A Beginner’s Guide To Powder Coating Systems

It also allows you to store and remove materials in a more cost effective and environmentally friendly way. Your customers will appreciate a wear and weather resistant finish, but also easy to maintain. Powder coating is a hugely popular means of painting your parts with a variety of colors and finishes available.

This allows the dust particles to charge and adhere to the metal surface during electric grinding until the powder has been gently heated and fused with the metal in a curing furnace. The most common way to apply powder coating materials is a sprayer with a dust supply system and an electrostatic spray gun. A spray booth with a dust powder coating systems recovery system is used to enclose the application process and collect dust on spray. Powder coating is a dry finishing process used to apply a dry coating material. The coating material is composed of finely ground resin particles and color pigment, along with other additives for specific functions such as gloss or hardness.

SPARTA ENGINEERING recommends almost exclusively a powder coating paint finish on all our mobile devices. We believe that powder coating is superior to paint and the best option is in price and quality. Coating our products has many advantages over applying normal wet paint. I will start by explaining the powder coating process and then describe the main benefits.

Heat the cooking oven for the best possible coverage between 300 and 500 degrees Fahrenheit. Using the oven grille or suspension grille, place the dry, powder-coated part in the oven and switch on the ventilation system. It is recommended to check the powder coating material instructions to know the recommended curing times and temperatures. For such powder coatings, film accumulations of more than 50 μm may be required to obtain an acceptable smooth film. The surface structure that is considered desirable or acceptable depends on the end product. Many manufacturers prefer to have a certain amount of orange peel, as it helps hide metal defects that have occurred during production, and the resulting coating is less likely to show fingerprints.

Anything left in your product before coating affects the adhesion and durability of the powder. You can then use various processes such as air or sandblasting to clean up waste, rust and paint from the material. The most common way to pre-treat a powder coating material is with an aerosol ring with chemical solutions.

In addition, it is not subject to irregularities, running or dripping, which are common in wet paints. The first step in one of the painting processes is to sand the product after completing production. Sandblasting is used to remove the shell from the mill, oil and oxide, which is usually supplied in newly manufactured steel. Sandblasting is used in repainted projects to remove any old coating still in the product. The medium used for sandblasting can vary greatly from biodegradable options such as walnut shells to manufactured steel sand. Most media can be reused multiple times before being removed and each has its own specific benefits and applications.

The end result of thermoplastic and thermosetting powder coatings is practically identical. In both processes, heat the powder to form the color finish on a chosen surface. Economy: The economic benefits of powder coating are many, but the biggest advantage has to do with efficiency and over-examination. The average powder coating transfer efficiency is 60-70% and each overspray is sturdy and can be practically recovered and reused without wasting the product. With liquid paint, it has a transfer efficiency of 30-35%, about 50% of the product evaporates and there is no possibility to claim overspray. The basic powder coating product is also considerably cheaper than wet paint.
