Blog Sandusky International: Ready To Serve Your Pulp & Paper Application Needs

The Sandusky International division of MetalTek have been the worldwide leader in manufacturing paper roll shells since pioneering centrifugal casting more than a century ago.

For those familiar with the Sandusky name but not MetalTek, we joined the MetalTek International family of casting foundries in 2010. However, we are still the same company committed to being a leader in the pulp and paper industry by providing excellent customer service and manufacturing quality products.

Customers designing, manufacturing, or operating papermaking machinery rely on Sandusky for the world’s leading roll shells. Utilizing a deep understanding of the demanding environments in which our pulp and paper customers operate, Sandusky provides products and solutions to extend roll life and reduce operating and maintenance costs for paper mills around the world.

A Century Of Experience

Our unrivaled experience has allowed us to advance papermaking technology for over a century. These achievements have allowed us to make quality roll shells in more types, sizes, alloys, and finishes than anyone else in the business. Here are just a few milestones:

• Introduced the first practical suction couch roll for cylinder paper machines.
• Patented the first suction couch and press rolls for Fourdrinier paper machines.
• Pioneered the first commercially produced centrifugal castings.
• Sold the first centrifugally cast suction roll shell.
• Manufactured the first centrifugally cast stainless steel suction roll shell.
• Introduced the first centrifugally cast duplex stainless steel for suction roll shells.
• Introduced first Argon Oxygen Decarburization (AOD) refined centrifugally cast stainless steel suction roll shell.

The Sandusky Division of MetalTek has more suction roll shell manufacturing and metallurgical experience than any other company in the world. This provides you with flexibility and single-source convenience for centrifugally cast roll shells – ferrous and nonferrous, plain and drilled – for a wide variety of applications spanning the entire paper machine-from the wet end to the winder.
