Drop-on-demand (DoD) painting technology

Drop-on-demand (DoD) painting technology is an advanced method for the precise and efficient application of paint materials to a wide variety of surfaces. With this technique, tiny amounts of paint are selectively and specifically applied to the substrate, allowing precise control of the amount and position of paint.

The name "drop-on-demand" already indicates the underlying functional principle: paint drops are only produced and dispensed when they are actually needed. This is achieved by controlling piezoelectric or thermal actuators, which cause small quantities of paint to be ejected from a nozzle. The nozzles are usually very fine, which makes it possible to produce precise droplets with high resolution.

DoD painting technology offers a number of advantages over conventional painting techniques. These include:

1. precise control: by precisely controlling the droplets, paint quantities can be accurately dosed and adapted to the specific requirements of the application.

2. low paint consumption: As only drops of paint are applied when they are needed, paint consumption is reduced compared to continuous spraying or dipping processes.

3. lower environmental impact: With reduced paint consumption and precise control of application, DoD painting techniques can lead to a reduction in paint waste and environmental impact.

4. versatility: DoD technology can be applied to a variety of surfaces, including flat, curved or uneven surfaces.

DoD painting technology is used in various industries, including the automotive, electronics manufacturing, packaging and medical industries. It provides an efficient and precise solution for painting products and components and enables high quality and consistency in paint application.
