the most important decision is how to choose the press brake supplier.maybe the price is not main problem but the machine quality.because they cost so much money ,of course, they hope to use longer time.however,how to judge the quality of one company? it is very difficult question. now, let us give you a idea. if one company can produce the press brake with big capacity,generally speaking,its quality would not be bad.for example,500 tons press brake as attached.this can prove the ability of press brake factory.

Another idea is to ask if they can produce two press brake connected machine,so,they can work longer parts,for example,12000 mm length.small factory can not do this at all. if you can find some factories have this ability,yes,you can take more confidence for them.
