Differences between D28 and D16 series

As core sub-products of 3D flexible welding equipment, the D28 and D16 series are precisely positioned for different application scenarios, forming a complementary balance between "heavy-duty and robust" and "precision and flexibility." This completely breaks through the industry pain points of traditional specialized tooling, such as limited adaptability, inefficient production changes, and high costs. It can meet the welding needs of all scenarios, from small precision parts to large structural components, and is suitable for multi-variety, small-batch production models.

The D28 series focuses on heavy-duty efficiency and is specifically designed for heavy-duty scenarios such as large steel structures and heavy machinery. This series is integrally formed using HT300 cast iron or Q345 high-strength steel. The table surface undergoes precision machining and nitriding treatment, resulting in high hardness and strong wear resistance, effectively resisting welding spatter corrosion and extending the equipment's service life.

• Core: standardized Φ28mm hole system, with the hole spacing arranged in an array of 100mm±0.05mm.
• Table and four sides are all distributed with grid holes, and the side holes can further expand the clamping area.
• Maximum load can reach more than 10 tons.
• Hole system positioning accuracy is stable within ±0.05mm.
• Effectively ensures the dimensional accuracy and geometric tolerance of large welded parts.
• Widely applicable to heavy-duty scenarios such as shipbuilding, rail transportation, and construction machinery.
• Can meet the production needs of large enterprises such as XCMG and Sany Heavy Industry.

Complementing the heavy-duty positioning of the D28 series, the D16 series focuses on precision and flexibility, targeting welding scenarios for small, precision parts. This series features Φ16mm holes arranged in an array with a spacing of 50mm ± 0.05mm, and a 50x50mm grid on the table surface, facilitating visual inspection and precise positioning of the workpiece.

• Lighter design maintains the same positioning accuracy of ±0.05mm.
• Flexibly adapts to the welding needs of small, precision workpieces such as sheet metal parts, small steel structures, 3C electronic components, and medical device parts.
• Utilizing a dense hole design and modular components, this series allows for rapid tooling assembly.
• Completing new product tooling configuration within minutes to hours, significantly shortening tooling preparation time.
• Reduces investment in dedicated tooling and storage costs, balancing economy and practicality.

Both product series retain the core advantages of the 3D flexible welding station, employing a standardized, modular component design. Like building blocks, components such as positioning pins, clamps, and square boxes can be flexibly combined according to the shape and size of the workpiece, eliminating the need to remanufacture dedicated fixtures.

• Allows one set of equipment to adapt to the production of multiple products, significantly improving production flexibility and changeover efficiency.
• Products can be integrated with CAD/CAM/PLM systems to achieve virtual design and simulation verification of tooling, driving the digital and standardized transformation of welding production.
• Well-organized modular structure also reduces the risk of collisions during welding operations, improving operational safety.
• Stable positioning and clamping reduce welding deformation and errors, improving weld quality and lowering rework rates.
