Which automatic dispenser technology can meet the expected requirements for the painting of gold jewellery? Recommend you use vision automatic dispenser, micro-control glue technology and spray paint process are to meet the requirements of low-viscosity glue spraying technology, paint also belongs to the low-viscosity glue, vision automatic dispenser for gold jewellery varnishing is a high-pressure way of spraying, paint from the paint dispensing valve shot, directly will be glued in the jewellery, will not appear the flow of the situation.
Gold jewellery varnishing
Paint Dispensing Valve is a member of Jet Dispensing Valve, which is mainly used for paint spraying, and it is also controlled by piezoelectricity, and air pressure is used as the pressure for spraying. There are two similar spray paint dispensing valve, the first, directly connected to the pressure barrel, the second, the use of dispensing syringe, the general amount of small products will use the second way, for example: PCB board gluing, in the gold jewellery painting recommended that you use the second way, directly connected to the pressure barrel, the use of pressure barrels the biggest advantage lies in the storage capacity is more, visual automatic dispensing machine standard 25 litre drum, quite storage of twenty-five litres of paint, the It is possible to spray paint from morning to evening, if the use of large quantities, you can choose the appropriate type of pressure drum.
Gold jewellery painting requirements
Micro-control glue technology on the dispensing market at present, that is, the visual ab glue automatic dispenser is better, other ordinary glue simply can not meet the five gold jewellery on the paint, unless the requirements of the large amount of glue, only to choose the ordinary coating equipment, and gold jewellery will be coated on the top of the coating, is a relatively thin layer of film can only be used to the vision of automatic dispenser and paint dispensing valves to be able to achieve the technology, the other types of machines are very difficult to Completed the task, gold jewellery painting or choose to have a good paint spraying process is more ooh.
Micro-control glue technology
Micro-control glue technology is generally the use of low-viscosity glue, to be able to glue spray, high-viscosity glue is very difficult to spray paint, so the micro-control glue technology is mainly micro-glue can be achieved, the development of spray paint process, so that hardware products and accessories on the effect of paint is easier to visual ab glue automatic dispenser technology can be achieved by the spray paint process technology to meet the industry is very much, especially with visual Control technology with visual automatic dispenser, hardware and jewellery varnishing effect is really great!

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, Shenzhen Laike Technology 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. Laike Technology’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.
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.
Piezoelectric valve: A highly efficient core component in the field of precision automation.
Piezoelectric valves leverage the inverse piezoelectric effect of piezoceramics to achieve precise control. With advantages such as low energy consumption, silent operation, and rapid response, they have become critical equipment in the field of precision manufacturing. Unlike traditional solenoid valves, which require continuous current to maintain their operating state, piezoelectric valves consume far less energy. Moreover, they operate without generating heat or producing magnetic interference, making them well-suited for high-demand operational environments.
