Needle Nozzle is one of the key parts for high-quality application at manufacturing sites. In order to meet a wide range of applications, such as precise liquid discharge, adhesion, and coating, there are various types and shapes, and the correct selection according to the characteristics and application of the product greatly improves the efficiency and quality of the manufacturing process.
In this article, we will explain in detail the broad lineup of Musashi Engineering's needle Nozzle and the points of selection.
※We have a needle Nozzle instead of a Nozzle needle.
There are four key points when selecting a needle Nozzle.
The material of the needle Nozzle is roughly classified into metal or resin. For example, if the liquid is a material that is not compatible with resins such as organic solvents, it is desirable to select a metal. On the other hand, when dealing with materials that are reactive to metal, such as anaerobic adhesives, it is necessary to select resin products.
| Made of metal | Made of resin |
|---|---|
In addition, not only the reactivity with the liquid, but also the presence or absence of permeability may be a condition for judgment. When using UV-curing resin, which reacts and hardens with UV light, it is necessary to use needle Nozzle made of materials that do not pass UV light.
| Pass through UV | Do not pass through UV |
|---|---|
The shape of the needle Nozzle is roughly classified into straight and taper. Nozzle, which has a straight shape, generally has a pipe shape with a certain length, has a high pipe resistance and the high viscosity liquid is difficult to flow, but the low viscosity liquid is less likely to drain. On the other hand, Nozzle, which has a taper shape, has a small resistance during liquid dispensing and excellent fluidity, is suitable for expelling highly viscosity materials in a short time.
| Straight shape | Tapa shape |
|---|---|
| Low viscosity material is hard to drain. | High viscosity materials are easily discharged |
Depending on the shape of the workpiece, the selection point is whether Nozzle can access the place it wants to apply. For example, if a taper shape interferes with the thick part, we use a straight-shaped Nozzle or a product with a long needle tip. Depending on workability, a resin Nozzle that is hard to damage the workpiece may be suitable. There is also a lineup of bent Nozzle that can penetrate narrow areas.
In many adhesive processes, dot and line application shapes are used, but special Nozzle can be used to achieve application of different shapes. A typical example is the slit Nozzle, which allows you to perform coating with a single application.
| Dot dispensing Line application | Surface application | Dot dispensing |

Please reduce these four points and select the optimal Nozzle according to your purpose. When choosing the type and size of Nozzle, we recommend the Nozzle Kit, which comes with basic Nozzle. A total of nine types of Nozzle are one. Of course, if you have any questions or concerns about the selection or application evaluation, please contact us.
