2. Importance of Thickness in Industrial Applications

Understanding the impact of thickness on performance is vital for effective application:

• 1. Durability: Thicker sheets often provide greater strength and resistance to wear and tear.
• 2. Permeability: The thickness can influence the flow rates through the perforations.
• 3. Cost-Efficiency: Investing in the right thickness can prevent frequent replacements and repairs.

3. Recommended Thicknesses for Various Industries

Different industries may require different thicknesses based on their specific use cases:

Construction Industry

For construction applications, sheets between 1.0 mm to 2.0 mm are typically recommended. These sheets provide adequate strength while allowing efficient sound insulation.

Food and Beverage Processing

In food applications, a thickness of 0.5 mm to 1.0 mm is often employed. This is to ensure hygiene and safety while maintaining structural integrity.

Automobile Manufacturing

Automotive industries frequently use thicknesses of 0.8 mm to 1.5 mm, where lightweight materials are equally important as durability.

5. Conclusion

Shortcomings

• High equipment investment Low efficiency of deep holes (hole depth > 5 mm)
• Laser thermal impact (nitrogen protection is required to prevent oxidation when processing stainless steel)

• The hole wall roughness is high (Ra 3.2–6.3 μm) The drill bit is easy to wear and the thin plate is easy to deform.
• Drilling and chip removal: Deep hole processing requires internal cooling drill (to avoid chip blockage)

• High mold cost when quantity is small.
• The aperture is not adjustable and the die is worn out.
• The hole has errors (control method: regular inspection of punch clearance, burr prevention and tolerance reduction).
• Material thickness restrictions.
