (3-10N) to avoid breakage
3. Winding technology
• Surface winding: suitable for soft materials such as PE
• Center winding: suitable for hard materials such as PET
• Air expansion shaft winding: special for aluminum foil to prevent material deformation
4. Edge treatment
• Static Elimination System: Essential for PE/PET slitting
• Online monitoring: Detect the quality of the slitting edge in real time
• Burr treatment unit: special post-processing unit for aluminum foil
Equipment selection suggestions
1. Multifunctional Slitting Machines: Equipped with adjustable tool systems and tension ranges
2. Modular Design: Easy to replace key components based on materials
3. Intelligent Control System: Automatically recognizes material properties and adjusts parameters
Maintenance points
• Regularly check for tool wear, especially after handling aluminum foil
• Keep the working environment clean to avoid dust affecting the slitting quality
• Clean the equipment between different material slitting rooms to prevent cross-contamination of materials
With these solutions, modern film slitting machines can efficiently process a wide range of materials, from PE to aluminum foil, meeting the needs of high-precision slitting in different industrial sectors.
