Pure electric servo bending machine: green precision equipment that empowers high-end manufacturing

In the field of sheet metal processing, the bending machine is the core forming equipment, and its technological iterations have always kept pace with the transformation and upgrading of the manufacturing industry. With the deepening of green manufacturing concepts and the surge in demand for high-end processing, pure electric servo bending machines have gradually replaced traditional hydraulic bending machines with outstanding advantages such as precise control, high efficiency and energy saving, environmental protection and cleanliness, and have become the equipment of choice for high-end industries such as new energy vehicles, 3C electronics, aerospace, etc., pushing metal forming processing into a new era of intelligence and greening.
Compared with traditional hydraulic bending machines, the core breakthrough of pure electric servo bending machines lies in the innovation of driving methods. It abandons the oil transmission mode of the hydraulic system, uses a servo motor to directly drive the ball screw or rack and pinion system, and achieves precise control of the slide movement through electrical signals sent by the CNC system. This "electrically driven direct connection" design fundamentally eliminates the gap error and energy loss of hydraulic transmission. The repeatable positioning accuracy can reach ±0.01mm, which can easily meet the micron-level processing requirements of electronic components, medical equipment and other precision components. After an electronic accessories company introduced this equipment, its product rejection rate dropped sharply from 1.8% to 0.2%, which fully confirmed its high-precision advantage.

Energy saving and environmental protection are another core competitiveness of pure electric servo bending machines. Traditional hydraulic bending machines need to continuously run the hydraulic pump to maintain system pressure, resulting in high standby energy consumption and the risk of hydraulic oil leakage and contamination. However, pure electric servo bending machines only consume power when the slider is moving, with almost zero standby power consumption. The overall energy consumption is 40% to 60% lower than traditional models. Calculated based on a single device, the annual power saving can reach more than 14,000 yuan. Long-term use can significantly reduce operating costs for enterprises. At the same time, the hydraulic oil-free design makes it suitable for the needs of clean workshops such as food machinery and medical equipment, and perfectly fits the national green manufacturing development plan.

Efficient and flexible production capabilities enable pure electric servo bending machines to adapt to diversified market demands. The current manufacturing industry mostly exhibits the production characteristics of "small batches and multiple varieties". Traditional equipment takes up to 40 minutes to change molds, which seriously restricts production efficiency. The rapid mold change system equipped on the pure electric servo bending machine can shorten the mold switching time to less than 30 seconds. With the intelligent mold management system, parameter loading and switching can be completed within 1 minute, and the switching efficiency of multi-variety processes is increased by more than 80%. In addition, its slider idle speed can reach more than 200mm/s, and some models even achieve a high-speed response of 1 cut/second. The single-process processing efficiency is 50% higher than that of traditional models, and the daily processing volume can be up to 1.8 times that of traditional equipment.

In terms of application scenario expansion, pure electric servo bending machines have achieved full coverage in multiple industries. In the field of 3C electronics, it is responsible for processing precision hardware and chassis casings; in the new energy automobile industry, it provides precise bending support for battery boxes and charging pile structural parts; in high-end fields such as aerospace and medical equipment, its high-precision features ensure the processing quality of core components. Its presence can be seen from the large-scale production lines of large enterprises to the flexible processing workshops of small and medium-sized enterprises.

Market data also confirms the development potential of pure electric servo bending machines. China's all-electric servo CNC bending machine market size will reach 4.86 billion yuan in 2024, a year-on-year increase of 12.3%, and is expected to climb to 5.42 billion yuan in 2025. Domestic manufacturers such as Yawei Co., Ltd. and Yangli Group have made breakthroughs in core technologies, and their product performance has approached the international advanced level, and the process of domestic substitution continues to accelerate. In the future, with the in-depth application of AI algorithms in process parameter self-learning and remote operation and maintenance, intelligent bending units will become a new growth pole, promoting the evolution of pure electric servo bending machines to higher tonnage and more intelligent directions.

As an important part of high-end intelligent manufacturing equipment, pure electric servo bending machines are not only an upgrade of processing equipment, but also an important support for the manufacturing industry to achieve precise, green, and intelligent transformation. In the wave of industrial upgrading, it is empowering high-quality development of various industries with technological innovation and writing a new chapter in metal forming processing.
