Jingjiang Daming Records Exceptional Growth in Four-Side Cutting and High-Strength Steel Processing

Jingjiang Daming, a core processing center of Daming International Group, has reported a major year-on-year increase in its four-side cutting and high-strength steel processing businesses. This surge in production reflects the company’s continuous investment in advanced equipment, strong supply chain capabilities, and a deep commitment to technical excellence and customer-focused solutions.

Significant Growth in Four-Side Cutting Output

In the first three quarters of 2025, Jingjiang Daming’s four-side cutting production reached 18,402 tons, representing an impressive 61.4% increase compared to the same period last year.

This process involves precision trimming of all four edges of steel plates to achieve exact dimensions, straight lines, and superior flatness—critical quality attributes for downstream manufacturing applications. This technique is especially valued in industries such as automotive, shipbuilding, heavy machinery, and precision fabrication, where tight tolerances and flawless edge quality are essential.

At the heart of this growth is the VIGANO237 high-precision cutting line, a fully automated system that combines efficient processing with outstanding accuracy. The line handles the entire production process—from automatic loading, leveling, and straightening to stacking, quality inspection, and shipment—with exceptional reliability.

Key product performance indicators include:

• Flatness tolerance ≤3mm

• Burr deviation ≤0.1mm

• Diagonal deviation ≤2mm

• Length tolerance within ±2mm

• Zero deformation during cutting

These results underscore Jingjiang Daming’s ability to deliver consistently high-quality products with minimal variation, meeting the needs of customers who demand perfection in both form and function.

High-Strength Steel Processing Doubles in Volume

In parallel, Jingjiang Daming’s high-strength steel processing segment achieved a major breakthrough, with output reaching 12,639 tons—a remarkable 130.8% year-on-year increase.

This growth is largely attributed to the company’s continuous upgrade of its processing capabilities and its ability to handle a wide range of advanced high-strength steel grades. Jingjiang Daming now processes materials ranging from 3 mm to 12 mm in thickness, with yield strengths up to 1200 MPa—a critical requirement for sectors emphasizing strength, durability, and weight reduction.

By utilizing advanced flattening and stress-relief technologies, the company ensures:

• Flatness under 5 mm

• Deformation-free cutting

• Straightness maintained post-processing

This level of performance has been particularly impactful for customers working with ultra-high-strength steels, which are known for their springback and challenging cutting properties. Jingjiang Daming’s precision processes help customers overcome these technical challenges while reducing downstream adjustments and improving assembly efficiency.

Commitment to Quality and Innovation

Jingjiang Daming’s strong results stem from a long-standing focus on process optimization, intelligent manufacturing, and lean production management. These efforts are supported by the company’s extensive inventory of stainless steel, carbon steel, and high-strength materials, as well as its growing investment in automated processing lines and precision machining technologies.

Daming’s approach ensures that every plate processed—whether for structural components, automotive frames, or engineered products—delivers consistent dimensional accuracy, formability, and surface integrity.

In addition to quality, operational flexibility and fast lead times remain key differentiators. With a fully integrated production system and a highly trained technical team, Jingjiang Daming can rapidly adjust output and customize solutions based on specific customer requirements, ensuring timely delivery and optimal cost performance.

Expanding Service Capabilities

Looking ahead, Jingjiang Daming plans to broaden its portfolio with the launch of branded container plate services, further enhancing its ability to provide comprehensive steel solutions across multiple sectors. The company is also accelerating the development of its “one-stop” processing and supply platform, aiming to provide seamless services to both upstream suppliers and downstream manufacturers.

By leveraging the scale and synergy of the Daming Group, Jingjiang Daming is not only strengthening its market position but also actively supporting the transformation and upgrading of China’s broader manufacturing industry.

“These achievements are a result of years of strategic planning, technology investment, and customer collaboration,” said a spokesperson for Jingjiang Daming. “We remain committed to delivering high-performance steel solutions that empower our clients to innovate, reduce costs, and improve product quality. With continued focus on precision, efficiency, and value-added service, we are confident in our ability to lead the next chapter of high-quality development.”
