The Cut To Length (CTL) Combined Line from Shijiazhuang Faith Machinery Co.,Ltd offers precision sheet cutting and subsequent handling systems in a unified platform. CTL lines are indispensable for manufacturers of flat panels, electrical enclosures, and HVAC components. This article delves into CTL line design, cutting technology, customization, and support services that maintain consistent sheet dimensions and edge quality.
Decoiler and Leveler
Motorized decoiler positions coils with up to 30 ton capacity.
A horizontal leveler with hydraulic roll adjustments flattens material, removing coil set and camber defects.
Feeding System
Pinch rolls transfer strip from leveler to shear section, maintaining accurate positioning for cut‑to‑length operations.
Shearing Units
Flying Shear: Pneumatic or hydraulic flying shears synchronized to line speed for continuous, burr‑free cuts up to 8,000 mm.
Guillotine Shear: Single cut shear for lower speed or thicker gauge applications, offering precise square edges.
Stacking and Handling
Adjustable stacking arms and push‑off devices organize sheets into stacks, with automatic bailers or strap units for load preparation.
Length Accuracy: Closed‑loop feedback from linear encoders maintains cut‑length tolerances within ±0.5 mm, even at high speeds.
Edge Quality: Hardened shear knives with automatic backlash compensation ensure clean edges free of burrs or roll‑over defects.
Sheet Flatness: Post‑cut flattening conveyors optionally incorporate turn‑through leveling for sensitive metal grades.
Thickness and Width Capacities: Lines configured for strip thicknesses from 0.4 mm to 6 mm and widths up to 2,500 mm.
Material Compatibility: Carbon steel, stainless steel, aluminum, and pre‑painted steel accommodated through adjustable roll pressures and knife clearances.
Specialty Options: Inline marking stations, sheet perforation units, and protective film applicators can be added per customer requirements.
PLC and HMI: Centralized touchscreen control allows recipe storage for different sheet dimensions, material grades, and production speeds.
Production Reporting: Automatic logging of cut counts, average cycle times, and downtime incidents feeds into performance dashboards.
Remote Support: Secure remote access enables diagnostic review and parameter tweaking by Faith Machinery technicians.
Installation Services: Full project management from site preparation through final commissioning, aligning mechanical, electrical, and hydraulic systems.
Operator Training: On‑site and remote training modules covering safe operation, routine shear maintenance, and troubleshooting.
Maintenance Packages: Preventive maintenance schedules address wear items—shear blades, conveyor belts, hydraulic hoses—to sustain line availability.
Spare Parts Logistics: Dedicated parts warehouse ensures rapid shipment of critical components to minimize production interruptions.
