Powder coating is a process where the dry powder is applied to metal surfaces using a spray gun that electrostatically charges the powder. The metal is then heated in an oven, which causes the powder to melt and form a smooth, even coating on the surface

Our state-of-the-art 7-Stage Automated Powder Coating Plant includes Oxsilan Technology Chrome-Free Pretreatment and Reverse Osmosis water treatment. For very large components, we have a powder coating batch over  8m x 2m x 2m.

Oxsilan Technology is a chrome-free pretreatment method used in metal finishing processes. It is a phosphate-free pretreatment technology that uses a combination of inorganic and organic compounds to create a nanometer-thin layer on the metal surface. This layer improves adhesion, corrosion resistance, and paint/powder adhesion and is also environmentally friendly and safe. It can be used on a wide range of metals, including aluminium, steel, and zinc-coated steel.

The Reverse Osmosis water filtration system removes impurities and minerals from water by using pressure to force the water through a semi-permeable membrane, blocking impurities and minerals and allowing only pure water to pass through. This process helps to ensure consistent, high-quality finishes while reducing the risk of contamination and environmental impact.

Powder Coating Process:

1. Pretreatment Process: use Oxsilan Technology to remove any oil, grease and other contaminants that could affect the adhesion of the powder coating.
2. Drying: dry the surface of the material via a hot drying oven
3. Powder application: powder is applied using a spray gun that electrostatically charges the powder particles, which are attracted to the grounded surface, forming a coating.
4. Curing: the product runs on a line through a heating oven and is heated to a temperature that melts the powder coating and allows it to flow and fuse, creating a durable and uniform finish.
5. Quality: the final product is inspected for defects, such as uneven coating thickness, bubbles, or cracking.

Powder coating is more durable and resistant to scratches, chips, peeling and fading than traditional liquid paint.

It is a more environmentally friendly option than traditional paint because powder overspray can be collected and reused., reducing waste.

Powder coating can be done in a wide range of colours, textures, and finishes, including matte, glossy, metallic, and textured.

SurTec 650 is a Tri-chrome passivation for Aluminium, a conversion coating process.

We have in-house SurTec 650 processing tanks where aluminium parts go through a dipping process to achieve a transparent protective coating which gives excellent corrosion protection of the aluminium surface.

SurTec 650 can also be used as a substrate for the adhesion of paints or powder.

Due to low surface electrical resistance, this process is a benchmark technology in the electronics industry.

Meets MIL-DTL-81706-B and MIL-DTL 5541-F  corrosion requirements.

Metalizing is a process of applying a metallic coating layer onto a surface of a steel component, usually to enhance corrosion resistance. This process is achieved through a technique of thermal spraying.

Zinc/aluminium wire is fed through a metalizing spray gun, where it is melted, and a thin layer of molten metal is sprayed onto the product to form the protective coating.

Before the metalizing process, the steel product must be abrasively cleaned.

Metalized surfaces are usually painted or powder coated for maximum corrosion protection

This process is suitable for steel structures located outdoors and exposed to harsh environments which are vulnerable to surface deterioration over time.

Abrasive blasting is a process that involves using a stream of abrasive materials to clean a metal surface before painting, powder coating or other surface treatment.

The process involves propelling abrasive materials at high speed against the surface being worked on.

Our industrial 9m x 3m abrasive blasting facility uses Aluminium Oxide blast media for its hardness, strength and efficient cutting and etching surface finish.

Advantages of our blasting method/media:

• Superior hardness and strength for hard substrates
• Excellent quality of surface finish
• Ability to be recycled and reclaimed for multiple passes
• Non-toxic and lower dust levels.
