Decision tree

Building a linked factory line with NC600?

NN300 is the standard downstream joiner.

Daily volume under 800 frames with mixed profiles?

NN400 retains flexibility and lower capital.

Need four corners without walk-around?

NN300 eliminates repositioning vs NN400 single-corner cycles.
