Femtosecond lasers and high-performance piezo valve nozzles: the perfect combination for precision machining

A piezoelectric valve nozzle is a nozzle device that uses the piezoelectric effect to control fluid flow. The piezoelectric effect is the deformation of certain materials when subjected to an external electric field and vice versa. In piezoelectric valve nozzles, materials such as piezoelectric ceramics are often used, and these materials can be deformed slightly when an electric field is applied to them, thus changing the state of opening and closing of the fluid passage of the nozzle.

Piezo valve nozzles work by controlling the opening and closing of the fluid passage by controlling an external electric field. When an electric field is applied, the piezoelectric material deforms, causing the nozzle channel to open and the fluid to pass through; conversely, when the electric field disappears, the piezoelectric material returns to its original state, the nozzle channel closes, and the fluid stops flowing.

Piezoelectric valve nozzles have the advantages of fast response, precise control and low power consumption, so they are widely used in the fields of microfluidic control, precision liquid distribution, medical devices and chemical experiments. For example, in the biomedical field, piezoelectric valve nozzles can be used to accurately control the release amount of medicinal fluids to achieve precise drug delivery; in the laboratory, they can be used for operations such as micro-liquid dispensing and mixing.

Femtosecond laser processing plays an important role in the manufacture of piezoelectric valve nozzles. Its high precision and non-thermal processing characteristics make it one of the ideal processes for manufacturing high-performance piezoelectric valve nozzles.

Firstly, femtosecond laser processing can accurately cut and machine piezoelectric materials, such as piezoelectric ceramics, on a micron scale. This precision ensures that the size and shape of the nozzle channel meets design requirements, guaranteeing precise control of the fluid.

Secondly, femtosecond laser processing has a very small heat-affected zone, which means that there is virtually no thermal damage or distortion of the surrounding material during processing. For temperature-sensitive materials such as piezoelectrics, this is critical to keep the original properties and characteristics of the material intact.

In addition, femtosecond laser processing offers a high degree of flexibility, allowing complex structures and shapes to be realised. For piezoelectric valve nozzles, this means that more efficient and precise fluid channel structures can be designed, improving nozzle performance and stability.

Femtosecond laser processing offers an efficient, precise and controlled processing method for the manufacture of piezo valve nozzles, helping to realise high-performance and highly reliable piezo valve nozzle products. The application of femtosecond laser processing in microfluidics, medical devices, laboratory equipment and other fields will bring new opportunities and challenges for the development of piezoelectric valve nozzles.
