The new technology for advanced dynamic 3D roll forming can produce profiles with asymmetrical cross-sections both in depth and width, allowing for an immense variety of shapes through a rotational and traversing movement of all the roll forming heads. In contrast to many other processes, the sheet metal is not thinned out during roll forming.
A numerical control system allows you to manage the more than 100 dynamic axes of the variable section roll formers, and the operator can freely program the machine, obtaining the requested section variations. One of the reasons that the method is so valuable for manufacturers is that machines are designed to be used with cold forming steel at very high strength levels. In fact, the higher the strength of the steel the more suitable it is for roll forming.
3D roll forming can be applied to low thickness materials (1.0mm), for the construction and automotive sector, and also to high thickness materials (up to 11.0 mm) for the transport sector (beams of lorries, trailers)
We also provide cold roll forming machine for such technologies involving:
1. Cutting rectangular blanks, checking and correcting camber
2. Shaping blanks, removing excess material
3. Roll forming with variable section
4. Calendering and piece perforation
3D roll forming technology changes your perception of profiles, by introducing an additional degree of freedom in the roll forming process.
