What is a syringe?

In the dispensing process, a syringe is a container used to hold and apply liquid materials such as adhesives, solder paste, and grease. The precision and stability of the application depend not only on the performance of the dispenser but also on the inner diameter precision and shape of the syringe. Therefore, using a higher-performance syringe can be expected to improve yield and quality.

Features of our syringes

In dispensing, variations in discharge volume and dripping can occur, and these are also influenced by the performance of the syringe. To address these issues, our company adopts a design that prioritizes discharge stability.

Feature 1 | Stabilization of dispensing through a straight inner diameter structure

If the inner diameter of the lower part of the syringe is narrower than the upper part, the plunger reaching the lower part can encounter resistance, which may affect discharge accuracy. Our syringes prioritize discharge stability and adopt a straight inner diameter structure, allowing for high-precision discharge from the beginning to the end of production.

Furthermore, if resistance becomes strong in areas such as the lower part of the syringe where the inner diameter narrows, and the plunger cannot descend smoothly, air can easily enter between the plunger and the liquid surface, which can also cause "bouncing."

Tips

What is bouncing?

This is a phenomenon where the plunger, which is temporarily pushed down by pressure, returns to its original position when the pressure is stopped. It is called "bouncing" because the plunger appears to be bouncing. In addition to the accuracy of the syringe inner diameter, it can also be caused by filling and storage conditions.

Our straight inner diameter structure is also effective against such phenomena.

Note that discharge variations and instability are significantly affected not only by bouncing but also by "head pressure differences." The causes of changes in discharge volume and the concepts behind them are explained in the following article.

Feature 2 | Plunger structure that suppresses air bubble entrapment

To suppress the generation of air bubbles and variations in discharge, we offer a lineup of plungers equipped with a slit structure. By discharging internal air through the slits, we prevent air bubbles from remaining inside the syringe.

About UV Block Syringes
(Syringes for UV-curable resins)

There are syringe products designed for liquid materials that cure in response to ultraviolet (UV) light (UV-cut syringes). These liquid materials, known as UV-curable resins, are used in many industrial fields, including adhesives, paints, inks, and coating materials. A major feature is that they can be processed in a short time as the reaction proceeds upon exposure to UV light. However, if the material is exposed to UV light contained in indoor lighting or sunlight during storage, transport, or the dispensing process after filling, it may react inside the syringe, leading to dispensing failures or material loss. Therefore, it is important to choose a syringe with quality that can block 100% of UV light.
