Bunting Magnetics Co. (Booth W5563) highlights the FF350 high-temperature drawer filter, one of its newest innovations.
Available for hands-on demonstrations, the drawer filter is rated to 350º F to deal with the high heat required in current molding and extrusion applications. That heat can diminish a magnet's strength and holding power.
In the redesign to accommodate higher temperatures, Bunting uses a different polycarbonate for the viewing window as a replacement for a Lexan grade of PC.
Plastic knobs for latching down the drawer can tolerate the higher temperatures.
Users can install the drawer above the opening of a molding or extrusion machine. Plastic resin passes through the drawer to remove ferrous contaminants. The filter protects the molding machine from damage due to tramp metal.
Bunting incorporates upgraded rare earth magnets allowing the FF350 to have the stronger hold and longer life.
The FF350 design fits Bunting's standard FF housing. A current user can modify existing equipment to meet changing needs.
Bunting manufactures the FF350 at its Newton, Kan., facility.
Bunting initially introduced its FF Series drawer for the plastics industry in the late 1960s.
"Innovation is one of our core values, and we are constantly evaluating our products for improvement," said Brock Herrmann, magnetic separation product manager.
Also at NPE2018, Bunting will display a grinder feeder conveyor with a metal detector and a stainless steel High Intensity Separation Conveyor.
The feeder conveyor is useful in shredding and grinding plastic purgings to scrap bumpers, stringers, carpet, wood pellets, plastic bottles, tires, glass bottles or wood pallets. The conveyor can handle 1,000-10,000 pounds per hour and uses 6-10-inch pulleys.
The HISC unit can attract, hold and extract work-hardened 300-series stainless steel metals and para-magnetic chips from a plastic product stream.
In addition to its Kansas headquarters, Bunting Magnetics has facilities in Elk Grove Village, Ill.; DuBois, Pa.; Berkhamsted, England; and Redditch, England.
