High Precision Cast Iron Steel Nitriding D28 2D 3D Welding Table

The High Precision Cast Iron Steel Nitriding D28 2D 3D Welding Table is a high-precision, modular, and nitrided cast iron/cast steel welding workbench with a D28 hole pattern. It supports both 2D planar and 3D spatial clamping and welding, making it a core piece of flexible precision welding equipment for industries such as sheet metal fabrication, engineering machinery, automotive, and aerospace. Unlike ordinary welding tables, it emphasizes high rigidity, high precision, long service life, and strong compatibility.

1. High Precision + High Rigidity
   Cast iron/cast steel material + reinforced rib design provides resistance to deformation and vibration absorption, ensuring workpiece stability during welding and guaranteeing weld consistency and dimensional accuracy.
   Nitriding treatment + precision milled holes ensure that the hole positions remain unchanged and free from wear even after long-term use, maintaining accuracy for over 10 years (compared to ordinary powder-coated tables which lose accuracy in 1-2 years).
2. 2D/3D Dual-Mode Versatility, Extremely Flexible
   2D mode: Flat welding, assembly, marking, and inspection – a multi-purpose machine that reduces equipment investment.
   3D mode: 5-sided hole pattern + modular fixtures allow for vertical, inclined, and inverted clamping. Complex structural parts do not require custom tooling, reducing changeover time from hours to minutes.
3. Long Lifespan + Low Maintenance
   The nitrided surface resists welding slag, high temperatures, and corrosion. Welding slag is easy to clean, eliminating the need for frequent grinding/repainting.
   The cast iron/cast steel material is resistant to cracking and deformation, resulting in maintenance costs that are only 1/3 of those for ordinary welding tables.
4. Strong Compatibility + Expandability
   The D28 hole system is an industry standard, compatible with mainstream global brands of fixtures, requiring no additional adaptation.
   Supports unlimited splicing, with an overall flatness of ≤0.3mm/m² after splicing, allowing for the creation of flexible welding production lines; can be equipped with modules such as rotary platforms, hydraulic lifting, and welding fume purification to expand functionality.
5. Safety + Environmental Protection
   The table surface provides even load distribution, ensuring safe clamping of heavy workpieces; the nitrided surface contains no harmful substances and produces no odor during welding; when combined with a welding fume purifier, it meets environmental protection requirements.

The High Precision Cast Iron Steel Nitriding D28 2D 3D Welding Table is heavy equipment (each unit of the 1000×1000mm model weighs approximately 500kg). Collision prevention and deformation prevention are critical aspects of packaging and transportation. We have developed customized solutions for different transportation methods to reduce the damage rate to below 0.5%:

1. Standard Sea Freight Packaging: The tabletop is wrapped with three layers of thickened waterproof film, pearl cotton, and bubble wrap. Hard plastic corner protectors are added to the edges (to prevent bumps). The base is secured with steel straps, and the entire unit is placed in a solid wood fumigated crate (with IPPC marking). Internal bracing is added to the crate to prevent movement during transportation.
2. Air Freight/Express Delivery Packaging: For smaller sizes (such as 800×800mm), a custom-made fully enclosed solid wood crate is used. EVA foam is added inside for precise positioning and a snug fit to the tabletop, preventing accuracy deviations caused by slight vibrations during long-distance transportation.
3. Bulk Container Packaging: For multiple units of the modular type, a layered arrangement with overall securing is used. Thick wooden boards are used to separate the tabletops, and forklift slots are used at the bottom for securing. This maximizes container space utilization and reduces unit transportation costs.

• Q1: What are the differences between the D28 and D16 welding tables?
  A: The D28 has a 28mm hole diameter and a 100×100mm hole spacing, with a higher load capacity (5-20 tons/m²), suitable for heavy/large workpieces; the D16 has a 16mm hole diameter and a 50×50mm hole spacing, with a lower load capacity (1-3 tons/m²), suitable for small/precision workpieces. The clamps are not interchangeable between the two, and the D28 has greater compatibility.
• Q2: Can 2D and 3D welding tables be converted into each other?
  A: A 3D table can be used directly as a 2D table (using only the top surface); a 2D table cannot be directly converted into a 3D table (no side hole array). If 3D functionality is required, it is recommended to purchase the 3D model directly.
• Q3: Will the nitrided layer peel off?
  A: Under normal use (no impact, no cutting, no strong acid or alkali corrosion), the nitrided layer can remain intact for 5-8 years; if damaged by human factors, it can be returned to the factory for re-nitriding treatment.
• Q4: Can you provide samples?
  A: We can provide a 1000×1000mm standard sample. The sample fee is charged at the original price, and the sample fee will be fully refunded for bulk purchases (XX units or more). Sample shipping costs are borne by the customer.
• Q5: Delivery time and payment methods?
  A: The delivery time for standard models is 7-10 working days, and for customized models, it is 15-20 working days; Payment method: T/T 30% deposit + 70% balance (paid before shipment), customized models require T/T 30% deposit + 70% balance, and long-term customers can negotiate L/C/deferred payment.
