Ervin’s Amapure eliminates contamination from 3N Lakering’s surface preparation process

Ervin, a leading manufacturer of steel and stainless steel cast abrasives since 1920, has set the industry standard through continuous innovation and an unwavering commitment to quality. Let's explore in this article a real-world example of the company’s expertise at work: the collaboration between Ervin and 3N Lakering.

Located in Thisted, Denmark, 3N Lakering is a complete solution for powder-coating steel structures. The company takes pride in its in-house pre-coating process, which includes shot blasting to ensure a perfect surface for powder coating. 3N Lakering has also built a strong partnership with Clemco Denmark, the local distributor for Ervin. This partnership ensures 3N Lakering has access to the latest advancements and best practices in powder coating.

The challenge

3N Lakering aimed to improve the efficiency of its shot blasting operations, both by automated machinery and by airblast equipment. A significant hurdle to face in achieving this goal was the presence of oil and grease contaminants within the blasting media. 3N Lakering understood from experience that even minor traces of these contaminants could significantly compromise the adhesion of the powder coating.

The solution

The first attempts of 3N Lakering at removing grease and oil from the operating mixture were by additives and produced some results. However, 3N Lakering desired a more effective solution to improve quality. Following Clemco Denmark's recommendation, the company implemented Amapure – a mineral additive to clean the metallic abrasive - into its blasting systems. This switch marked a significant breakthrough, enabling 3N to consistently achieve a clean blasting media across all its equipment.

The result

Amapure swiftly surpassed previous additives used by 3N to combat oil and grease contamination in its blasting systems.

"Previously, we required 60% more additives," explains Allan Pretzmann Jensen Production Manager, 3N Lakering. "Amapure has resulted in substantial cost savings on our purchases, and we spend less time refilling and monitoring the dosing system. The switch has brought numerous benefits. Overall, Amapure saves us time, effort, and money."

Overall, Amapure delivered a range of clear advantages:

• 
  - Amapure keeps the operating mix clean for longer periods, reducing maintenance and downtime.
  - Amapure's effectiveness allows for a significant reduction in cleaning time per workpiece.
  - The combined benefits of faster cleaning and a longer-lasting clean mix translate directly to shorter overall production times.
  - Amapure requires significantly less product compared to previous additives, resulting in cost savings.
