Notes Before Ordering a Cold Bending Machine

When choosing a cold bending machine, the first question should not be the price. Buyers need to know the profile first: I-beam, channel steel or another section, then confirm the bending radius and the expected batch size. In tunnel and metro projects, this equipment bends steel sections by using hydraulic power to drive rollers, so the original material strength is kept during cold forming. A common power range is about 8 to 16 kW, and the minimum bending radius can reach around 2 meters. Hydraulic models are often used where accuracy and output matter. CNC models suit projects that need repeatable curves and less manual adjustment. Manual models still have a place in small jobs or testing rooms. For Baoqiang Machinery, clear drawings and site data help the team decide which machine structure, control method and service plan should be offered before production starts, during installation and later maintenance checks.
