Affordable fiber laser engraver is the best choice for black marking on aluminum oxide and color marking on stainless steel. TechPro provides the best rotary color laser engraving machine.
Color laser engraving machine is a new color laser marking process for creating vibrant and colorful patterns and engravings on metal surfaces. Currently, only MOPA fiber lasers can mark color patterns on metal materials such as stainless steel, chrome, and titanium.
The MOPA (Master Oscillator Power Amplifier) laser is an advanced laser architecture that combines a laser oscillator and amplifier. This design allows the operator more flexible control over the parameters of the laser pulse, giving it the ability to engrave in color.
In the MOPA fiber laser, the pulsed seed optical signal is generated by an electrically driven semiconductor laser chip. The drive electrical signal modulates the output optical signal, enabling precise adjustment of parameters such as pulse width, repetition frequency, pulse waveform and power. This adaptability makes MOPA lasers particularly suitable for complex and high-precision tasks.
One of the outstanding features of the MOPA laser is the adjustable pulse width, ranging from 2 ns to 500 ns. This flexibility allows the operator to optimize the performance of the machine for specific materials and projects. For example, narrower pulse widths minimize the heat-affected zone, which improves processing accuracy and reduces the risk of thermal damage to fragile materials.
MOPA fiber laser markers excel in a variety of applications, including:
Whether you are working with intricate details or sensitive materials, the precision and versatility of MOPA’s laser equipment makes it the right choice for professionals seeking high-quality results.
The principle of color laser engraving is the chemical reaction between the laser energy and the surface of the material, and through the precise control of the reaction process, it achieves to leave a colored mark on the surface of the material. There are three main methods for developing color:
Color output depends on the size of the laser energy density and its thermal effect on the metal material. For example, stainless steel produces a series of color changes in response to an increase in laser energy:
This change is achieved by carefully adjusting the laser parameters (e.g. speed, power and pulse duration) to control the oxide film thickness or chemical change.
Color laser engraving machines, especially those equipped with MOPA fiber laser technology, offer high compatibility for engraving a wide range of materials.The MOPA laser (Master Oscillator Power Amplifier) is a directly modulatable semiconductor laser that can be independently adjusted in terms of pulse width (from 2ns to 500ns) and repetition frequency (up to megahertz), resulting in a stable peak power output.
For metallic materials such as stainless steel, MOPA lasers emit laser light that chemically reacts with them to create oxide layers of varying thicknesses, refracting the light and producing vibrant colors. For softer materials such as plastics, the laser parameters can be adjusted to prevent the material from burning, allowing for precise engraving. For organic materials such as leather or wood, the laser produces crisp, clean marks without damaging the surface.
Users can fine-tune settings to get material-specific results. With a high-speed scanning galvanometer system, it provides excellent accuracy and repeatability, making it the perfect machine for creating intricate, colorful designs on a wide range of materials.
The use of color laser engraving machines has been a transformative force in a wide range of industries, providing unmatched precision and versatility in the surface finishing of workpieces. These machines, especially those utilizing MOPA laser technology, offer a diverse range of capabilities that meet the evolving needs of modern manufacturing, particularly in the electronics, automotive and decorative design sectors. Below are some of the key applications of the machines in various fields:
1. Surface Stripping of Aluminum Oxide Sheets
For the thin, lightweight aluminum oxide housings used in electronics, the MOPA laser excels at removing the anodized layer with minimal thermal distortion. Adjustable short pulse widths ensure clean, precise stripping while maintaining material integrity.
2. Blackening of Anodized Aluminum
The MOPA laser delivers high-contrast black marking (logos, text and model numbers) on anodized aluminum. The adjustable pulse width and frequency allows for crisp black marks and subtle grayscale effects, ideal for branding electronics.
3. Color Laser Marking on Metal
By adjusting the laser parameters, the MOPA laser can produce vibrant colored patterns on metals such as stainless steel and titanium. This is widely used for decorating luxury goods such as watches and customized accessories.
4. Precision Machining in Electronics and Semiconductors
MOPA lasers enable fine scribing and engraving of semiconductors, ITO films and electronic components. The minimal heat-affected zone ensures clean, smooth lines and no material distortion, meeting the stringent requirements of high-precision industries.
From aluminum oxide surface stripping to metal coloring and precision engraving of electronics, MOPA laser equipment offers unmatched accuracy, versatility and control. These attributes make them indispensable tools in the electronics manufacturing process, especially as product designs become increasingly complex and demanding. Color laser engraving is likely to find even wider application in the future as the need for efficiency, quality and customization increases across industries.
