3D Cast Iron Nitrided Welding Table

1. Material Properties
High-Quality Cast Iron: Manufactured from high-strength gray cast iron or ductile iron, it offers excellent vibration damping and thermal stability.

Nitriding Surface Treatment: A nitriding process creates a hardened surface layer, significantly improving wear and corrosion resistance.

Thermal Stability: Cast iron's low coefficient of thermal expansion ensures dimensional stability under varying temperatures.

2. Structural Design
3D Modular: The table's surface and sides are covered with a standard-pitch hole pattern (typically 28mm or 16mm pitch).

Precision Machining: High hole positioning accuracy (typically within ±0.05mm) ensures repeatable positioning accuracy.

Heavy-Duty Construction: A thick tabletop and reinforced ribs provide exceptional rigidity.

3. Surface Treatment
Nitriding: Gas or ion nitriding creates a hardened layer 50-70μm thick on the surface, achieving a hardness of HV800-1100.

Rust-Proofing: The nitrided layer offers excellent rust resistance, suitable for humid or corrosive environments.

Flatness: Precision grinding ensures surface flatness (typically within 0.05mm/m).

4.Advantages
Durability: Nitriding treatment increases surface life by 3-5 times compared to conventional cast iron tables

Versatility: Compatible with a variety of fixtures, positioners, and accessories

Precision Retention: Maintains high accuracy even after long-term use

Economic Benefits: Reduces tooling replacement frequency and reduces long-term costs

Low Thermal Deformation: Suitable for high-temperature welding environments, minimizing the effects of thermal deformation
