U bend can achieve automation in many production environments. Pros: Improve production efficiency: automatic press brake can work constantly, reducing human intervention time. Improve precision: the automation system can accurately control the pressure, speed, and angle, reducing the production error rate. Reduce labor intensity: reduce human repeatable labor, and improve working environment and safety. Cons: High investment: the initial investment in purchasing automatic equipment is high. Complex maintenance: the repair and maintenance of automatic press brakes need professional knowledge and technology support. Low flexibility: it is relatively large to adjust automatic production line cost and time for products with small-scale and multiple varieties.
