With the DALLAN D4J lines our customers use the parametric programming and the versatility of the Dallan punching machines to pre-punch the coil before the forming process. In this way the profiles come out of the machine already cut to size and with the holes in the exact position for the assembly and application of the fixing brackets.
The Dallan flexible coil punching machines can also be inserted in line with existing roll formers to make the production line, as a whole, much more flexible.
