Tabletop Dip Coater (Dip Coating Device) DC Series

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.

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.

Here are three representative coating methods for dip coating: 1) Basic Type: Constant Speed Lift in Vertical Position - What is dip coating? - Parameters for film formation - Relationship between lift speed and film thickness 2) Linear Processing: Linear Deceleration of Lift Speed - What is linear processing? - Film thickness data for linear processing - Speed at each point (position) of the above data 3) Elevation, Inclination, and Rotation: Multi-Axis Lifting - Image diagram of synchronized lifting for curved workpieces - Film thickness data for the above processing - There was not enough space for the rotation axis function: Please contact us directly.

●From the overview of dip coating, we explain our precise speed control based on film thickness data regarding the uniform coating results at low-speed ranges (approximately 0.1 mm/sec to 3 mm/sec) and how to address the tendency for thicker films at the lower part of the coating surface due to the weight of the liquid during high-speed ranges (5 mm/sec and above). ●We explain the strength of dip coating, which is the "liquid followability," based on our precise lifting control aimed at achieving uniform coating on various workpiece shapes, using illustrations and film thickness data. In this way, we introduce our coating methods utilizing precise dip coating through speed control and lifting control, addressing coating on various shaped workpieces and research and development in the field of nanomaterials.
