The D16 Modular Welding Table with 3D Fixturing Capability System is a lightweight, high-precision 3D flexible welding fixture platform. Centered on the Φ16mm standard positioning hole system and 50×50mm dense grid layout, it features a five-sided working surface (top + four sides) that enables 360° three-dimensional clamping and positioning of workpieces in the X/Y/Z axes.

With a full set of standardized modular accessories, it eliminates the need for custom jigs for each product, making it ideal for multi-variety, small-batch production and sample prototyping. Whether you're working on sheet metal frames, medical equipment parts, new energy battery brackets, or small automotive components, this system delivers consistent accuracy, fast setup times, and long-term durability—all while reducing production costs and workshop space usage.

The D16 system is the precision, lightweight variant among the three mainstream 3D welding table systems (D16, D22, and D28), designed as a counterpart to the heavy-duty D28 system:

• Positioning hole diameter: Φ16mm (tolerance: +0.05 to +0.12mm); compatible with standard M16 quick-locking pins and fixtures
• Grid spacing: 50mm × 50mm; overall hole-to-hole spacing tolerance: ±0.05mm
• Five-sided hole layout: The tabletop features a full grid pattern, while each of the four side panels has three horizontal rows of D16 positioning holes, allowing tooling to extend downwards or outwards for 3D clamping
• Tabletop markings: Laser-engraved millimeter coordinate scales on the X and Y axes, eliminating the need for repeated manual marking to establish reference points
• Precision specifications: Tabletop flatness ≤0.1mm/1000mm; perpendicularity between tabletop and side panels ≤0.1mm/200mm; resistant to deformation during long-term welding operations

• Full 5-sided 3D clamping structure, clamp workpieces from X/Y/Z axes for complex irregular parts
• Φ16mm 50×50mm dense hole grid, ultra-precise positioning for small & thin metal components
• Lightweight modular fixtures, one worker completes assembly and disassembly quickly
• All accessories reusable, no custom jigs needed, slash jig manufacturing costs greatly
• Fast changeover, only 10-30 mins to rebuild fixture for new products
• Gas nitrided worktop, anti-weld spatter, rust-proof and long service life
• Dual material options: Q355 steel for cost efficiency, HT300 cast iron for robotic high precision
• Multi-purpose platform for welding, assembling, inspecting and drilling
• Multiple sizes available, tables can be spliced freely for extra-large workpieces
• Lower initial investment than D28 heavy tables, perfect choice for SMEs & prototype workshops

• Tabletop unit: 12-month warranty; free repair or replacement for flatness deformation or machining defects (excluding damage caused by human-induced impact or overloading)
• Fixtures, locating pins, and supports: 6-month warranty; low-cost replacements available for wear and tear from normal use
• Stands, casters, and lifting mechanisms: 1-year warranty; wear parts available separately

• Remote video guidance for installation and fixture setup
• Provision of CAD layout plans for workpieces and fixtures; complimentary design of clamping strategies
• On-site calibration and training services available for overseas customers upon request
• Long-term, stable supply of a full range of replacement parts; no risk of production discontinuation or stock shortages
