D28 Nitrided Table for 3000x2000mm Heavy Factory Production

D28 Nitrided Table for 3000x2000mm Heavy Factory Production

The D28 Nitrided Table for 3000x2000mm Heavy Factory Production is a large-sized 3D welding table specifically designed for heavy-duty, large-scale production in industrial factories. It integrates three core features: the D28 heavy-duty hole system, plasma nitriding surface treatment, and a large 3000×2000mm work surface. Its main advantages are large working space, high load capacity, strong durability, and precise positioning, making it suitable for multi-station collaboration, large-scale batch welding, and high-frequency continuous production in heavy-duty factories.

Core structure and material process standards

• Tabletop Base Material: Made of European standard S355 steel, replacing ordinary carbon steel, with a tensile strength of ≥510MPa, and a heat deformation resistance increased by more than 60%. The 3000×2000mm large tabletop is seamless, avoiding fatigue cracking of welded joints during mass production, and is suitable for long-term heavy workpiece loading and high-frequency welding at high temperatures;
• Surface Treatment: Vacuum plasma overall nitriding treatment. After treatment, the surface hardness reaches HV550-HV700, and the nitriding layer depth is 0.3-0.5mm. This prevents high-temperature adhesion of welding slag, resists high-current arc erosion and workpiece impact wear, and also provides rust and corrosion resistance. It is suitable for dusty and high-humidity production environments in heavy-duty factories, eliminating the need for frequent grinding and maintenance;
• Support Structure: Made of 100×100mm thick-walled square steel (wall thickness ≥4mm) welded together, with double-layer reinforcing ribs added. It undergoes pickling and phosphating + electrostatic powder coating treatment (powder coating layer thickness 80-100μm). The bottom is thickened by welding to improve overall support rigidity and prevent sagging and shaking of the 3000×2000mm large tabletop due to dispersed center of gravity;
• Connecting Parts: All fixing bolts are high-strength flange bolts of grade 8.8 or higher, with anti-loosening adhesive coating, preventing bolt loosening caused by welding vibrations during continuous factory production, ensuring long-term equipment accuracy and stability.

Our advantages

• Maximized Production Efficiency: 3000×2000mm large work surface, 4-6 people working collaboratively, daily production of heavy workpieces ≥50 pieces, production capacity increased by 100%+ compared to smaller tables;
• Significant Cost Reduction: D28 international standard hole system, no need for customized tooling, tooling costs reduced by 70%, changeover time ≤20 minutes, suitable for multi-variety mass production;
• Industrial-Grade Durability: Overall plasma nitriding, HV550-HV700 hardness, 24-hour continuous mass production without wear, maintenance costs only 1/5 of ordinary tables;
