As automakers increasingly rely on lightweighting and advanced structural materials to achieve vehicular fuel efficiency goals. the use of materials with tensile strengths of more than 550kgf/mm2 continues to grow. Research shows advanced high-strength steels to be the fastest-growing material in automotive applications.
The challenge of attaining the flatness required to properly feed high yield strength into the press has been largely ignored. HongEr Decoiler Straightener Feeder 3 in 1 machine provides prefect solution for straightener feeder.
Straightening materials with yield strengths of more than 550kgf/mm2 requires greater forces than for those with lower strengths. So straightening feeding
roller adopted material GCr15 with hardness of HRC 60±2.
