3-Roll Mechanical Plate Bending Machine
Our series of 3-roll mechanical plate bending machines are designed to accommodate the precise bending requirements of metal plates. Available in symmetrical, asymmetrical, and vertical configurations, they are pivotal in cold rolling cylindrical and arc shapes with exactitude, catering to various mechanical fields including, but not limited to, boiler production, chemical processing, mining, infrastructure development, and naval construction.
The symmetrical 3-roll benders are versatile units, ideal for processing steel plate thicknesses from 3 to 40mm, delivering consistency across various bending operations. The asymmetrical benders excel with their dual functionality, enabling sophisticated pre-bending and rolling processes encased within a design that emphasizes ease of operation and maintenance for steel plates from 1 to 10mm thick.
