Reduce product defects and increase productivity of auto parts
The production of automobiles and parts involves important processes such as applying sealants and adhesives, and filling with grease.
This process requires highly precise, accurate, and stable liquid application.

problem
- A problem occurred where the coating material was scattered in areas other than the areas where it should be applied. In addition, bulges were observed at the starting and ending points of coating, and there were some areas where the film thickness was not uniform.
- When applying moisture-proof coating materials to substrates, problems such as air bubbles and dripping from the edges of the substrates occurred, making the quality unstable.
Benefits
- We were able to achieve a stable coating trajectory without scattering and avoid areas where coating is not permitted. In addition, stable coating improved bulges at the start and end of coating and unevenness in film thickness.
- Precise coating greatly reduces the occurrence of bubbles. Because the coating effect is uniform, the protection and reliability of parts has been improved.

problem
- When potting to protect and insulate the terminals of the ECU and protect the terminals from vibration and external influences, bubbles were generated during the process of injecting the liquid.
- If uniformity of application was not ensured, the liquid could not spread evenly over the part surface, resulting in a layer of uneven thickness or density.
Benefits
- The stable discharge is unaffected by pressure, temperature, and time, which reduces the generation of air bubbles and improves sealing and insulation properties during potting work.
- Consistent, high-precision coating work was possible while mixing the two liquids with a fixed amount within ±2%, and quality stability was maintained.
Introduced products
preeflow® eco-DUO330/450/600
The preeflow® eco-DUO series, a two-liquid positive displacement high-precision microdispenser, is a motor-driven high-precision dispenser that can mix and dispense two liquids at a constant rate within ±2% via a rotor and stator. Mixing is performed after increasing the quantitative properties of each liquid to achieve accurate mixing ratio and discharge volume.
problem
- A liquid gasket is applied to protect the inside of a battery, and it was difficult to maintain a uniform coating width and thickness.
- The amount of coating was not stable, product defects due to stringing occurred frequently, and production efficiency was poor due to correction work.
Benefits
- With the introduction of the vipro-PUMP series, it has become possible to ensure uniform width and thickness when applying liquid gaskets through precise control.
- The coating amount has been stabilized, product defects due to stringing have been significantly reduced, the frequency of correction work has been reduced, and product quality and production efficiency have been improved.

problem
In order to obtain the optimal heat dissipation characteristics for EV battery units, the heat dissipation material applied has a high proportion of inorganic filler, which tends to cause wear. Parts had to be replaced frequently due to wear.
Benefits
The durability of ceramic rotors has significantly reduced the frequency with which rotors and stators need to be replaced. This reduces the frequency of maintenance and reduces replacement costs and downtime.
