New High Temperature Drawer Filter Magnet

Bunting is launching the FF350, a new Drawer Filter Magnet designed for use in high temperature applications, at the K2019 Show (16-23 October 2019 Dusseldorf, Germany).

The New FF350 Drawer Filter Magnet

Bunting is one of the world’s leading designers and manufacturers of magnetic separators and metal detectors for the recycling and plastics industries. The Bunting European manufacturing facilities for their wide range of metal separation and detection equipment are in Redditch, just outside Birmingham, and Berkhamsted, both in the United Kingdom.

The FF Series of Drawer Filter Magnets collect and separate ferrous metal contamination from gravity fed, dry, free flowing materials. Mounted inside the outer housing are extremely strong Neodymium Rare Earth Magnets which attract and hold any magnetically-susceptible contamination. FF Drawer Filter Magnets are used extensively in the plastics sector prior to moulding and extrusion, and also in the processing of secondary plastic.

The FF350 High-Temp Drawer Magnet answers the growing demand from both OEMs and end-user customers for processing material at higher temperatures. Higher temperatures promote plastic clarity and performance, particularly in injection moulding. However, neodymium rare earth magnets are susceptible to permanent damage if exposed to excessive heat, significantly reducing magnetic strength and the capability to separate fine ferrous magnetic particles.

During the design phase, Bunting’s engineering team reviewed all aspects of the Drawer Filter Magnet, assessing the areas of risk when exposed to high temperatures. Magnetic integrity was vital and to maintain the magnetic strength and separation capability, the FF350 features special high temperature-compensated rare earth magnets.
