Shijiazhuang Faith Machinery Co.,Ltd’s Metal Coil Slitting Machine is designed to handle a wide variety of metal substrates—including carbon steel, stainless steel, aluminum, copper, and alloy strips—providing high‐precision slitting capabilities for demanding applications in electronics, construction, and automotive industries.
Coil Handling System
Motorized coil cars position coils onto hydraulic mandrel decoilers.
Active tension arms maintain strip straightness as the material enters the leveler.
Tension Leveling Section
A multi‐bar leveling stand equipped with independent hydraulic crown control corrects residual stresses and thickness variations.
Slitting Module
Hardened knife shafts support rotary knives with precise ground cutting edges.
Knife holders slide on linear guides and lock in place with pneumatic actuators for rapid changeovers.
Recoiler Assembly
Variable‐frequency recoilers synchronize with line speed to maintain consistent strip tension during rewinding.
Coil centering guides ensure uniform winding, reducing telescoping and uneven builds.
Automatic Knife Gap Monitoring: Strain gauges on the knife shafts detect slitting forces; the PLC adjusts knife separation to maintain optimal clearance.
Surface Protection Measures: Non‐marking roll sleeves and low‐friction slide pads prevent abrasion on coated or polished surfaces.
Line Speed Adaptation: The system automatically adjusts strip tension and knife engagement timing when switching between materials of varying thickness or hardness.
Substrate Compatibility: Adjustable roller materials and surface finishes accommodate soft metals (aluminum, copper) and high‐strength alloys without marring.
Width and Thickness Ranges: Standard models process thicknesses from 0.1 mm to 4 mm and widths up to 2,000 mm; heavy‐duty variants extend to 12 mm thickness.
Micro‐Slitting Capability: Optional high‐precision frames allow slit widths as narrow as 2 mm for electronic foil and specialized gasket materials.
Quick-Change Knife Cartridges: Pre-set knife cartridges reduce downtime during width adjustments, with typical changeover times under 30 minutes.
Integrated Scrap Handling: Automated choppers and conveyors manage edge trim, feeding scrap directly to balers or recycling bins.
Remote Monitoring and Diagnostics: An embedded web server provides real-time performance metrics and fault codes accessible via standard web browsers.
Shijiazhuang Faith Machinery Co.,Ltd offers comprehensive after-sales support, including preventive maintenance schedules, spare parts kits tailored to machine usage, and ongoing technical training. Through a combination of robust mechanical design and intelligent control systems, the Metal Coil Slitting Machine delivers consistent, high-quality slit coils for a broad spectrum of metal processing industries.
