Powder Coating Explained

Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat.

Versatility

The finish is harder and tougher than conventional paint. The process is useful for coatings on metal used in many household appliances, aluminium products and automotive parts.

Durability

Aluminium or steel which has been powder-coated is highly resistant to wear and tear. The coating is resistant to chipping, fading, scratching and corrosion. This durability makes it well-suited for parts that come into contact with sunlight and other environmental factors.

Maintenance and aesthetic appeal

Powder-coated parts are easy to maintain over long periods of time. The range of colours and finish will ensure that the part you powder coat will maintain its appearance for a long time.

Eco-friendliness

Powder coating applications are non-toxic and less flammable than wet paint finishes.

Pretreatment Services

Currently available for small components

Powder coating provides greater protection and a more aesthetic finish to aluminium and steel. It also reduces susceptibility to damage, rust and corrosion which will ultimately increase a part or components lifespan and range of use. To do all of this, it is imperative to follow the correct pretreatment process to ensure the surface is clean and so the powder coating bonds more effectively to the metal.

Sandblasting Pretreatment (Bead Blasting)

Bead blasting is an abrasive cleaning process that involves smoothing and cleaning aluminium or steel by forcing tiny bead particles at high velocity against the surface using compressed air. Bead blasting is one of the most versatile pretreatment steps that can be followed before the anodising or powder coating process is applied to metal.

This process ensures the surface finish isn't impaired by marks or contaminants which can range from small scuff marks to unwanted material on the surface. Bead blasting can also remove paint and rust from the surface of the material before, and ensure it retains its durable finish after anodising or powder coating.

Soda or Vapor Blasting Pretreatment

Soda blasting or vapor blasting is a non-abrasive cleaning method that also uses compressed air but is different to bead blasting in that aerosolised particles of sodium bicarbonate (baking soda) mixed with plain water is used instead of tiny solid particles. Soda blasting is particularly effective at removing things such as light rust and old paint before surface finishing takes place.

Vapor blasting is a process that can be used to improve the overall quality (look) of the material. The size of components cannot exceed 800mm x 800mm x 800mm.

Tumbling Pretreatment

Tumbling is a process that is used when small components are places in a circular vibrating drum that is filled with abrasive beads. This process is used to remove any unwanted material particles from the original component and polishes the surface providing a smooth finish to the material.

Our tumbling machine can accept components in small quantities and sizes, for example, small door handles.
