As a new generation of laser microprocessing equipment, femtosecond laser can effectively prevent surface melting and subsequent structural changes for the processing of medical needles and needles made of most metal materials. If the needle is made of polymer material, it can also avoid potential toxicity and structural damage problems.
Plastic needles are more demanding, often requiring the creation of slots or holes to deliver the drug, and if you want to create a specific gas or drug flow through these tubes, they must be of a highly controllable, repeatable size. After drilling a small hole and applying a specific pressure, the flow height from one tube to another will be controlled. Drilling small holes in microfluidic medical devices is one of the advantages of femtosecond lasers.
With the increasing number of applications where metal parts and instruments need to be connected, laser welding has also become an indispensable step in micro-laser micro-machining processes. Femtosecond laser welding can precisely connect the components or form a sealed structure to avoid leakage or penetration. The high-precision welding capability of femtosecond laser is widely used in electronic 3c, precision medical devices, semiconductor integrated circuits and other industries.
In the process of manufacturing medical devices and electronic 3C products for traceability or quality inspection requirements, it is necessary to identify code marks, and the precision marking process of femtosecond laser will not change the composition and surface shape of the product material, but also ensure that the marking part will not corrod during the sterilization process, nor will it affect its use function. Femtosecond laser marking is likely to become mandatory in the future.
Fiber lasers are different from femtosecond lasers in that they have high power and can achieve faster cutting and thicker plate cutting, while femtosecond lasers for cutting thinner materials can not only reduce the repetition rate but also avoid cumulative heat damage. The specific choice of equipment depends on the processing material and quality requirements and the corresponding application scenario.
