Metal corrosion processing refers to the use of chemical reactions or physical impacts to create concave-convex or hollow effects on metal materials. Corrosion processing involves removing the photosensitive ink from the areas that need to be corroded after exposure plate development, connecting the chemical solution to the corrosion equipment to achieve the effect of metal corrosion, and forming concave-convex lines.
Laser processing uses lasers to instantaneously melt and vaporize metals for physical modification to achieve metal processing. Laser engraving on metal results in smooth surfaces, clear lettering, and minimal wear and tear.
Both of these processing methods can create hollows, engravings, and concave-convex patterns on metals. However, due to differences in processing methods, specific distinctions are as follows:
The difference between etching technology and cutting processing lies in the fact that etching technology does not produce waste residue as laser cutting does. Additionally,precision metal etching can change the shape of materials without altering their properties, unlike laser cutting, which creates a considerable width of heat-affected zone at the part edges.
Etching can change the shape of materials without altering their properties, while laser cutting differs in that it creates a considerable width of heat-affected zone at the part edges.
Etching can simplify the processing of complex components. For instance, if there are too many mesh holes to remake, it’s not cost-effective to use other processing methods. With etching, thousands of mesh holes can be processed simultaneously. Considering laser technology for processing, one can imagine how much time it would take.
Furthermore, laser cutting can result in:
- Melting points and burrs at the bottom
- Local overheating
- Overheating at interfaces
- Hard burrs at edges
- Local hard burrs
- Soft burrs at edges
Regardless of process or cost, etching remains highly favorable.
Differences in etching, stamping, and laser cutting for metal speaker grille processing:
Metal speaker grille processing commonly involves the following three methods:
Stamping is common for processing metal speaker grilles, especially for those with rough appearance requirements and less stringent requirements for mesh holes. It’s suitable for metal speaker grilles with large mesh holes, wide spacing, and many mesh holes.
Advantages: Low processing cost, fast speed, simple personnel arrangement.
Disadvantages: High mold costs, mesh holes have burrs and roll edges, prone to deformation, not conducive to updating new products, high research and development costs.
The application of laser cutting for metal speaker grilles is not yet widespread. Although it produces perpendicular hole walls, it also has many shortcomings.
Advantages: Can cut very small and dense mesh holes, perpendicular hole walls.
Disadvantages: Burrs at mesh edges, residue around mesh holes after cutting, change in material properties, blackening and residual scorching at edges.
Etching processing of metal speaker grilles avoids the drawbacks of stamping and laser cutting. It can process stainless steel and other metal speaker grilles with thicknesses between 0.01mm and 2mm. The mesh holes of the speaker grille are uniform, without burrs, roll edges, and with perpendicular hole walls.
Advantages: Smooth holes, no burrs, flat and uniform surface, convenient for design changes, low cost.
Disadvantages: Relatively higher cost for mass production compared to stamping, much lower cost compared to laser cutting.
Etching and laser processing are two different processing methods, each with its own roles and applications. Next, let’s delve into the differences between etching and laser processing.
Different processing materials
Etching is typically used for processing metal materials, while laser processing is typically used for non-metal materials. Etching can be used for various metal materials, including copper, aluminum, stainless steel, etc., while laser processing is only suitable for certain types of metal materials.
Different processing depths
Etching can achieve greater processing depths compared to laser processing. The processing depth of etching usually depends on the material, process, and equipment performance, while the processing depth of laser processing depends on the material type and laser power.
Different processing ranges
The processing range of etching is relatively wide compared to laser processing. Etching can expand its processing range through different processes, while the processing range of laser processing typically depends on the type of laser and processing equipment.
Different processing speeds
Etching generally has a slower processing speed compared to laser processing. The processing speed of etching usually depends on the process, equipment, and technician experience, while the processing speed of laser processing typically depends on the type of laser and processing equipment.
In conclusion, etching and laser processing are both crucial tools in modern manufacturing technology, each with its own unique applications. When choosing a processing method, it’s essential to consider the product requirements and material types to select the appropriate method.
