Is the Quality of Low-Priced 3D Welding Tables Guaranteed? How to Choose?

Is the Quality of Low-Priced 3D  Welding Tables Guaranteed?

Absolutely not! Low-priced tables often lack technical services and sufficient after-sales support.

Are You Looking for Specifications Like:

3000x1500, 2400x1200, 2000x1000, 4000x2000, 2000x2000, 2000x1500, 1500x1500, 1500x1000, 1000x1000, made from HT300 cast iron, high strength steel or SUS304 stainless steel?

How to Distinguish the Quality of 3D Welding table?

When selecting a 3D flexible welding table, consider the following:

◇ Quality Indicators:

1. Appearance: Surface roughness, defects, wall thickness, and the presence of casting pores or sand holes.

2. Dimensions:

   - 3D measurements (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)

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

■ Characteristics of Inferior Cast Iron 3D welding table:

1. Low-Grade Cast Iron: Dull gray surface, using inferior HT100-150 materials (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 and sand holes, prone to oxidation and corrosion, visible repair welding marks.

4. Lack of Heat Treatment: Quickly deforms and easily breaks, poor processing accuracy.

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

■ How to Choose a Cost-Effective Cast Iron 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. Finished Product Inspection:

   - Appearance: Genuine HT300 has a silver-gray surface without casting pores, with many reinforcement ribs on the back, and a smooth, burr-free finish.

   - Dimensional Tolerance: Flatness, verticality of the panel to sides, parallelism between sides should all be ≤0.10mm; hole spacing tolerance ≤0.05mm.

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

7. Platform 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.
