Low-Carbon Factory Transformation Case: Full-Line Energy-Saving Servo Punch Upgrade and Workshop Energy Consumption

Case Cycle: May 2025 – May 2026

Enterprise V is a professional supplier of new energy photovoltaic hardware and energy storage equipment stamping parts, with a total of 10 stamping production lines. For a long time, the factory adopted mixed production of mechanical punches and ordinary servo punches, with high comprehensive power consumption, unable to pass the green factory audit of head photovoltaic groups, and faced the risk of being excluded from the green supply chain. The enterprise launched a one-year full-line energy-saving upgrade and low-carbon optimization project, completed the elimination of high-energy-consumption equipment and intelligent energy-saving transformation, and achieved substantial results in electricity cost reduction, carbon emission reduction and green qualification certification.

1. Eliminate all high-energy-consumption mechanical punch presses, replace all old equipment with new-generation energy-saving permanent magnet servo punch presses with energy recovery function;
2. Carry out full-station stamping parameter optimization calibration, formulate energy-saving stroke standards for photovoltaic aluminum plates, copper strips and stainless steel parts, eliminate invalid stamping strokes and excessive pressure loss;
3. Build workshop power consumption refined management system, equip independent power meters for each production line, realize real-time monitoring and abnormal early warning of single-line energy consumption;
4. Optimize production scheduling logic, concentrate continuous production to avoid frequent start-stop and long-time idle standby of equipment, reducing invalid standby power consumption;
5. Cooperate with third-party carbon accounting institutions to complete factory carbon footprint assessment and obtain official low-carbon factory certification.

After one year of systematic low-carbon energy-saving transformation, Enterprise V has achieved a qualitative leap in energy efficiency, cost control and green qualification. The unit stamping energy consumption is reduced by 65.4%, the annual electricity cost is saved by more than 170,000 US dollars, and it has successfully obtained the official certification of green manufacturing enterprise. In the future, the enterprise will further introduce intelligent energy-saving scheduling system, realize automatic matching of optimal energy-saving parameters for different products, build a zero-carbon intelligent stamping workshop benchmark, and continue to lead the low-carbon and green upgrading of the global punch press stamping industry.
