エコートプレシジョン Company Profile

Our company has been engaged in coating equipment primarily focused on dip coating. Among these, we have received numerous inquiries from companies such as paper manufacturers and manufacturers and sellers of molded containers regarding coatings aimed at providing "water resistance, heat resistance, and oil resistance" for three-dimensional shapes like pulp (paper) molds. We are conducting test coatings on prototype containers (pulp (paper) molds). Based on the results of these test coatings, we have developed a dedicated testing machine called the "Pulp Coater." The Pulp Coater catalog includes the following information regarding coating film performance: - Water and heat resistance: Changes over time after heating in a microwave (up to 72 hours) - Oil repellency KIT value - Oil resistance: Changes over time after applying salad oil, dressing, and soy sauce to the container (up to 24 hours) In light of the movement to reduce plastic use, companies considering a switch to materials with less environmental impact, especially those looking to convert disposable containers to pulp (paper) molds, are encouraged to make use of the Pulp Coater. Please feel free to contact us for inquiries regarding test coatings and other matters.

When it comes to AR (anti-reflective) coatings, they are widely recognized for being applied through a dry process, but it is also possible to achieve a reflectance of less than 1% (on one side) with a single-layer coating using the wet process dip coating method. By varying the withdrawal speed during dip coating, we have successfully controlled the film thickness in increments of 5 nm, achieving thicknesses ranging from 100 to 160 nm, as demonstrated by our film thickness analysis data. The ability to control film thickness by varying the withdrawal speed allows us to target specific bottom wavelengths, making it possible to achieve the desired film deposition for optical lenses that require bottom wavelength ranges of 550 nm to 650 nm, as well as for sensors (LiDAR) used in autonomous driving that require wavelengths around 1500 nm, depending on the purpose and application. In this catalog, the withdrawal speed varies according to the coating agent, and we have included analysis data for each film thickness.

We would like to introduce the coating process and various mechanisms of the mass production dip coater (coating device) that our company has been manufacturing so far. In reality, what kind of mechanisms are involved in an automatic mass production dip coating device? How is the coating applied? What are the important factors to consider when constructing and selecting these mechanisms? This content addresses these questions from a coating perspective. *The aspects of mass production and productivity will be introduced separately. We hope that the overview of the devices we have constructed and manufactured based on the following considerations will serve as a reference for those considering coating. ● Dip Coater (Coating Device) for Obtaining High-Quality Coating Films "What is a high-quality coating film?" We believe it can be summarized in the following two points: - Cleanliness: Minimal film unevenness, drips, defects, accumulations, and deviations. - Sufficient durability: Adequate adhesion between the substrate and the paint. The performance of the coating film depends on the paint, but to bring out the performance of that paint, it is necessary to consider the three processes: pre-coating cleaning/modification process, dip coating process, and drying (curing) process, along with the key points of each mechanism.
