Dip Coater (Coating): Introduction to the Coating Flow

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.

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.

This is a dip coating device equipped with ultrasonic functionality aimed at liquid circulation (four-sided overflow) and liquid penetration into fine details of the substrate.

This is a standalone device equipped with lifting functionality, liquid circulation functionality, and ultrasonic functionality aimed at liquid penetration into the fine details of the substrate. ◆ Benefits of 4-Sided Liquid Circulation Overflow - It can maintain a constant liquid level at all times. - The circulation path can be managed with the following functions: - Liquid temperature and concentration can be managed within a certain range. - Contaminants introduced into the liquid can be removed. ◆ Ultrasonic Function Aimed at Liquid Penetration into Fine Pores of the Workpiece ◆ Since humidity is undesirable after coating, a nitrogen purge function has been added to the dip lifting section and the liquid tank (with automatic lid). By incorporating additional functions tailored to the characteristics of the substrate and coating agent as described above, we strive to provide devices that meet our customers' objectives.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If you require a detailed technical explanation, please contact us.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repair without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.
