I. Working Principle of Ink Spray Valve
The core of the ink spray valve lies in its precise control system and nozzle design. During operation, high-pressure gas passes through the internal channels of the valve body, pushing the piston or diaphragm to quickly open or close the nozzle, achieving instantaneous injection and shutoff of the ink. This process relies on the precise control of driving elements such as solenoid valves or piezoelectric ceramics, ensuring that the ink is sprayed out with stable and uniform pressure and flow rate, forming a fine and uniform coating. In addition, some high-end models of ink spray valves are also equipped with flow regulation and pressure feedback mechanisms, further improving the accuracy and consistency of spraying.
II. Main Characteristics of Ink Spray Valve
1. High-precision control: With the help of an advanced electronic control system, the ink spray valve can achieve millisecond-level on/off response, ensuring that the edges of the sprayed pattern are clear and accurately positioned.
2. Energy saving and environmental protection: By precisely controlling the amount of ink sprayed, waste is reduced, and at the same time, the efficient atomization effect helps reduce solvent volatilization, meeting environmental protection requirements.
3. Strong adaptability: The ink spray valve is suitable for various types of inks, including water-based, oil-based, and UV-curable inks, and the nozzle structure and spray mode can be adjusted according to the spraying needs of different materials.
4. Easy maintenance: The modular design makes it easy and quick to replace nozzles and clean the valve body, reducing maintenance costs and extending the service life of the equipment.
III. Applications of Ink Spray Valve in the Packaging Printing Industry
In the packaging printing field, the ink spray valve is one of the key technologies for achieving personalized packaging and improving production efficiency. For example, on the surface of packaging materials such as corrugated boxes, plastic bottles, and metal cans, variable data printing (such as production date, batch number, QR code, etc.) is performed using an ink spray valve, which not only improves the anti-counterfeiting and traceability of the packaging but also meets the market demand for customized packaging. In addition, for high-end gift boxes, wine labels, and other fine-printed products, the high-precision control capability of the ink spray valve ensures the fineness and color reproduction of the pattern, improving the overall visual effect of the product.
IV. Applications of Ink Spray Valve in Electronics Manufacturing
In the manufacturing process of electronic products, the shells, circuit boards, and other components often require precise marking and protective treatment. Because of its ability to precisely control the amount of ink, the ink spray valve is widely used in printing characters, barcodes, and markings on electronic components on printed circuit boards, ensuring that the marking information is clear and legible, while meeting the special requirements of electronic products for moisture and corrosion resistance. In the 3D printing field, specific types of ink spray valves are also used to manufacture prototypes of complex electronic components, accelerating the development cycle of new products.
V. Ink Spray Valve in Automotive Manufacturing and Painting Industry
In automobile manufacturing, car body painting is a crucial link, directly related to the appearance quality and corrosion resistance of the vehicle. The ink spray valve plays a key role here. It can achieve uniform and efficient spraying operations according to the curves and surfaces of the car body, reducing overspray and under-spray phenomena, and improving the uniformity and gloss of the coating. Especially on automated painting lines, combined with the use of robotic arms, the ink spray valve achieves a high degree of automation and intelligence, significantly improving production efficiency and painting quality.
With its high-precision control, energy saving and environmental protection, strong adaptability, and easy maintenance, the ink spray valve shows broad application prospects in various industries such as packaging printing, electronics manufacturing, and automobile manufacturing. With continuous technological advancements and innovations, the performance of ink spray valves will become even more superior, and their Applications will be further expanded, contributing to the high-quality development of modern manufacturing.

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.
