Aogang Machinery Co., Ltd.
Aogang Tube Mill provided a customized 150×150mm direct-forming square tube production line for a large European steel structure manufacturing group (anonymity requested by the client). This successfully replaced the company's outdated, unstable, and frequently malfunctioning equipment. The new line met the client's multiple requirements for high efficiency, high precision, intelligent control, and fast die changeovers.
This machine utilizes a heavy-duty, high-strength frame and a German-branded servo drive system, ensuring long-term stable operation, reducing equipment failure rates by 80% and increasing annual production capacity by approximately 40%.
Weld seam strength exceeds 95% of the parent material, and with real-time online quality monitoring, the product qualification rate reaches 99.5%, ensuring the reliable quality of pipes used in steel structure projects.
This quick-change mold design allows for format changeovers in less than 30 minutes, enabling flexible production of square and rectangular pipes ranging from 120×120mm to 180×180mm, enhancing production flexibility.
Equipped with an energy-saving motor and intelligent power regulation system, it consumes 25% less energy than the original equipment. A Siemens PLC and touchscreen interface support remote diagnostics and production data traceability.
