Jining, Shandong Province (Reporter Dou Bao) - In the production workshop located in Beihu Provincial Tourist Resort of Jining, Shandong Province, the fully automatic steel mesh welding machine of Shandong Zhongji Luyuan Machinery Co., Ltd. is operating at high speed, completing the welding and forming of a standard steel mesh within 30 seconds. This intelligent equipment, integrated with 25 patented technologies, has become an "efficiency engine" in the global infrastructure field, thanks to its welding speed of 30-65 rows per minute and mesh error of less than 2mm.

Founded in 2016, Zhongji Luyuan is a national high-tech enterprise. With a registered capital of 50 million yuan as its foundation, it has been deeply engaged in the R&D of numerical control steel bar processing equipment. Its newly launched intelligent steel bar welding mesh machine adopts a PLC + touch screen control system. Operators can accurately set mesh size and welding parameters through the touch screen, and a single device only requires 1 worker to achieve continuous production. Equipped with a pneumatic wire feeding device driven by a servo motor, the vertical wire positioning error is controlled within 0.5mm. The horizontal wires are accurately fed one by one through a disc-type blanking system driven by a stepping motor, fundamentally solving the precision problem of traditional manual welding. In terms of welding performance, this equipment demonstrates strong adaptability: the welding wire diameter ranges from 3.5mm to 8.0mm. Through the modular resistance welding module and forced water cooling system, the service life of the electrode is doubled, which can meet the steel mesh processing needs of different scenarios such as bridges, tunnels and residential buildings. A person in charge of a project department of China Railway revealed that in the construction of the Yuxi-Mohan Railway, the welding mesh machine of Zhongji Luyuan improved efficiency by 60% compared with traditional equipment, and saved more than 800,000 yuan in labor costs for a single project.

Relying on a sound technical system, Zhongji Luyuan has established long-term cooperation with central enterprises such as China Railway Construction Corporation and China State Construction Engineering Corporation. Its products are exported to nearly 100 countries and regions including South Korea and Israel. In a highway project in South Africa, its equipment operated without failure for three consecutive months, and the welded steel mesh passed the local strict seismic strength test with a qualification rate of 100%.
"Our core competitiveness lies in transforming complex processes into intelligent operations," said the person in charge of the enterprise. Zhongji Luyuan, relying on the intelligent control system built with 8 software copyrights, can realize automatic matching of welding parameters and fault early warning. At present, the company has applied for 20 policy supports and is accelerating the R&D of a new-generation equipment capable of welding thick steel bars of Φ20mm.
With the in-depth advancement of "Made in China 2025", specialized, refined, distinctive and innovative enterprises like Zhongji Luyuan are reconstructing the industry pattern through technological innovation. Industry experts point out that its welding mesh machine reduces the labor cost of the traditional production mode by 70%, promotes the transformation of steel bar processing towards "factoryization and intelligence", and provides key equipment support for the high-quality development of global infrastructure.
