Recently, the first precast success of the fully automatic hydraulic box girder mold, constructed by Hebei Xindadi Mechanical and Electrical Manufacturing Co., Ltd., was achieved in Heilongjiang Iron Investment. This project is located in Yichun City, Heilongjiang Province, and is an important part of the Heha Expressway. It is the first production line in the region to use fixed side molds and mobile bases to produce box girders.

The production line utilizes a hydraulic automatic box girder mold with the industry’s first “three-separator side mold” integrated automatic demolding function. The box girder mold adopts modular design and features split separator end plates. The hydraulic cylinder adopts a digitized visual control program for stroke, with multiple cylinders synchronously operating for smooth opening and closing. This enables fast mold installation and efficient production of box girders, allowing for quick delivery of products. The mold is made of polished stainless steel, resulting in smooth and shiny product components. The attached compaction uses an automatic multi-stage variable frequency vibration compaction system, which allows for free selection of vibration areas. The entire operation is controlled using a fixed workstation and tablet computer, providing convenient and efficient operation.
The production line adopts an intelligent production system control, which monitors and predicts the production process, promptly identifying and solving any issues that may arise. This helps improve production efficiency, product quality, and stability.
