3D roll forming technology research and developmentTapered shaping technology research and development
Honley car long-term R & D team and Steel (CHINA STEEL CORPORATION) (a listed company stock code: 2002) and government units Foundation Metal Industries Research and Development Center to promote, participate in a number of R & D 3D roll forming technology solutions and plans.A continuous production process is divided into two kinds of closed and open, rolling away a lot of the traditional 2D roller section modeling application components, solves the problem of high-strength steel resilience, advanced 3D technology is still developing roll，After the production of the future can be applied in varying parts of the cross-section shape, produce a variety of cross-sectional shape of the parts to Open style more common, with a laser or high-frequency welding forming a tubular member that is welded closed closed type, Roll forming accuracy up to 0.125mm, trends: towards the manufacture and processing of steel AHSS.
3D roll (variable cross-section) for automotive applications status as shown below：
