What is Aluminum Powder Coatings?

Powder coating is applied over metals, including aluminum, to create a protective barrier that guards against rust and adds years to the metal. Untreated aluminum is not known to rust; however, it can oxidize resulting in the formation of a chalky-white substance. This is why an aluminum powder coating machine is used. The process helps reduce the risk of damage to the metal. Plus, it can be applied to a variety of metals. There are three main types of powder coatings, including thermoplastics, thermosets, and UV curable powder coatings.


Why Choose Powder Coating for Metal

Powder coating is used to prevent surfaces from sustaining damage, especially in outdoor environments. However, it is also used indoors as it prevents metal from rusting or losing its sheen. In addition, powder coating for metal helps save money as it adds years to products and offers a very high return on investment.

Suitable for All Metals

Powder coating is suitable for almost all metals, including aluminum. It is perfect for industrial parts, architectural applications, medical devices, bicycle parts, car parts, household appliances, automotive refinishing, furniture, enclosures, lighting, trailers, and more.


Powder Coated Aluminum Sheets, Panles, Windows

Powder coated aluminum involves the process of applying dry paint to an aluminum product by way of electrostatically charging the powder and then spraying it onto the product. Decoral's exclusive aluminum powder coated technology allows for detailed and vivid shapes and patterns.

Regarding coating metal, aluminum and metal materials can be decorated with various designs - from wood grain to custom picturesque compositions - by the use of powder coating of aluminium.  The result is material that is both durable and versatile, one that can be utilized for nearly any purpose. The best reason to use the powder painting process for aluminum coatings is that the product results are superior when aluminum and metal are used, compared to other materials.

Examples of powder coating aluminum products are aluminum windows for residential and commercial projects, appliances, furniture, elevator doors, decks and railings, and others.  You can even powder coat aluminum parts such as aluminum wheels if cleaned and handled properly.

Powder coating aluminum is simple to clean. This is especially true when compared to wood, because powder aluminum coatings do not require any form of painting or staining. Powder coating metal is a durable, high grade powder coating process resulting in a finished product that withstands harsh environmental conditions. These include extreme UV exposure, salt spray and heavy pollution.

Wood grain powder coating on aluminum comes in a smooth or textured natural finish and looks so realistic that you can’t believe it’s not wood.

About 90% of materials that are powder coated are steel, aluminum or metal.

Metal powder coating entails:


1.) Part preparation (pre-treatment)

2.) Application of powder

3.) Curing

Powder coating metal pre-treatment process


Prior to the actual aluminum powder coating colors step, the metal or aluminum product must be thoroughly cleaned which typically starts by removing grease and existing coatings.  It is essential to remove soil, metal oxides, oil, lubrication greases, etc. before moving forward with the metal powder coating process.  It is accomplished by using any of a variety of chemical and mechanical methods, which depends on the product's size and material, the type of material to be cleaned and the expected function of the finalized product.  Different powder coating applications may require alternate preparation methods, which may include abrasive blasting.


Powder coating aluminium processes


Next in the powdercoat aluminium process, after the pre-treatment step mentioned above, the product is then placed in advanced decoral aluminium powder coating machine and the powder particles melt and coalesce to form a continuous film.  The powder treatment will effectively apply the design chosen to use.  One can then create a design of choice by selecting from a variety of powder-coated aluminium colors and powder coating patterns.

Commonly, the powder coating is applied to metal objects like powder coated aluminum windows, powder coated aluminum door by spraying via an electrostatic gun. This tool adds a positive electric charge to the powder, which is then applied via spraying (using mechanical or compressed air) in proximity of the grounded object. Motivated by the electrostatic charge, the spray accelerates toward the product, which is then heated. As a result, the powder melts into a uniform film before being cooled to form a hard coating. Alternatively, one may heat the metal and then apply the powder onto the hot substrate by spraying. This method creates a uniform finish, resulting in the finest of aluminium coating process.

Powder coating metal curing process


The powder-coated aluminum cure process requires a specific temperature for a specific duration to achieve full cure and establish the full film properties for which the material was designed. The curing schedule and process could vary according to the manufacturer's specifications of the product being cured.  It also depends on the finish and level of dye, aluminum wood grain for example.
