Product Overview
Our OEM HT250
Cast Iron Welding Table is a heavy-duty, high-precision industrial fixture plate designed for professional welding, assembly, inspection, and tooling setup applications. Crafted from premium HT250 gray cast iron with ultra-precision surface grinding, this T-slot fixture plate delivers exceptional dimensional stability, vibration damping performance, and long-term wear resistance.
Fully customizable in size, T-slot specification, and processing requirements, it serves as a universal foundational tool for metal fabrication workshops, automated welding lines, mechanical processing plants, and mold debugging scenarios. Each table undergoes complete stress relief treatment and precision calibration to ensure zero deformation under long-term heavy-load operation.
Core Product Advantages
Premium HT250 Cast Iron Material Performance
Utilizing national standard HT250 gray cast iron with dense pearlite matrix and unique graphite flake structure, this table offers superior industrial adaptability. Features include bending strength above 250MPa, surface hardness of HB170-HB240, excellent compression and impact resistance, and natural graphite self-lubrication that reduces surface friction and extends service life beyond 10 years.
Precision Ground & Stable Dimensional Accuracy
Multi-stage precision grinding technology ensures flatness tolerance within 0.05mm/1000mm, meeting high-precision welding and fixture positioning standards. T-slots are precisely milled with uniform spacing, smooth inner walls, and no burrs for tight fitting with standard clamping fixtures and accessories.
Complete Stress Relief & Anti-Deformation Structure
Dual stress relief treatments including high-temperature annealing and 3-6 months natural aging eliminate internal casting and processing stress. Integral casting with thickened base and reinforced rib structure resists deformation from welding high temperatures, mechanical impact, and long-term static loads.
Universal T-Slot Design & Strong Compatibility
Standard T-slot layout (customizable slot pitch and size) compatible with mainstream welding clamps, positioning pins, pressure plates, bolts, and modular fixture systems. Open T-slot structure supports multi-directional workpiece fixing and flexible positioning for complex welding operations.
Industrial Durability & Easy Maintenance
Cast iron surface provides excellent high-temperature resistance, rust resistance, and scratch resistance. Matte precision grinding surface minimizes welding slag and dust accumulation. Standard load capacity of 2,000kg with heavy-duty custom options available.
