How Does Laser Etching Work On Aluminum Parts Surface?
As technology advances, there is an increase in demand for the latest model. Lasers are becoming some of the most commonly used versions for various purposes. We use lasers in reshaping and manufacturing processes. It’s even faster than engraving or annealing procedures. Such an attribute makes it the fastest laser marking method. At Creatingway, we use laser etching work on aluminum. Since it provides a quality surface finish on the material. Below is in-depth information concerning how the process works and helps the industry.
What’s The Laser Etching Process?
A process in which a laser beam creates symbols on a surface is known as laser etching work. We release large quantities of energy levels at given intervals. In doing so, it serves the purpose of cutting and engraving workpieces.
The laser’s extreme heat melts away the surface after contact. The melted metal expands, leaving a mark on the surface. Graphic design software produces laser etching design work. The created designs then help support the vector files. Hence, the graphic module storage is in the form of vector files. Later on, the etching machines pass through some printing purposes. We use CNC machining on the machines to read the vector files. Also, the process helps determine the patterns of the laser movement to make the needed design.
Aluminum Parts Surface Etching
A wide variety of metals use laser etching work. Some examples include; lead, stainless steel, zinc, anodized aluminum, and magnesium. In aluminum etching, it’s widely used in the etching of aluminum.
The etching process dissolves metal precisely and selectively. We use acid etchants or chemicals in the creation of aluminum parts. We are resulting in the making of burr-free and stress-free parts. Workpiece production is more defined, with safety guaranteed.
What’s The Process of Laser Etching?
By pulsing a laser beam, we achieve a high-energy outburst. A release of 100,000 pulses in a pulse laser of 100W. Each of the energy pulsations mounting to 1 millijoule. In engraving the metals, a lesser energy per area is crucial.
During the process, a beam hits the surface of the workpiece. The layer absorbs the beam converting it into heat. Also, it transforms reflected beams of energy into heat. Once the absorption is complete, the surface melts and expands.
The temperature of the workpiece increases with an increase in malleability. As the malleability shifts, the shape also changes. The surface undergoes different formations as it melts and is allowed to cool. Such a process allows permanent high-quality markings on the surface.
What’s The Etching Aluminum Panel Using Simple Steps?
Although we use easy methods in etching aluminum, it involves harmful chemicals. Therefore, necessary precautions are vital before doing the task. Below are some of the materials used in the process;
- A shallow container (to mix peroxide with acid)
- Another container with water (to rinse the panel)
- Hydrochloric acid and hydrogen peroxide
- Aluminum panel
- Some PNP-blue sheets
- Eyeglasses for protection
- Protective clothes
- Laser printer ink
- A design for the etching
The procedure takes place somewhere open and vented. Such an area is free from fumes and deadly gases. All the provided precautions are to ensure personal and the safety of others.
Printing on PNP and Design Creation
The creation of any design takes place in a vector application. It’s vital to flip the model before the printing process. We use a paper sheet material to print the design. Cut along a piece of PNP blue from the edge of the model. Then attach the PNP blue on a sheet and pass it to a laser printer.
Cleaning and Preparing the Aluminum Panel
First, clean and prepare the aluminum panel. Then cut according to the desired choice of want. Once again, remove dirt and clean with water. Let the material dry for some time.
Design Transfer
We transfer the design onto the aluminum panel. It is vital to align the material of the model accurately. Using tape, hold all sides of PNP blue and shield from heat. We protect from the heat by using pieces of cloth on the panel.
Using tape, use an iron to heat the toner covering each side. The transfer is only complete when the whole workpiece turns black. Later, remove the tape and place it on PNP blue.
Laser Etching Work the Aluminum Panel as We Fix the Missing Mark
Use a sharpie pen or paint to fix missing marks. Let the ink coverage be the whole sum, even in the missing areas. Then, we mix acid and peroxide in a plastic container. Upon mixing them in proportions, add hydrogen peroxide, followed by the addition of acid.
The mixture causes a reaction that takes place in the container. Remove the aluminum panel, and clean thoroughly with water.
Paint the Panel
Spray paint the panel and leave it dry. Drying enables a glossy finish appearance on the surface. Sand the surface to remove the extra paint. Rinse the aluminum panel and leave it to dry.
