    Compared to low-pressure spraying technology, our company's new high-speed spraying equipment adopts advanced technologies such as precise adjustable spacing technology, high viscosity technology, high-speed robotic arm, and dry filtration. This reduces ink overspray and air spray, increasing production by 30% compared to low-pressure spraying. Additionally, it has no wastewater discharge and does not require frequent replacement of filter cotton. It is suitable for high viscosity inks, reducing ink diluent usage, and decreasing VOC emissions by 20%, thereby reducing pollutants from the source and making it more environmentally friendly.

    Ink uniformity test method : test on 625*726mm bare copper plate . After drying, use the 9 -point method of the ink tester to measure ( dry film thickness 30 ~40μm ); calculation formula : 100%- ( maximum value - minimum value ) / (2 * Average ) *100% .
     

    Product Features 

    1. High yield: Using a mixed air spray gun to increase ink output,the production line speed is 3.0-4.5m/min ,and the output is increased by 30% compares to low-pressure spraying.

    2. Ink Efficient: Adopting precise adjustable spacing technology to reduce the ink spray area between circuit boards;Ultra hig acceleration design,shorter spray distance compared to low-pressure spray machines,reduces ink waste by 30%,and lowers raw material costs.


    3. Less exhaust gas: Using high viscosity ink,reducing the amount of ink diluent,reducing VOCs emissions for waste gas tratment.


    4. Thick copper plate: Adopting a high viscosity oil supply system,the viscosity is increased by three times compared to low-pressure spraying machines,There is more hanging oil at the corners of the line.The 3oz thick copper plate can be sprayed in one go,reducing drying times,increasing production,and saving energy.
