[Technical Introduction] Progressive Die Processing of High-Strength Steel Sheets

We have devised the mold for pressurizing the bent R section to suppress springback.

At Sanyo Electric Co., Ltd., we offer "progressive processing of bending and forming high-strength steel plates." When it comes to high-strength steel plates, concerns such as wrinkles, cracks, and springback arise compared to general materials. Even with 440MPa high-tensile steel plates, an increase in springback is expected compared to general materials, necessitating considerations for springback in the mold design. As a countermeasure, we have implemented techniques in the mold, such as dispersing the bending process and applying pressure to the bending radius, to suppress springback. 【Usage Range and Conditions】 ■ Ensure contour accuracy of R shapes within 0.5 ■ Ensure bending perpendicularity within 0.3 ■ The size of products that can be processed varies depending on plate thickness, etc. (consultation available) *For more details, please refer to the PDF document or feel free to contact us.
