If we optimise part of our process, we can share the benefit of that with our customers.

ESAT VURCAK
FOUNDER AND CEO – E.V.C.

Ervin produces stainless steel shots, and offered to run some blast trials for E.V.C. at our Sprockhövel plant. The results were very positive, with the class leading chrome-nickel shot AMACAST, allowing a better cleaning performance, shorter cycle times and consumption savings of approx. 20%.

Result

The excellent results obtained in the blast trials were confirmed during a controlled trial under normal production conditions. The stainless steel shot used in the hanger type shot blast machine has been replaced by Ervin AMACAST, and the foreseen savings have been confirmed. The lifetime of the Ervin product is more than 20% higher, and the quality of the blasted surfaces significantly better. The reason is the unique production process of the Ervin AMACAST stainless steel shot. AMACAST is atomised in a controlled atmosphere in a dedicated plant. All the parameters of the operation (atmosphere content, flow, speed, size, cooling cycle, shape, etc…) are fully computerised. Ervin also introduced the high performance chrome alternative AMACHROME, which has helped optimise cost savings even further.

  • Increased abrasive life of 20%
  • High quality blasted surfaces
  • AMACHROME introduced to site
