Additional Capabilities Include Internal Video Inspection, Induction Heat Services & The Custom Engineering & Construction Of Pipe & Rebar Coating Plants. It's basically a low-tech coating method, and once coating parameters are established, there are not that many things that can go wrong. Compared to the corona spray gun, no high voltage is required, and there is no risk of issues arising due to the Faraday Cage Effect. Electrostatic fluidization bed for powder coating machine sale. ISO 9001:2000 certified surface treatment service for anti-wear & anti-corrosion applications.
Before a powder coating can be applied it must be converted into a fluid. On the downside, a Tribo gun is not compatible with all powder coatings, and there are limits on particle size. When you work with experts in the powder coating field, like Precision Coating Technology & Manufacturing (PCTM), we'll ensure that you understand the process and benefits of this type of powder coating and get the best fluidized bed coating for your product. The powder particles lose electrons during this process and become positively charged. Electrostatic fluidization bed for powder coating machine shops. The preheating of parts is not necessary with this method. Air supply and rat holes. Simple request a quote from our team, send us your product, and we'll take it from there! Normally, the corona is negatively charged resulting in a flow of negative ions from the gun to the substrate.
This type of powder coating is ideal for parts that need a thick, even layer but without a lot of details. Three types of electrostatic guns are available: Corona, Tribo, and Rotary bell. Heat treating & coating services for wear & corrosion resistance. The degree of acceptance is directly related to the electrical conductivity of the particle. Difficult color changes in automatic systems comparable to Tribo systems. We keep the part submerged in the fluid bed for powder paint to allow the film to coat parts with a thick, wear-resistant coating. Iron Phosphate Wash. - Transition Metal Wash. Industrial Powder Coating Systems, Mechanical Finishing Systems, , 574-312-0923. Masking. Fluid Bed Powder Coating is sponsored by PECOAT® Thermoplastic Coatings. Industries served include appliance, automotive, agricultural, military, metal processing, heavy equipment and medical. The rate at which powder collects on the part at the beginning of the exposure increases as the voltage increases. These are ideal to coat smaller, more complex workpieces. This way you will know when the hopper is or is close to being, overfilled.
FBD relies on the preheated metal to dose out the heat to melt and build a film. Multiple dips for even thicker coatings. As powder contacts these non-conductive surfaces, electrons are stripped off of the particles due to friction. It generally applies a thin coat vs. the thicker coat from fluidized bed coating. Plastic spray booths repel powder particles. Fluidized Bed Powder Coating | Supplier. There are no common parameters in the process of fluidized bed powder coating since it changes dramatically with part thickness. We have neverRead More ….
Stratification in other powders does not show quite as easily as it does with metallics. Coating area limited to 3-4 inches above bed. Dynablue® is a low temperature (900 - 1200 degrees F) combination process with fluidized bed ferritic nitro-carburizing (FNC) & a blue oxide process. 187 Powder Painting (Air Electrostatic Fluidized-bed Coating Method). Application Methods for Thermoset Powder Coatings. The concentration of the air and powder mix can be adjusted to control the overall application performance and is one of the parameters used to control the film thickness of the coating. Acceptable to continuous length products.
Long: To boil it down, fluidized bed coating is a fairly inexpensive system that will give you virtually 100% transfer efficiency. If the oven is too hot, the bed-dipped object could cause the coating to melt off, sag, or drip. Corona gun technology has evolved greatly over the past ten years and two. In this process, the combination of the fluidized bed and electrostatic. Features include shiny, matte or foam surface finishes & resistance to abrasion, corrosion & electricity. Two, preventive maintenance is going to be your best bet when it comes to avoiding issues in this area. Kanban and JIT delivery. Fluidizing beds may not be as commonly used as they once were, but they are still a solid piece of equipment for those using them. The air causes the powder to rise and act like a fluid.
Virtually all resins with the exception of nylon can be applied easily with this process. Powder particles smaller than 10 microns are more difficult to charge successfully with a Tribo gun. The charged powder particles move with the air flow towards the earthed object. Extra beds are required for different powder types/colors. The word tribo is derived from the Greek word tribune, meaning to rub or produce friction.
Top Tip: Concerning metallics, if you are reclaiming them, you want to keep the ratio around 80% virgin to 20% reclaim to keep the color uniform. PCTM's pre-treatment options are specifically designed to give your metal object the smooth, even finish you want.
