From large projects to small production runs, selecting the appropriate metal casting process to achieve the desired design can be difficult. MetalTek focuses on three primary metal casting processes: centrifugal casting, sand casting, and investment casting. Each comes with numerous design considerations ranging from overall shape to surface finish to dimensional tolerance. This article focuses…

When a North American manufacturer considers where to source metal castings, the choice typically involves domestic sourcing (North America) versus international sourcing (outside North America). There are several considerations when making this decision as a customer. These considerations can range from cost to the overall nature of the supplier relationship. The choice is not typically…

This case study featured a duplex stainless-steel suction press roll shell custom manufactured by Sandusky International for a papermaking machine application. Beginning with a customer-approved drawing, we developed a manufacturing plan. After centrifugal casting and heat treating the suction press roll shell, made from duplex stainless steel “Alloy 86“, we used a combination of machining…

There is a significant difference among suction roll shell alloys. When properly selected, the material will withstand the aggressive corrosive attacks of white-water chemistry and temperature, felt cleaning chemicals, machine speed, roll load, and cyclic stresses of operation. Sandusky brings you more suction roll shell specific manufacturing and metallurgical experience than any other company in…

Prices of materials such as copper and nickel continue to rise and pressure lead times. Thankfully, the centrifugal casting process is here to help buyers mitigate against this curve and protect their supply chains. For diameters of 14” (355 mm) or more it makes sense to use centrifugal castings from MetalTek instead of forgings, especially…

Tooling is critical to the different metal casting processes that MetalTek uses to manufacture components for the world’s most demanding industries such as aerospace, defense, and petrochemical. Our metal castings must be efficient, precise, and innovative. They simply cannot fail – even in high-heat, high-wear, and high-corrosion environments. Metal casting involves pouring molten metal…
