Precise Micro-perforation on Glass Microneedles with MOPA Laser Marking Machine

In the realm of precision manufacturing, the MOPA (Master Oscillator Power Amplifier) laser marking machine stands out for its versatility and precision in various applications, including the creation of micro-features on delicate materials such as glass microneedles. The ability to create 30 µm ejection holes on these microneedles is a testament to the advanced capabilities of MOPA laser technology.

Introduction to MOPA Laser Marking Machine:

The MOPA laser marking machine is renowned for its high-resolution marking and the ability to control pulse width and frequency independently. This level of control is crucial for applications requiring intricate details and precision, such as the creation of micro-perforation on glass microneedles. The machine's non-contact marking process ensures that the integrity of the glass microneedles is maintained, avoiding any physical deformation that could occur with traditional mechanical methods.

Key Features of MOPA Laser Marking Machine:

1. High Precision: The MOPA laser system offers superior beam quality and stability, which is essential for creating precise micro-holes as small as 30 µm without causing any damage to the surrounding material.

2. Independent Pulse Control: The ability to independently adjust the pulse width and frequency allows for fine-tuning the laser's interaction with the glass, ensuring the creation of clean, crisp holes without any heat-affected zones or cracks.

3. Non-Contact Process: The non-contact nature of laser marking eliminates the risk of mechanical stress or breakage, which is particularly important when working with fragile materials like glass microneedles.

4. Speed and Efficiency: MOPA lasers can perform high-speed marking, which is beneficial for mass production of microneedles with consistent quality.

Application in Glass Microneedles:

Glass microneedles are used in various medical and scientific applications, such as drug delivery and fluid sampling. The creation of 30 µm ejection holes is critical for the functionality of these devices, as they must allow for the precise flow of substances.

Process of Creating 30 µm Ejection Holes:

1. Material Analysis: Before marking, the MOPA laser system analyzes the glass microneedle to determine the optimal parameters for creating the ejection holes without causing裂边 or other damage.

2. Laser Parameter Settings: The operator sets the laser parameters, including the pulse width, frequency, and power, to achieve the desired hole size and depth.

3. Marking Process: The MOPA laser marking machine then focuses the laser beam onto the precise location on the microneedle, creating the 30 µm ejection hole through a series of controlled pulses.

4. Quality Control: After the marking process, the microneedles are inspected to ensure that the ejection holes are accurately placed and properly formed, with no裂边 or other defects.

Conclusion:

The MOPA laser marking machine's ability to create 30 µm ejection holes on glass microneedles without裂边 showcases its precision and control in micro-manufacturing applications. This technology is a valuable asset in industries where high precision and quality are paramount, such as medical devices and scientific instruments. As technology continues to advance, the MOPA laser marking machine will likely play an even more significant role in enabling the creation of complex and delicate micro-features in various materials.
