Product Name: D28 Position Pins / Locating Pins for Modular Welding Tables
Series: D28
Compatible System: 3D Flexible Welding Fixture System
We are always at your service when you need
D28 Position Pins are precision-engineered locating components designed specifically for D28 series 3D modular welding tables and fixture systems. These pins are inserted into the Φ28mm precision bores (spaced at 100mm × 100mm grids) to accurately position, align, and secure workpieces, fixture elements, and table extensions.
As a fundamental component of any modular fixturing setup, position pins enable rapid, repeatable, and highly accurate workpiece positioning without permanent tack welding or custom tooling .

Core technology
The positioning system is used to accurately adjust and fix the workpiece to ensure accurate welding position.
The clamping system is used to secure the workpiece and prevent thermal deformation or vibration during welding.
Modular fixture system: standardized grid (such as 28mm or 16mm hole spacing) is used to achieve flexible positioning.
T-slot or grid hole workbench: the surface is equipped with precision machining holes or slots for installing fixtures, locating pins and other accessories.Adjustable support arm/stick: suitable for multi-angle positioning to meet complex welding requirements.
Rotating/tilting worktable: used for 360 welding (common in robotic welding).
Manual fixtures: such as quick release Clamps, C-type clamp, spiral clamp, etc., suitable for simple welding tasks.
Pneumatic/hydraulic fixture: automatic clamping, suitable for mass production.
Magnetic fixture: used for ferromagnetic materials (such as steel parts), can be quickly positioned.
Vacuum fixture: suitable for aluminum, copper and other non-magnetic materials.
product advantages
Repeatability: Suitable for mass production to ensure welding consistency.
Improve efficiency: faster and more accurate than traditional fixed methods.
Reduced deformation: firm clamping can reduce the deformation caused by welding thermal stress.
Application Range
Workpiece Positioning: Accurately locating components on welding tables prior to clamping and welding.
Fixture Assembly: Connecting and aligning modular fixture elements (angle blocks, support blocks, V-blocks) to the table.
Table Splicing: Joining multiple welding tables together to create larger working surfaces without gaps or steps.
Robotic Welding Cells: Providing repeatable workpiece positioning for automated welding operations.
Heavy Fabrication: Securing large steel structures, construction machinery components, and heavy frames.
Precision Assembly: Serving as alignment pins for assembly jigs and inspection fixtures.

FAQ
tIPS FOR REFERENCE
Answering the following questions can roughly help you understand our products.
Q:1.What does "D28" mean?
A:D28 refers to the 28mm diameter of the positioning pin and the corresponding mounting holes on the welding table. D28 pins are designed for heavy-duty applications on tables with 100mm × 100mm hole spacing. For light/medium duty, D16 series (Φ16mm holes, 50mm spacing) is available
Q:2.Are D28 position pins compatible with all welding tables?
A: No. D28 pins are specifically designed for D28 series welding tables featuring Φ28mm precision bores on a 100mm × 100mm grid pattern. They are NOT compatible with D16 series tables (Φ16mm holes)
Q:3.Can I use these pins for table splicing?
A: Yes. Positioning pins are commonly used to align and connect multiple welding tables together, ensuring seamless, gap-free assembly of larger working surfaces
Q:4.What is the positioning accuracy?
A: D28 systems achieve ±0.05mm positioning accuracy (X/Y/Z axes) and flatness of ≤0.1mm/m² when used with quality welding tables
Q:5.Are the pins rust-resistant?
A: High-quality D28 position pins feature nitrided surface treatment, which provides excellent corrosion resistance and protection against welding spatter adhesion
Q:6.What is the lead time?
A:Standard 25mm thickness usually 5-10 days. Custom thickness or special hole patterns require 15-20 days.
