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 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.
FF350 High-Temp Drawer Magnet
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.
Within the rugged housing,
the design team made a number of changes.
Polycarbonate is suitable for working temperatures of up to 130° C and
replaced the standard Lexan used for the viewing window. The easy-release, high-torque door knobs are
suitable for temperatures up to 175° C.
The housing is built to support symmetrical 4500kg compression loads and
stainless-steel centre drawer guides make removal and re-installation of the
magnet drawer for cleaning quick and easy.
The FF350 drawer
gasket is made from Viton sponge material, which is rated to 200° C maximum
temperature and resists heat aging and compression set. Polysulfone material is used on the front of
the FF350, resisting intermittent temperatures up to 175°C.
A key feature of
the new design is the ability for customers to easily upgrade existing
units. The design of the FF350 housing is
the same as a standard model, and existing users can purchase drawers and other
accessories separately to upgrade their FF Drawer Magnets into a FF350.
The FF350 is a valuable addition to the FF Drawer Filter Magnet range.
