Yeshun differentiates between asymmetrical and symmetrical plate rolling machines to suit diverse needs. Symmetrical machines have two lower driven rolls and one upper roll, ideal for uniform bending of medium-thickness plates (up to 30mm). Their balanced design ensures even pressure distribution, making them suitable for cylindrical parts. Asymmetrical machines, with offset rolls, excel in pre-bending plate ends and handling thicker materials (up to 50mm). The asymmetrical layout allows for greater bending force and flexibility in forming conical or asymmetrical shapes, making them preferred for complex components in industries like pressure vessel and pipe manufacturing.
