Custom Rollforming Lines

Custom Design and Manufacture of Rollforming LInes

Click here to learn more

In roll forming almost everything is considered custom. What makes it unique and really custom are the endless combinations between: roll formed product shape (S), material mechanical properties (MMP), different material thickness – same profile (MT), holes pattern and notches (H&N), (HL) holes location and sizes within certain length, roll forming machine design type (RFMT), quality (RFMQ) and age (RFMA), (LS) line speed, line configuration – pre-cut or post cut (LC), cut to length accuracy (CTL) etc & etc. In this formula a custom roll forming product (CRFP) is a function of all these variables:

CRFP = f(S + MMP + MT + H&N + HL + RFMT + RFMQ + RFMA + LS + LC + CTL+ etc.)

Within the same shape similarity, small change in one of the above variations creates brand new combination and different solutions. What is the right solution for your product?
