Multi Blanking Line Types of material:
Carbon Steel, stainless steel, aluminium, non ferrous metals and alloys.
Cold rolled, hot rolled, pickled, galvanized, dried, oiled, any coating and metals with sensitive surfaces.
As the coil build up, the recoiler rpm correspondingly goes down to keep desired constant line speed. This process goes on until the end of coil on uncoiler. The slitted coil is pushed on the exit coil car through a pusher plate operated by hydraulic cylinder. The side slitted scrap is wound on the scrap winder units provided on both sides of the slitter.

Multi Blanking Line working process:
Steel coils are transferred by an entry coil car and loaded onto an uncoiler. From uncoiler the strip proceeds through a five-high precision leveler designed to level steel within the desired material gauge range and yield strength. The strip then proceeds through a squaring unit and precision roll-feed unit to the high speed shear, where it is cut to required length. The cut sheet then moves to float sheet stacker where it is stacked on a pallet and is then moved onto the semiautomatic packaging line for wrapping.
Benefits of Multi Blanking Line
- Minimal tooling preparations and higher productivity rates
- Energy efficient
- Reduced operating costs
- High in speed and strength
- High input and output rates
- Extreme sheet flatness due to high precision levelers
- Exact cutting accuracy
