Thin Slab Preprocessing Solution 6 - 12MM

Step 1. Uncoil and automatically feed  

The coiled steel material is fed into the uncoiling system, flattened, and continuously supplied to the laser cutting machine. 

Compared to the method of using pre-cut steel sheets, the uncoiling solution significantly reduces storage area, limits intermediate stacking operations, and optimizes material usage efficiency. Continuous feeding also helps the cutting machine operate more stably, reducing waiting time between production batches.

Step 2. Laser cutting  

After being fed, the material enters the laser cutting machine to process parts according to production drawing data. 

At this stage, a coil of steel can simultaneously create various types of parts such as: Connection plates, stiffening ribs, base plates, component sheets, auxiliary parts of the steel structure. 

The ability to cut accurately and at high speed helps reduce waste, improve part quality, and limit reprocessing stages after cutting.

Step 3. Automatic sorting of parts after cutting  

After completing the cutting stage, the system automatically divides the products into two groups for processing according to geometric characteristics and size. 

Plate-shaped parts group: These parts are automatically picked up directly from the cutting table and transferred to the conveyor system. Automating this stage helps eliminate manual collection operations, reduces the risk of part deformation, and maintains continuous production rhythm for the laser cutting machine. 

Flange and Gusset Plate-shaped parts group 

Due to the large quantity and small size, a specialized gripping robot will automatically recognize and pick up parts after cutting. This solution helps eliminate the manual task of picking up plates, which is labor-intensive and prone to errors during sorting.

Step 4. Automatic transportation  

For plate-shaped parts, the material is transported by the conveyor system. For flange and small parts, AGV is responsible for transportation between areas in the factory. As a result, the material flow is maintained continuously, reducing the need for forklifts and limiting bottlenecks in the production process.

Step 5. Laser engraving and product tracking

Before warehousing, parts are laser engraved to store identification information such as: 

• Product code.  
• Part code.  
• Order code.  
• QR code for tracking.  

This information helps reduce material search time, supports production control, and creates a foundation for data management throughout the entire line.

Step 6. Storage and ready for assembly stage

After being sorted and identified, parts are transferred to the raw material warehouse. From here, materials can be directly supplied to beam assembly lines, welding robots, or subsequent production stages without needing to re-sort manually. 

The result is a significant reduction in production preparation time, minimizing part loss, and improving material management efficiency throughout the factory.
