Applying powder coating

Powder coating is traditionally applied via spraying the powder particles with an electrostatic gun, also known as a corona gun.

The electrostatic gun will impart a positive electric charge to the powder, which then proceeds to be sprayed onto an object by compressed air or mechanical spraying, then accelerated toward the piece via a powerful electrostatic charge.

Depending on the size and shape of the piece that is being powder coated, a different nozzle will be used in electrostatic coating. Once the powder has been applied it will then be heated - this is a vital step in the powder coating process as the particles will melt into a uniform film, and then cooled until hardened.

An alternative application method is called the fluidised bed method; this sees the substrate being heated prior to being dipped into an aerated, powder-filled bed. The powder will cling to the object and melt. There will be another round of heating that is required in order to finish curing the coating. This is actually how many dishwasher racks are coated.

Powder Coated Aluminium Surface: long life and environmental durability

Vertik-al work in partnership with our clients ensuring we improve our environment rather than change it. Our long term strategy is to continue to develop and improve the services we currently offer and be at the forefront of technological advances within the powder coating industry.

In our aesthetically driven world it is important for every aspect of our lives to look as best as it can possibly be. One small way to achieving it is powder coating. Powder coating is an effective technique used to applying a protective or decorative coating to most metals, which might be used in a wide range of consumer or industry applications. The ease and durability of powder coating has made this technique a favourite choice of many industries as a high quality finishing surface. That is the reason why Powder Coating processes are in great demand by wide range of consumer or industry that produces diverse kind of products. Vertik-Al is a world class provider of aluminium powder coating products such as extrusions, cladding and rainwater goods for the architectural industry.

Materials can be exposed to a great many things; and this exposure can cause varying effects. In order to prolong the life of the day to day objects there are various additives used. These additives play an important role as they are on to save your well earned money and reduce the waste too. The process of Powder coating is mainly to increase durability and give an aesthetics looks to the object. The available materials undergone through these additives make the object more presentable. To have a perfect finishing touch, this process can be applied to cladding, rainwater goods and aluminium extrusions – representing a  wide range of consumer and industrial applications. Powder Coating is one of the most widespread methods of surface coating and provides an almost limitless choice of colours with excellent repeatability of colour matching.

Powder coating gives the industries one of the most economical, long lasting and colour durable quality finishes available on any type of metal. It is particularly used on aluminium, as aluminium is found in abundance and for various reasons is extensively used in various industries for manufacturing goods. If you use powder coating technique on aluminium metal, Powder Coated Aluminium surface is more resistant to chipping scratching, fading and wearing than other finishes. This increases the life of the product. With numerous colour schemes available, colour selection is almost unlimited. As the colours applied with the help of powder coating stay bright and vibrant for a longer duration, it tends to be cost effective. Texture selections range from smooth surfaces to wrinkled or matte finishes and rough texture designed for hiding rough patches, and adding the décor of the object.

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 is that the product results are superior when aluminum and metal are used, compared to other materials.  Vertik-al are striving to reduce our carbon foot print on the environment. Strategic improvements are in place to upgrade our plant as we work into the future. Our policy to minimise or recycle waste continues.

All polythene and cardboard packaging is recycled, water and energy usage is continually monitored to minimise and conserve. Our electrical motors are currently in the process of being changed to VSD energy efficient drives, our fleet of vehicles have the latest most fuel efficient engines available today all leading to an efficient and environmentally friendly company.  Vertik-al are also looking at new Chrome free pre-treatment systems to help promote a greener, more environmentally friendly process, these products are currently being tested.

The Vertik-al powder coating process

The selection of powder coating technology offers the consumer an alternative to liquid coatings that is economical, efficient, and environmentally friendly. It produces a high quality finish and is available in a huge  range of colours, glosses, and finish textures.

The Vertik-al powder coating process is very simple - a suitable formulation is developed as a finely ground powder; the material is then sprayed on the surface to be coated as a thin layer held in place by static electricity. The part is placed in an oven to melt the powder which then flows and fuses into a continuous coating which is very hard and has no porosity. Because powder coating does not use solvents there are no chemicals released into the air. Over spray powder is captured in dust collectors and may be reused or baked to render it inert and disposable.  We are proud to work in partnership with our clients ensuring we improve our environment rather than change it.

Superior finishes combined with durability reduce maintenance and extend the life of coated products. Many product manufacturers are enjoying the top quality offered by powder coating. Auto parts are seeing the application of powder coating where a protective as well as decorative finish is desirable. The chip resistance and durability of powder coating is particularly beneficial in the harsh conditions endured by suspension parts.  Harley-Davidson motorcycle frames have all been powder coated at the factory since 1987.

Building products such as aluminum extrusions used for window and door frames are another area taking advantage of the durability of powder coating. Vertik-Al is a world class provider of aluminium powder coating products such as extrusions, cladding and rainwater goods for the architectural industry.
