The complete line of Winkle (link to www.winkleindustries.com) scrap handling magnets, now called OptiMag, has been redesigned and additions have been made using new proprietary engineering software to achieve lighter weights, increased lifting capacity and lower costs for recyclers and steel mills, according to a press release issued by Winkle, which is based in Alliance, Ohio.
Winkle’s director of engineering and production, Paul Predagovic, credits the use of advanced design software developed by the company’s in-house engineering department for what the company calls significant across-the-board design improvements and additions. “Refining our magnet modeling software was a big first step in this project,” Predagovic states. “Then we applied the new design parameters to every scrap magnet in our catalog, with great results.”
The new Winkle catalog provides basic specifications for all scrap magnets. The line-up includes both cast and fabricated casings, aluminum and copper coils and ranges in size from 30 inches to more than 100 inches in diameter as well as a full range of rectangular and octagonal magnets. The scrap magnets are designated according to their design type and are engineered to achieve optimum lift-to-weight ratios and superior duty cycles without sacrificing strength and durability. Winkle also designs and manufactures specialized lifting magnets for specific customer requirements.
The OptiMag lifting magnets are engineered and manufactured using strap-wound deep-field and extra-deep field coils in Winkle’s facility. “Our engineering software allows us to design strapped wound coils with the accuracy that’s needed to manufacture the coils efficiently,” Predagovic explains. “Wire-wound coils are more costly to produce and repair. We have optimized our magnet designs so our customers can have long term sustainability and a cost effective rebuildable product.”
Winkle says it has a long history of rebuilding and rewinding all makes and models of electromagnets, including units for separation and brake coils for magnetically driven crane brakes. For scrap recyclers, Predagovic says his rebuild capabilities can reduce costs associated with rebuilding strap-wound magnets by cleaning and recovering conductor from the used coil.
“This is where our engineering capabilities really shine,” says Predagovic. “Not just designing the right magnet for the job, but designing the right long-term solution for the customer.”
