How to Choose a Cost-Effective 3D  Welding Table

1. Choose a Well-Known Brand Manufacturer: Reputable brands strictly control product quality and avoid unhealthy price competition.

2. Check Product Material: Regular foundries provide strict material reports and casting quality assurance.

3. Genuine HT300 Material: Ensures uniform surface and good molten iron fluidity.

4. Manufacturer Selection: Reputable brands choose quality foundries, ensuring sufficient panel thickness, multiple reinforcement ribs, no casting pores, and strict heat treatment to eliminate internal stress. Surface is shot peened and primed.

5. Tolerance parameters

   □ L x W x H (mm): L±0.1 ,W±0.1,H±0.1      ○ Hole: ∅28D10（+0.149/+0.065

  □  Flatness: 0.1/1000 (mm)                         ∥ Parallelism:  0.1/1000 (mm), 

  ⊥ Verticality: 0.1/200 (mm)                        ≒ Finished plate thickness:23-24.5 (mm)

6. Avoid Inferior Goods: Genuine platforms without casting pores show no signs of repair welding. Discoloration indicates repair.

7. Table Weight: Generally, heavier platforms of the same specification are better, indicating sufficient material use and quality assurance. Genuine 3D fixture platforms have a reasonable weight according to 3D design principles.

 How to Distinguish the Quality of a 3D Table

- Appearance Quality: Surface roughness, defects, dimensional errors, shape errors, insufficient panel thickness, and the presence of casting pores are critical quality indicators.

- Dimensional Measurement:

    - 3D Dimensions (Length, Width, Height)

    - Surface Finish (≤1.6)

    - □ L x W x H (mm): L±0.1 ,W±0.1,H±0.1 ,○ Hole: ∅28D10（+0.149/+0.065□  Flatness: 0.1/1000 (mm) ,∥ Parallelism:  0.1/1000 (mm), ⊥ Verticality: 0.1/200 (mm)

- Material Report: Availability of material reports (High strength steel, HT300 cast iron, SUS304 stainless steel) and information on welding and heat treatment processes.

Indicators of Inferior 3D Flexible Cast Iron Fixture Platforms:

1. Low-Grade Cast Iron: Dark gray surface, use of HT100-150 inferior materials, mainly clay and iron slag.

2. Insufficient Panel Thickness: Uneven thickness, few and thin reinforcement ribs, rough and unclean.

3. Poor Surface Wear Resistance: Numerous casting pores, prone to oxidation and corrosion, obvious repair welding marks.

4. Lack of Heat Treatment: Quick deformation and easy breakage, poor processing accuracy.

5. Incomplete Surface Treatment**: Non-working surfaces not shot peened and simply painted, resulting in easy paint peeling.

 Key Technical Parameters and Material Properties of 3D Cast Iron Platforms:

- Material: High-quality HT300, subjected to strict artificial aging and 180 days natural aging.

- Advantages: High strength, good wear resistance, resistance to fracture and bending, non-stick welding slag.

- Accuracy:

    - Flatness: 0.1mm/m²

    - Verticality: 0.1mm/m

    - Hole Spacing Tolerance: ≤0.05mm

    - Hole Diameter Tolerance: ±0.05mm

- HT300 Material Properties: Pearlitic gray cast iron with a minimum tensile strength of 300MPa, high strength, good wear resistance, suitable for high bending stress applications requiring high air tightness.

Applications:

These high-quality 3D Table are widely used in automotive manufacturing, construction machinery, steel structure production, sheet metal frame processing, motorcycle manufacturing, and with welding robots or special welding machines.
