High Density Cast Iron D28 3D Welding Table Industrial Grade Quality
High Density Cast Iron D28 3D Welding Table Industrial Grade Quality It is a modular flexible welding platform with heavy load, high precision, and long service life. The core is made of high-density gray cast iron (HT250/HT300), specially designed for long-term industrial welding scenarios such as heavy steel structures, engineering machinery, ships, and energy equipment. It focuses on super rigidity, deformation resistance, high wear resistance, and long-lasting precision.
The elastic modulus of high-density cast iron is ≥ 110GPa, which is 20% higher than that of ordinary cast iron, and the deflection under heavy load is ≤ 0.03mm/m.
Overall stress relief annealing eliminates internal stresses in casting, ensuring long-term use without deformation and accuracy degradation.
Cast iron has a low coefficient of thermal expansion (10-12 × 10 ⁻⁶/℃), with minimal thermal deformation at high welding temperatures, ensuring welding accuracy.
Excellent vibration reduction and stability
The vibration reduction performance of cast iron is 5-8 times that of steel, absorbing welding vibration, reducing weld stress and deformation, and improving welding quality.
High density materials have extremely high stability, with a 10-year precision drift of ≤ 0.05mm/m, suitable for batch precision welding.
Long lifespan and low maintenance
Nitriding surface is wear-resistant, rust proof, and slag resistant, and does not require frequent oil maintenance. Daily cleaning is only necessary.
The main body has a lifespan of 10-15 years, which is 2-3 times that of ordinary steel welding stations, and the long-term use cost is lower.
Typical application scenarios
Heavy duty steel structures: building steel structures, bridge components, engineering machinery frames/arms, mining machinery parts.
Ship and marine engineering: welding of hull segments, offshore platform components, pressure vessels and pipelines.
Energy equipment: wind turbine towers, photovoltaic brackets, boilers/heat exchangers, nuclear power equipment components.
Multiple varieties and small batches: replacing specialized fixtures, fast production change, reducing tooling costs by over 70%, suitable for flexible production lines.
Industrial grade quality assurance
Manufacturing standard: High Density Cast Iron D28 3D Welding Table Industrial Grade Quality follows JB/T7974-99 Cast Iron Platform Standard, CE, ISO 9001 certification.
Material testing: Provide material reports, hardness testing, and accuracy testing reports to ensure industrial grade quality.
Packaging and transportation: rust proof film+pearl cotton+wooden pallet+steel strip, IPPC fumigation, suitable for sea/land transportation.
Installation and after-sales service: 10 minute quick leveling, providing 1-year warranty and lifetime maintenance service.
