flame plasma treatment
closeBtn
  • What is the flame plasma treatment?

    The flame plasma treatment is a treatment that creates a layer of molecular oxygen on the surface of a material, thereby increasing surface energy and improving adhesion. This creates an optimum surface for painting, printing, bonding, and laminating in the preprocess stage.
    Doolim Robotics’ flame plasma treatment improves the quality of intermediate and final coats by altering the surface properties of plastic parts for automobiles, such as bumpers and garnish.

    Composition of the Flame Plasma Treatment System

    외판 실링의 시스템 구성

    1. Robot
    A six-axis, multi-joint robot is controlled by worker-provided instructions to apply the flame to every inch of automobile bumpers.
    The six-axis robot is equipped with an RC control.
    2. Flame equipment
    The flame equipment is composed of a burner for combustion and additional components for the operation of the burner, including a gas flow meter, gas safety valve, Venturi Unimixer, pressure controller, pressure switch, and gas trim control valve.
    3. Flame Controller
    The flame controller regulates the flame produced by the burner. It controls the start sequences and gas trim control valve, and also adjusts time intervals to ensure accurate operation.
    4. MCP
    The MCP (main control panel) controls a number of robots and the conveyer.
    5. HMI
    Developed by Doolim Robotics, the HMI is an interface that controls the flame robot and flame equipment. Also it can monitor condition of each flame equipped robot operation, progress status, alarm and make any changes.

    Main Factors of the Flame Plasma Treatment Syste

    Doolim Robotics has the capability to perfectly control the following four main factors in flame plasma treatment system in order to create the surface tension customers want.

    1. Amount of oxygen included in the flame (gas to air ratio)
    The flame treatment system of Doolim Robotics is equipped with an oxygen analysis device that accurately measures the air to gas ratio of the burning flame.
    2. Distance between the product and the burner
    Doolim Robotics’ flame plasma treatment system maintains a constant distance between the flame and the product at all times by exercising perfect control over the robot.
    3. Flame treatment time
    The flame plasma treatment system is able to achieve 90 percent of the desired surface energy in the first phase thanks to its precision robot control capability and optimum system configuration.
    4. Flame size
    The flame plasma treatment system controls the size of the flame by adjusting the combustion speed of the mixed gas and handles complex products with certainty through precision speed control.
primer coat
closeBtn
  • What is the primer coat?

    The primer coat is the first coat of paint applied. It protects the bumper surface and enhances the properties of the base coat. It smooths out the rough surface of the bumper—caused by the flame treatment—and increasing the adhesion of the base coat.
    Since the regulations on the emission of volatile organic compounds have been strengthened, the demand for water-based primer coats has increased considerably. Therefore, Doolim Robotics built a water-based painting system in 2013, the first of its kind in Korea, and now possesses top level expertise and solutions regarding both water- and oil-based painting.

    System Composition of the Primer Coat

    1. Robotic painting system
    The robotic painting system is composed of six-axis, multi-joint robots controlled by worker-provided instructions to spray paint on every inch of the automobile bodies.
    The six-axis robot is controlled via an RC panel.
    2. Painting equipment
    The painting equipment allows the robot to apply the paint to the automobile bodies effectively, and is composed of an atomizer that converts the paint into a fine spray, an RF block that cleans and fills the paint, a CCV that prevents paint congestion, and an AOPR that controls the paint pressure.
    3. Constant flow device
    The constant flow device allows the painting equipment to discharge a steady, consistent flow of paint. It is composed of an FGP that controls the amount of flow, an FGP servo motor that rotates the FGP, and an FGP servo amp that controls the FGP servo motor.
    4. MCP
    The MCP (main control panel) controls a number of robots and automated guided vehicles. The automated guided vehicles are part of a conveyor system that is used to move the robots while they spray paint on the automobile bodies.
    5. Air panel
    Air pressure is required to move the paint through the painting equipment. The air panel maintains the smooth flow of paint and regulates the high voltage used by the painting equipment.
    6. HMI
    The HMI controls the robotic painting system and the painting equipment. Developed by Doolim Robotics, the HMI monitors for each robot, the condition of the painting equipment, operation and progress status, operation and alarm, and controls all factors that affect the paint quality, including the discharge amount, turbine speed, and air flow shaping.
Bumper base coat

  • What is the base coat?

    The base coat is applied over the primer coat and determines the visual properties of the automobile, such as color. It enhances the aesthetic appeal of the automobile. The paint used for base coat should adhere well to the primer coat and block ultraviolet rays.
    Since the base coat is responsible for the color, it has the greatest impact on the esthetic aspect of the automobile. Through years of experience, Doolim Robotics has accumulated the necessary solutions for proper paint formation and paint flow.

Bumper clear coat

  • What is clear coat?

    The clear coat is a layer of clear paint applied over the base coat to protect the paint and create a glossy, transparent coating. The clear coat must be durable enough to protect and maintain the surface in the long term, and be resistant to external conditions, including water, ultraviolet rays, and chemicals.
    It requires good understanding and extensive experience with clear paint to effectively apply a protective clear coat. Doolim Robotics has come to an intimate understanding of clear paint throughout its years of experience and numerous tests. This understanding ensures that the process is carried out effectively and the best body finish possible is achieved.
