Jingjiang Daming, one of Daming’s eleven steel processing centers, has completed a complex, large-scale project that marks a key milestone in its transformation from a specialized metal parts processor to a full-service manufacturing provider. The project, which involved producing over 3,000 stainless steel plates for SCC CNCEC, tested the company’s ability to handle high-precision, technically challenging work and highlighted its growing expertise in integrated service solutions.

The stainless steel gratings, known for their intricate welding requirements and high precision, were the perfect challenge to showcase Daming’s advanced manufacturing capabilities. These products serve as a critical component in large-scale industrial projects, where both structural integrity and precision are essential.

Overcoming Challenges with Precision and Innovation

The project team at Daming faced several technical challenges, from precise part cutting to controlling material deformation during welding. With these difficulties in mind, Daming’s technical department swiftly formed a specialized task force to tackle each challenge head-on, ensuring that every phase of the project met high standards of quality and efficiency.

Leveraging 3D Digital Technology for Accuracy

One of the key innovations in this project was the use of 3D digital assembly technology, which allowed Daming to simulate the entire assembly process before starting production. By visualizing over 3,000 sheet metal pieces in a digital environment, the team was able to identify potential issues early, optimize the welding sequence, and prevent rework—ultimately improving both assembly efficiency and the quality of the final product.

Precision Cutting: Millimeter-Level Control

To ensure the high precision of each grating plate, the project team utilized specialized cutting equipment, optimized for millimeter-level accuracy. By carefully calibrating the machines and refining the cutting process, Daming ensured that each semi-finished product met the strict requirements for the next phase of production, laying the foundation for smooth, efficient assembly.

Precision Assembly: Ensuring Alignment and Consistency

Assembling the large stainless steel into a grating posed its own set of challenges, particularly in maintaining tight tolerances and precise alignment. Daming addressed this by using specialized tooling fixtures and laser positioning systems, which allowed the team to accurately align and splice each unit. This technology ensured that the gaps between components stayed within acceptable limits, improving both the speed and consistency of the assembly process.

Managing Deformation During Welding

Welding stainless steel, particularly at large scales, can result in material deformation, which affects the overall quality and stability of the product. To address this, Daming developed a multi-step solution involving tooling fixation, segmented symmetrical welding, real-time temperature monitoring, and post-weld stress relief. This approach allowed the team to control deformation effectively, maintaining the flatness and stability of the grating structure.

A Major Step in Daming’s Service Upgrade

The successful delivery of this project represents a critical turning point in Daming’s evolution. It not only showcases the company’s technical expertise in managing complex, large-scale manufacturing projects but also solidifies its transformation into a comprehensive service provider. Through the integration of advanced technologies, including 3D assembly simulation, Daming has taken a major step toward offering end-to-end solutions for clients across various industries.

This achievement has also garnered significant recognition from SCC CNCEC, with the precision, stability, and quality of the stainless steel grating receiving high praise. For Daming, this successful project is proof that investing in cutting-edge technology and process optimization is key to delivering high-end, reliable products that meet the most demanding industry standards.

Fostering Future Growth Through Technology and Innovation

As the company moves into 2026—the first year of China’s 15th Five-Year Plan—Daming is committed to continuing its push for innovation. The company plans to expand its use of digital and green technologies to drive its transformation and provide sustainable, high-quality solutions for clients. The successful completion of the grating project sets the stage for Daming to leverage its technological advancements further, especially in 3D assembly simulation and other digital tools that address complex manufacturing challenges.

By continuing to focus on precision and technological excellence, Daming will remain a key player in the manufacturing sector, contributing to the industry’s high-quality development while helping clients improve efficiency and reduce costs.
