Fast-switching coaxial solenoid valves play a central role in the ink control of the ink supply to printing presses, especially in modern inking units, where precise, fast and reliable control of the ink supply is crucial for print quality. Here are the applications and advantages of fast-switching coaxial solenoid valves in this area:
Application of fast-switching solenoid valves in ink control
- Ink flow control: Fast-switching solenoid valves are used in printing presses to precisely control the ink flow in the inking units. They regulate the amount of ink that is applied to the printing plates and ultimately to the substrate (paper or other materials).
- Color change: In modern printing presses that require frequent changes between different colors (e.g. in packaging or label production), solenoid valves enable fast and efficient color changes. This saves time and reduces ink waste.
- Precise dosing: Due to the fast switching speed of the solenoid valves, very small quantities of ink can be dosed and applied in short intervals, resulting in uniform and high-quality ink distribution.
- Automation and process integration: Fast-switching solenoid valves can be seamlessly integrated into automated printing systems, allowing ink application to be digitally controlled and monitored. This is particularly important for high-speed printing processes and large print runs.
Advantages of fast-switching coaxial solenoid valves in paint control
- Precise control of the ink quantity: Fast-switching solenoid valves enable extremely precise control of the ink quantity used for printing. This results in consistent print quality and avoids fluctuations in color intensity or distribution.
- Faster production times: With the ability to switch quickly and efficiently, solenoid valves allow for speedy color changes and faster adjustment of ink flow. This reduces downtime and increases press productivity.
- Reduced ink consumption: As dosing is very precise, only the required amount of ink is applied. This reduces ink consumption and waste, which offers both economic and ecological benefits.
- Consistent print quality: The fast response time of the valves ensures that the ink is always applied at the right moment. This leads to an even distribution of the ink on the print material, which is particularly important for high-speed printing.
- Simplified colour change: Solenoid valves make it easier to switch between different colors by precisely controlling the ink flow and minimizing contamination between colors. This saves time and increases efficiency, especially in multicolor printing processes.
- Longer press life: Precise control and reduction of ink consumption reduces wear on the mechanical components of the press, extending its life and reducing maintenance costs.
- Compact design: Coaxial solenoid valves (also known as inline valves) have a very compact design and require little installation space. They are therefore easy to integrate into systems.
- Low maintenance and easy to clean: Due to their simple design with clear flow guidance, BFS coaxial solenoid valves require little maintenance and can be easily cleaned in the general flushing process.
Summary
Fast-switching coaxial solenoid valves in the color control of printing presses offer decisive advantages such as precise color control, faster color changes, increased productivity and consistently high print quality. They help to increase efficiency and reduce costs in modern printing processes, especially in highly automated and color-intensive printing environments.
