How do small width steel coils come out? Are they produced that narrow width at the beginning? No, they are generated by big width coil at first like 2000mm. A flat sheet of material is also not actually produced by a mill as a flat sheet. In reality, a flat sheet of material starts its life as part of a coil of material. These steel coil or sheet manufacturers normally have some big production lines in their factory named cut to length production line or slitting line.
A Cut-To-Length Production Line / Blanking Line will uncoil the material, level it, and then cut it to the required length and stack it. The end product produced by a Cut-To-Length Production Line / Blanking Line is a flat sheet of material cut to a very precise length tolerance. You can see the below photo for a fast look:
However, this kind of production line cost quite high, not every company can afford it if you don’t have large output and budget, although our engineers can design different levels of cut to length production line according to the customer’s wishes and budget. So I recommend the economic alternative choice for customer as follows photos.
These are separate large models of decoiler, straightener, NC servo roll feeder and shearing machine, so-called simply cut to length production line. This line is also automatic in loading, uncoiling, straightening, feeding and cutting. Just the finished product stacking part is not automatic like the high cost production line I introduced above. Need to add a conveyor to feed the sheet after cutting. And then place a material collection box at the end of the conveyor. These two equipments make this simply cut to length production line fully automatic, just like the below pic shows:
Let me show you one shipment of 1600*4mm simply cut to length production line from our Italian client. That decoiler is too big to be packed by iron shelf. And one forklift is not enough to put it in the 40’HC container, need one big forklift to lift the other smaller forklift to push these big machines inside the container.
