<![CDATA[
Newton, Kansas-based Bunting Magnetics Co. is introducing a high-temperature version of its FF Series drawer magnet for the plastics industry that can perform at a drawer temperature of 350 degrees.
Bunting will debut the Hi Temp FF Drawer Magnet, the FF350m at NPE 2018 in Orlando, Florida, May 7-11. Bunting original equipment manufacturers (OEMs) and end-user customers will be able to discuss the specifications and have hands-on demos with actual drawers.
“Current equipment manufacturers of the molding machines and dryers are looking to process at higher material temperatures, and the FF 350 Hi Temp Drawer Magnet addresses these new requirements of the industry,” says Brock Herrmann, product manager, magnetic separation. “High heat can be damaging to rare earth magnets, so it’s important to balance the need to handle higher temperature plastics but retain the holding value of our magnets.”
The Hi Temp FF drawer is most often installed above the opening of the molding machine and plastic resin passes through the drawer to remove ferrous contaminants. This ensures a cleaner, higher quality product, Bunting says. It also protects the molding machine from damage arising from tramp metal.
The Hi Temp FF drawer can be used in any plastic molding or extrusion application, the company says. Because the drawer sits at the opening of the molding machine, in applications where the resin needs to be dried and/or preheated to more than 300 degrees at the introduction to the molding machine, the magnets will be subjected to higher temperatures.
In addition to the magnet upgrade, the Lexan viewing window has been replaced with a polycarbonate one that will hold up under the higher temperature conditions, Bunting says. “We thought everything through on this redesign so that even the plastic knobs that latch down the drawer are designed for the higher temperatures,” Herrmann says.
“We went further than the actual required temperature rating to make sure this design would be effective in the future,” he continues. “Other brands of magnetic separators simply won’t retain their magnet strength over time with the higher temps we are seeing in the industry. So far, we aren’t aware of any competing product that can match the temperature rating, along with the pounds holding value of our magnets.”
Because the design of the housing for the Hi Temp FF Drawer Magnet is the same as Bunting’s standard FF, the drawers and accessories can be purchased independently to complement the existing housing.
