Introduction:
Thin gauge metal coil slitting line continuously decoil and slit metal coil sheet into multiple (several to dozens of) narrow strips and then recoil narrow strips up, the thin sheet slitting line requires high speed high precision.
High speed thin sheet slitting machine means slitting line speed can be 120m/min, 150m/min, 200m/min, fully automatic controlled by PLC.
Steel coils (Cold Rolled steel, Galvanized steel, PPGI steel,stainless steel coil), non-ferrous metal coils(aluminum coil, copper coil)slitting in small thickness ranging 0.20-3.0mm require high precision +/-0.10mm to +/-0.15mm slit width tolerance.
Continuous slitting thin metal coil plate at high speed in high precision need each unit of slitting line should be custom designed, machined, assembled and installed to ensure smooth slitting process, meanwhile, must consider special characteristics of thin metal strip material.
