Atmospheric Plasma Coating Machine

1. Plasma inverter power supply:

     Provide DC power for the plasma coating gun, Using IGBT modules, intelligent module control, soft-starting arc, small size, high efficiency, low power consumption, good heat dissipation can work continuously low failure rate is the best plasma power supply. 

2. Control cabinet:

     It can automatically control the spraying process, ignition, soft-start, soft-off; voltage and current adjustable when work; and with water temperature, voltage, water pressure automatic protection function; for water, electricity, gas, powder Regulation and control. It can monitor the entire system, the user can directly understand the system from the control cabinet when the system parameters, such as voltage and current size can be read directly, when the system of electricity and gas have the same requirements, the system will Automatic alarm to remind the user to do the appropriate adjustment. The temperature of the plasma arc is adjusted by adjusting the current and voltage on the panel. Users can also control the main gas through the control panel, the second gas to control the gas flow and gas ratio to change the length of the plasma arc and the flame velocity of the final powder particles to change the speed to ensure the accuracy of repeated experiments, the other control cabinet (Power users can set their own), spraying (power users can set their own), so that customers spray in a long time, need to have a metal powder rendering, it can be (3KW or so) Through a knob to automatically switch parameters, simple, convenient and applicable.

 3. Powder feeder

      It for storing the powder and delivering the powder to the spray gun as required. The main gas of the spray gun is used as a powder feeding gas, and the powder is transported to the outlet of the powder feeder through the rotation of the powder feeding scraper, and the powder is separated from the powder feeding barrel through the gas pressure to enter the spray gun. Adjust the potentiometer on the control panel to adjust the feed speed.

4. Water and electricity mixed cabinet

    It mixed the water and electricity and sent to the spray gun, providing the high-frequency pulse voltage for gun arc start and detection of water temperature and cooling water spray pressure, lightweight and flexible, easy to drag. Arc performance well, reduces the momentary impact of the nozzle arc. 

 5. Plasma coating gun:

    It for the production of plasma coating operations, the working power can up to 50KW, so it can use high powder delivery power, shorten the spraying time and reduce processing costs. The standard architecture allows for fast hardware replacement

 6. Heat exchanger/cooling system:

    Dual compressor drive to reduce the size of the machine, at the same time the coating guns get better cooling, then extend the life of the nozzle.

7. Plasma water & electric cables:
    The use of Italian imports PVC pipe, burst pressure high to 6 Mpa, working pressure 2Mpa, the maximum DC current 1000A, rated current high to 650A,. It can long-term continuously working when the working temperature is below 55 ° C

8. Multi-function coating chamber:

     It is made of cold plate welding, including box door, observation window dust removal system, lighting system and dust removal system. It with a small, easy to operate, both noise, dust and radiation protection, so particularly suitable for spray coating operation and sample preparation.
