Why is Copper Micro Hole Perforated Mesh Better?

What is perforated metal mesh?

Perforated metal mesh is a sheet of metal with a pattern of holes, slots or decorative shapes. It is widely used in various industries due to its versatility, durability and aesthetic appeal. The perforations allow air, light, sound, and liquids to pass through while filtering large particles and retaining strength and structural integrity.

What metals are used in manufacturing perforated metal mesh?

Sheet metal mesh can be manufactured from various metals, including stainless steel, aluminium, carbon steel, brass, copper, titanium and nickel. Each material provides distinct properties, such as corrosion resistance or strength, with the choice of material determined by the specific application requirements.

How is perforated sheet metal mesh manufactured?

Perforated metal mesh sheets are typically produced using traditional machining methods like stamping, laser cutting and water jet cutting. However, these methods can lead to material distortion, burrs and stresses, affecting component integrity. Laser cutting and water jet cutting, with their high temperatures and use of abrasive materials, can also negatively impact the machining of micro metal meshes. Moreover, these traditional processes often face challenges in achieving precise designs and are limited in the types of metals they can machine effectively.

How chemical etching enhances perforated micro metal mesh manufacture

Unlike traditional sheet metal machining methods, chemical etching preserves the properties of sheet metal meshes and eliminates the risk of material distortion. By selectively dissolving material using chemical etchants, this process ensures optimal part performance and overcomes the inherent challenges associated with conventional methods.

Economic cost

Photochemical etching is an economical manufacturing technique that replaces traditional hard tooling with digitally produced photo tooling. Acting as stencils, these tools can swiftly and precisely transfer complex CAD designs onto sheet metal, preparing it for chemical etching at a fixed cost.

Intricate mesh patterns

Chemical etching offers unparalleled design flexibility and complexity. It excels in producing micro metal mesh with extremely fine holes and intricate geometries, achieving openings as small as 0.1mm and consistent pore sizes within +/-0.025mm. These capabilities are often challenging or impractical to achieve using conventional machining methods when cutting holes of varying size on the same part.

High-quality metal mesh

Unlike conventional cutting, chemical etching consistently produces high-quality perforated metal mesh sheets by using chemical etchants to dissolve material from the metal sheet. This process eliminates the physical contact and high temperatures associated with stamping, laser cutting, and water jet cutting, ensuring that all metal mesh components are burr and stress-free, with zero material distortion or degradation.

Scalability

The photochemical etching process offers engineers scalable production capabilities, from prototyping to large-scale manufacturing of perforated metal mesh. By utilising digital tooling and etching all component features simultaneously, this method ensures uniformity, consistency and reduced lead times across production runs.

Main Features of Perforated Sheets

Materials and Benefits

• Perforated metal in carbon steel or pre-galvanized steel: cost-effective and versatile, widely used across industrial sectors.
• Perforated metal in stainless steel: resistant to corrosion.
• Perforated metal in aluminum: lightweight, durable, and non-oxidizing.
• Perforated metal in iron: economically advantageous and easy to work with.
• Perforated metal in copper or brass: for aesthetic or specific applications.

Types of Perforations

Perforated metal can also be produced in various formats to suit different applications:

• Perforated sheet with square mesh: provides greater open area and better visibility.
• Perforated sheet with round holes: the most common and widely used type.
• Custom perforated metal: tailored to meet every need, whether aesthetic or functional.

Dimensions and Thicknesses

Fratelli Mariani perforated metal are available with round and square holes in standard formats (× mm) in stock, and other formats such as × mm upon request. Thicknesses range from 0.3 mm to 10 mm, with hole diameters from 100 mm down to 0.3 mm for micro-perforated metal.
A wide variety of dimensions ensures the use of perforated metal in a broad range of projects, offering versatile and customized solutions.

Open Area Percentage

This indicates the ratio between the surface area of the holes and the total sheet surface. A higher percentage allows for better ventilation or light transmission.

Advantages of Perforated Sheets

1. Weight Reduction The presence of holes reduces the overall weight of the sheet without significantly compromising its mechanical strength, making it ideal for lightweight structures and applications where weight is critical (e.g., in transportation and aerospace).
2. Ventilation and Aeration The holes allow excellent air circulation, making perforated metal suitable for applications like ventilation grilles, industrial filters, and architectural facades that require breathability.
3. Light Transmission Perforated metal filter light, making them useful in decorative, architectural, or industrial contexts to create aesthetic effects, reduce energy consumption, or protect against direct sunlight.
4. Acoustic Properties Perforated metal are used in sound-absorbing panels or acoustic barriers to reduce noise. Combined with sound-absorbing materials, they enhance performance in environments such as tunnels, public buildings, or industrial plants.
5. Mechanical Strength Despite the holes, they retain good structural strength, making them suitable for functional purposes such as fencing, railings, and machinery guards.
