In the production or repair of metal components, the choice of finish can significantly impact their visual appeal, sturdiness, and ability to withstand factors such as humidity. Two commonly employed techniques are sandblasting and powder coating, each offering distinct benefits. It is not uncommon to use a combination of both approaches. Below is a summary of each method that you should be aware of.

What is Powder Coating?

Powder coating is a technique that enables you to apply a coating similar to paint on a metal component. Nonetheless, the coating has a more uniform thickness and a smoother surface compared to paint, and unlike paint, the method doesn’t necessitate the use of liquid solvents.

To achieve this outcome, your service provider will ground your component in an appropriate setting, ensuring that the electric current passing through it reaches the ground. Subsequently, a unique spray gun will be employed to apply dry powder over the component. The minute particles of powder carry an electric charge and are drawn towards the grounded part, bonding with its surface upon contact. The coating can be glossy or matte and is available in a wide range of colors.

What is Sandblasting?

Similarly, sandblasting utilizes a spray of minute particles; however, instead of using a microscopic charged coating material, it employs hard fragments like silica sand, copper, or walnut shell. The sandblasting equipment projects these particles with immense force, enabling them to abrade and, in some cases, even etch the metal surface, depending on the type and fineness of the material utilized.

For certain metal components, an etched surface or a blend of smooth and etched designs might suffice as a finishing touch. However, sandblasting is frequently a necessary interim procedure. The abrasives can eliminate rust, corrosion, old paint, grease, and other impurities from the metal surface, readying it for powder coating. Attempting to coat a surface that is dirty or corroded will cause the coating to bubble and crack.

Why Sandblasting is Necessary for Pretreatment before Powder Coating

Below are a few benefits of utilizing sandblasting:

• Efficiency – Sandblasting is remarkably swift and can proficiently clean the surfaces.
• Rust eradication – When rust starts corroding metal, it spreads rapidly, posing a risk of irreversible harm. Sandblasting can eliminate rust thoroughly while preserving the metal’s structural stability.
• Eco-friendliness – Sandblasting primarily entails blasting abrasives onto surfaces, eliminating the risk of inhaling or releasing any hazardous gases.
• Exceptional outcomes – Sandblasting is applicable to virtually all surface types, delivering an immaculate finish every time.
