I. Overview of Non-Contact High-Speed Jet Valve Technology
Non-contact high-speed jet valve technology is an advanced manufacturing technology based on the principle of non-contact dispensing. Compared with traditional contact dispensing technology, non-contact high-speed jet valve technology does not rely on surface tension to draw glue from the nozzle, but uses the high fluid momentum generated in the jet valve to quickly inject a certain volume of glue onto the target. This technology eliminates the need for the dispensing valve to move along the Z-axis, avoiding direct contact with the workpiece, thereby improving dispensing accuracy and speed.
Non-contact high-speed jet valve technology can be divided into pneumatic drive jetting technology and piezoelectric jetting drive technology according to different drive methods. Pneumatically driven jet valves use pressure changes to generate jetting force and are suitable for a variety of fluid materials. Piezoelectrically driven valves use the inverse piezoelectric effect of piezoelectric ceramics to achieve high-speed and high-precision dispensing by precisely controlling voltage changes.
II. Latest Advances in Non-Contact High-Speed Jet Valve Technology
In recent years, non-contact high-speed jet valve technology has made significant progress in several aspects. First, in terms of dispensing speed, non-contact high-speed jet valves have achieved dispensing speeds as high as hundreds or even thousands of glue points per second, greatly improving production efficiency. Second, in terms of dispensing accuracy, through the optimization of the design and manufacturing process of the jet valve, non-contact high-speed jet valves have been able to achieve glue point sizes as small as a few nanoliters, and the tolerance is controlled within a very small range. In addition, non-contact high-speed jet valves also have advantages such as high flexibility, low maintenance cost, and long service life, allowing them to maintain stable performance under various complex and harsh working conditions.
In terms of technological innovation, some advanced non-contact high-speed jet valves have also integrated intelligent and automated elements. For example, by integrating sensors and control systems, non-contact high-speed jet valves can monitor and adjust dispensing parameters in real time to ensure the consistency and stability of dispensing quality. At the same time, combined with machine vision and artificial intelligence technology, non-contact high-speed jet valves can also achieve more complex dispensing patterns and shapes to meet more diverse production needs.

How can daily maintenance help extend the service life of a valve body?
As a precision component that operates at high frequency, the precision dispensing valve requires scientific daily maintenance to extend its service life and maintain dispensing accuracy. Shenzhen Laike Technology has compiled the following key maintenance points for you: Daily cleaning is crucial and should not be overlooked. After finishing work, promptly remove any residual adhesive from the exterior of the valve body, especially around the nozzle and plunger area. Once cured, adhesive can cause blockages or wear, affecting subsequent use. It is recommended to gently wipe with a suitable cleaning solvent, taking care not to damage the seals. Regularly inspect sealing components—seals and other parts will naturally degrade over time during prolonged operation. We recommend checking their condition periodically based on usage frequency. If you notice signs of hardening or wear, replace these components promptly to prevent adhesive from seeping into the valve body and causing more serious damage.
The stringing issue during the dispensing process is often closely related to fluid properties, equipment parameters, and process settings. Drawing on years of industry experience, SZLKTE has compiled and optimized key points for you: Fluid temperature control is crucial. Proper heating can reduce the viscosity of the adhesive, improve its flowability, and minimize stringing and trailing. SZLKTE’s dispensing valves can be equipped with precision temperature-control modules to ensure that the fluid remains in a consistently stable working state. The back-suction parameters must be finely adjusted. The negative-pressure back-suction applied at the moment the glue dispensing stops can effectively cut off the adhesive flow, preventing dripping and stringing. We recommend gradually adjusting the amount and speed of back-suction according to the adhesive’s viscosity until you find the ideal balance.
SZLKTE takes a multi-dimensional approach to ensure zero errors and long service life for its products even under high-speed, continuous operation. The piezoelectric valve series employs piezoceramic actuation technology; its non-contact drive design eliminates mechanical wear common in traditional solenoid valves, enabling a service life of over one billion cycles. At the same time, these valves deliver millisecond-level response times, completely eliminating trailing and stringing issues. The needle valve KC-9870, on the other hand, features a specially engineered, wear-resistant material for its needle component, offering exceptional resistance to abrasion and corrosion. Even in industrial environments with prolonged operation, this valve maintains outstanding stability. Moreover, its components can be quickly disassembled and maintained, significantly reducing production downtime.
Contact Dispensing vs. Non-Contact Jetting Valves: How Should You Choose for Micron-Level Processes?
Contact dispensing involves the needle making physical contact with the substrate surface to apply the fluid. Its main advantage lies in its strong adaptability to high-viscosity fluids and relatively controllable dispensing process. However, since it requires coordinated movement along the Z-axis, the dispensing speed is limited. Additionally, there is a risk of the needle colliding with and damaging the workpiece or deforming the needle itself. Therefore, careful evaluation is necessary when applying this method in miniaturized packaging scenarios. In contrast, non-contact jetting valves use a driving mechanism to rapidly spray adhesive onto the workpiece surface without any physical contact between the needle and the substrate. This feature makes them ideally suited for substrates with uneven surfaces or those that are fragile. They excel in micron-scale processes such as bottom-fill applications for chips and precision coating. The jetting method eliminates the need for Z-axis movement, significantly boosting production efficiency while also avoiding common issues associated with contact dispensing, such as stringing and trailing.
The stability of the piezoelectric valve dispensing process directly determines product quality. Common issues such as uneven dispensing, stringing, and glue leakage can be effectively addressed through parameter adjustments and optimized matching. Laike’s piezoelectric valves support multi-level parameter adjustments, enabling precise matching of pressure, injection frequency, and nozzle aperture according to the specific characteristics of different fluids.
Blocking the hole is Piezoelectric valve The most common failures in dispensing operations are often caused by fluid solidification, residual impurities, and nozzle wear, which directly affect dispensing accuracy and efficiency. Given the structural characteristics of piezoelectric valves, these issues can be addressed in three steps: “diagnosis—cleaning—inspection.” First, stop the machine and visually inspect the nozzle for obvious glue deposits or foreign objects, determining whether the blockage is temporary or a persistent issue caused by nozzle wear.
