Published in the April 2023 issue of Convertec: The World of Precision Dip Coating Suitable for Nanomaterials, Regardless of Workpiece Shape, and Its Latest Technologies.

It is an experimental dip coating device with a wide range of speeds and acceleration/deceleration functions.

The "DC Series" is a standard tabletop experimental device. By standardizing key functions such as processing speed, you can select the model based on the desired application length (application stroke). It covers a wide range of speeds (0.01 mm/s to 60 mm/s) while also pursuing precision operation at low speeds and considering user-friendliness and ease of use. Please check the catalog for detailed specifications. If you have any questions or wish to customize, please feel free to contact us.

Achieving a uniform coating film by using lifting and tilting functions for complex-shaped workpieces.

This device allows for the prevention of liquid pooling and approaches a uniform coating film by tilting the workpiece to an angle that facilitates liquid flow (Y-axis) during the lifting process (X-axis) for complex-shaped workpieces that are prone to liquid pooling in a vertical lifting posture. Additionally, for high-viscosity liquids that may cause dripping due to the posture after lifting, it is expected that changing the workpiece posture using the tilting function can also prevent dripping. As an option, it is possible to propose a 3-axis type by adding an additional axis and incorporating a rotation function to the tilt, allowing for a more uniform liquid flow onto the surface of cylindrical workpieces, resulting in a more uniform film formation.

• Other surface treatment equipment

The dip coater used as an experimental machine has been enhanced with a paint circulation unit and air conditioning system, expanding it into equipment suitable for sample production and small rod manufacturing.

By equipping the experimental machine, which tends to go into standby after completing experiments, with extended functionalities, it can transform into a facility capable of producing sample products that can be proposed to customers and small rod production as it progresses to the next stage. In reality, products formed by coating experiments such as dip coating often cannot be repurposed into sample products or actual products for customers due to irregularities in the appearance of the coated film. By reducing contamination, which is the main cause of these appearance irregularities, within the coating system, it is possible to dramatically decrease the disturbances in the coated film. ● Coating system for contamination reduction 1) Removal of contamination brought into the paint from the substrate (workpiece): Filtering during paint circulation and controlling the paint temperature within a certain range. 2) Increasing cleanliness by enclosing the coating area with a local booth and using a fan filter unit (FFU). The device that incorporates these two functions is the "FD200C2." We also offer the following options: - Monitoring of paint concentration and replenishment system - Temperature and humidity management within the local booth By adding these features, it becomes possible to provide even higher quality products.

"Because it's an invisible place, we won't overlook it." Japan's climate is characterized by high temperatures and humidity, and particularly after typhoons and heavy rains, the conditions can be harsh for homes. It's not just the roofs and exterior walls that are affected by rain and wind. The area beneath the floor is actually the most susceptible and often overlooked point. This time, we will explain the "checkpoints for under the floor" that should be confirmed after a typhoon or heavy rain, the "responses" if abnormalities are found, and measures for preventing recurrence. [Table of Contents] ■ Why is underfloor checking necessary? ■ Checkpoints to confirm after a typhoon or heavy rain ■ Responses when damage is discovered ■ Points for preventing recurrence ■ Suggestions from Seihou Products ■ Summary Please be sure to read the [related materials] and [related links]. ↓ ↓ ↓
