    ·immersion  tank by stainless steel

    Steps:
    we always have 4 solutions for our customs.
    1.Pretreatment plan No.1.
    With 7 bin as your requirest
     the 7 bin function is in order as bellow .
    1. degrease
    2.washing
    3.pickling
    4.washing
    5.surface conditioning
    6.phosphorization
    7.washing

    4 bins is also ok,7 bins is a standard flow for pretreatment,can be adjustable as your need.

    just 4 or 7 bins with 1 set heating function  

    2.Pretreatment plan No.2.  
    4 bins with 1set of hang railing;1 set track frame;1set cranes with load 1 ton;1set electric control system(including heating system)

    3.Pretreatment plan No.3.
    preprareed by yourself with cement tank ,it really can save a lot.and we can supply you the lifting system.

    4.Pretreatment plan No.3.
    showering like pretreatment as attached.but it is high cost.
    Have any pre-established designs of processes with pre-treatment, powder paint and oven continuous?
    Showering type is together with the whole powder coating line,

    *Please include all drawings and images as possible to explain general function of automatic equipment’s..
    *Also include all general info and drawings of pre-treatment designs and function of your products
    Thank you!

    What Are the Different Types of Powder Coating Equipment?

    A

    There are several types of powder coating equipment used for coating metal. The most common types of equipment for applying powder coating include the electrostatic spray gun and the fluidized bed. These are used to evenly coat the workpiece with powder, creating a chip-resistant finish that is more durable than a traditional paint finish. Other types of powder coating equipment include recovery systems, spray booths and cure ovens.
    One of the oldest methods for applying powder coat is the fluidized bed dipping process. A basic fluidized bed is made up of a tank, an air supply and a plenum, or membrane that allows air to pass but not solids. As air is introduced to the plenum, thermoplastic powder is suspended, or fluidized. The heated workpiece is then dipped into the fluidized powder. Some fluidized beds also have the ability to electrostatically charge the powder, allowing the use of a tougher thermoset polymer instead of thermoplastic powder.
    Among the newer and more commonly used types of powder coating equipment are electrostatic spray guns. There are three basic types of powder coating spray guns. All of them rely on a fluidized bed or tank to hold the powder and an air supply to fluidize the powder and deliver it to the gun. The main difference between these three types of powder coating equipment is the mechanism used for applying the charge to the thermoset polymer.

  • Q

    Principle of Electrostatic Coating Guns

    A

    Electrostatic spray application uses a fluidized bed as a feed hopper to hold the powder and fluidize it so that it can be pumped to the tip of a spray gun using compressed air for transport from the feed hopper to the gun tip.
    The spray gun is designed to impart an electrostatic charge to the powder material and direct it toward a grounded workpiece. This process makes it possible to apply much thinner coatings with a wide variety of decorative and protective features.
    The electrostatic charge can be imparted with voltage, called corona charging, or by frictional contact with the inside of the gun barrel, called tribo charging.
    In a corona charging system, a voltage source generates current through a voltage cable that carries it to the powder gun tip. Powder is pumped through the gun and out of the gun tip using compressed air. As the powder passes through the electrostatic field at the gun tip, it picks up a charge and is attracted to a grounded substrate. The part is then conveyed into an oven for curing of the powder. In the cure oven, the powder melts and cross-links to a hard film to complete the process.
    Electrostatic spray application of powder is the most common application method. The parts to be coated are cleaned, dried, and cooled, the coating is applied and cured at the required temperature for the required time and then cooled for removal from the line.
    An electrostatic spray application system includes a delivery system and a charging system.

    How To Solve The Color Deviation In The Powder Coating

    A

     easons and solutions:
    Color deviation:
      (1) caused by the uneven distribution of the powder paint. The solution is to improve the quality of the powder to ensure that the powder L, a, b or less and negative unity.
      (2) caused by different curing temperatures. The solution is to control the set temperature and the conveyor speed in order to maintain the consistency and curing temperature and time stability of the workpiece.
      (3) result in uneven coating thickness. The solution is to adjust the process parameters and ensure powder coating equipment running well in order to ensure a uniform coating thickness is consistent

    What Is Electrostatic Powder Coating?
    In manufacturing, electrostatic powder coating is a type of finishing process during which dry powdered paint is applied to metal. By applying an electric charge to the paint particles as they're applied, manufacturers can create a permanent, high-quality finish. Dating back to the 1960s, electrostatic powder coating remains one of the most common powder coating processes today. It creates a finish similar to that created by wet paint, but offers a number of advantages in terms of finish quality and environmental issues.
    Manufacturers may apply an electrostatic powder coating to many types of products. This type of finish is primarily used on metals ranging from steel to aluminum. It's also used to finish a variety of consumer goods, from wire shelving to lawn furniture. Electrostatic powder coating is also used on cars and other vehicles, and remains a popular method of finishing exterior metal siding.
    This product may contain a variety of materials, depending on the product and manufacturer. Many include an epoxy resin base, though some rely on polyester-based hybrid mixtures instead. While polyester reduces the risk of yellowing on a powder coated finish, it also offers less corrosion resistance. Acrylic products are used to create a electrostatic powder coating with a high-gloss finish, while enamel-based versions are commonly used to finish electronic and mechanical equipment.
