D16 and D28 Professional 3D Welding Tables refer to modular three-dimensional welding jig systems built upon standardized grid hole patterns with diameters of 16mm or 28mm. These two hole diameter standards represent the two major mainstream systems in the global modular tooling field, and they represent not merely simple differences in hole size, but rather systematic solutions with different levels of precision, load capacity, and application ecosystems.

• Omnidirectional Flexible Positioning: The table surface and the four surrounding sides provide a total of 5 working surfaces with a regular hole pattern, allowing for multi-directional clamping and positioning along the X/Y/Z axes. This adapts to various complex workpieces without the need for custom fixtures.
• High Precision and Consistency: CNC precision machining, combined with positioning accessories, achieves a repeatable positioning accuracy of ±0.05mm, significantly reducing welding deformation and assembly errors, and minimizing rework.
• Efficient Operation: Quick-release clamps and modular accessories (positioning blocks, connecting blocks, support angles, etc.) allow for rapid switching, reducing clamping time by more than 60% compared to traditional fixtures, and are suitable for single-piece, small-batch, and mass production.
• Durable and Stable: Primarily constructed from high-strength cast iron or Q355 steel, and treated with aging/nitriding processes, it offers resistance to deformation and impact, making it suitable for long-term heavy-duty welding operations.

• Core components: Work surface (with grid holes / T-slots), support frame, clamping system (quick clamps, pressure plates, locating pins, etc.), side positioning surfaces; optional features include casters, height adjustment, and rotation/tilting mechanisms.
• Typical applications: Construction machinery, automotive parts, steel structures, metal processing, shipbuilding, etc.; D16 is suitable for small precision parts (such as automotive chassis parts), and D28 is suitable for heavy structures (such as construction machinery frames).

• The main equipment has a 2-year warranty, and wear parts have a 1-year warranty.
• Common spare parts are available in stock domestically and can be shipped with the complete machine or separately via sea freight, arriving at the port in 25-35 days.
• Lifetime free technical consultation and support for operation/calibration questions are available at any time.
