Our FF Series Drawer Magnets come standard with super-strong neodymium rare earth magnets powerful enough to capture and hold ferrous particles so small that they are invisible to the naked eye. Neodymium magnets have exceptional surface holding force for more complete removal of contaminants and less chance of “wipe-off,” referring to contamination falling off of the magnetic surface and re-entering the product stream.

Bunting’s exclusive highly refined drawer magnets are the only temperature-compensated rare earth magnets available for integration with injection molding machines. Other rare earth drawer magnets can permanently lose their magnetic power at temperatures above 175º F. Bunting’s are guaranteed not to lose magnetic strength when bolted to feed throats operating at temperatures in excess of 175º F. Magnetic energy that strong means guaranteed durability and less downtime for you – plus reduced screw wear and fewer plugged nozzles.

Bunting has a dedicated manufacturing area for FF Series Drawer Magnets, meaning that once you place your order, you’ll receive your equipment fast. With more magnetic drawer filters on plastic processing equipment than any other brand, our magnetic protection for plastics processors is the industry standard the world over.

Bunting FF Drawer Magnetic Separators are simple, heavy-duty, and long lasting. Protect your plastics application.

Short Leads-FF Series Drawer Magnets-Bunting-Newton-Magnetic SeparationDurable Construction

Bunting NEO FF drawer magnets feature rugged 11-gauge stainless steel housings built to support symmetrical compression loads of 10,000 pounds. The drawer gasket on these magnets are cut from Ethylene Propylene Diene (EPDM), which resists heat aging, is compression set, and is much more durable than sponge rubber.

• The NEO FF drawer utilizes temperature-compensated rare earth magnets for superior high-temperature operation.

• Units are built with welded stainless steel housings for easy cleaning and durability.

• EPDM gasket resists heat aging and compression set.

• High-torque nylon knobs resist breakage.

• Our patented No-Spill™ Slide Gate is fitted with a magnetic safety latch to prevent accidental closure in high-vibration applications.

• Stainless steel center drawer guide simplifies removal and re-installation of the magnet drawer for quick, easy cleaning.

• Most powdered colorants and resins slide off without sticking.

• Superior cartridge geometry increases reach-out and holding power.

• Robust construction prolongs cartridge life.

     Additional Models To Fit Any Application

  2. FF350 High-Temp FF Drawer Magnet

    Rated to 350° F for high-temp processing

    FF 350 High Temp Drawer Magnets-Magnetic Separation Drawers-Bunting-NewtonThe FF350 high-temp drawer magnet answers the growing demand by OEMs and end-user customers to process material at higher temperatures. Higher temperatures improve plastic clarity and performance, particularly in injection molding, and the Bunting FF350 ensures this higher level of product integrity

  3. We took care to maintain magnetic strength under increased temperatures and incorporated other high-temp features. For example, along with the magnet upgrade, we replaced the standard Lexan viewing window with polycarbonate. Even the plastic knobs are rated for higher temperatures.

  4. The FF350 can be used in any existing plastic molding or extrusion application. Since the housing for the FF350 matches the profile of the standard model, drawers and other accessories can be purchased separately to upgrade FF Drawer Magnets already in use.

     

  5. Select Features:
    • Equipped with high temperature-compensated rare earth magnets.

  6. • Drawer gasket: Viton sponge material rated to 400° F maximum temperature to resist heat aging and compression set.

  7. • Drawer front constructed from Polysulfone material resists temperatures up to 350° F intermittent temperature operation.

  8. • High-torque nylon knobs resist breakage at temperatures up to 350° F.

  9. • Rugged, easy-to-clean 11-gauge stainless steel housing built to support symmetrical 10,000 lb. compression loads.

  10. • Stainless steel center drawer guide simplifies removal and re-installation of the magnet drawer for quick, easy cleaning.

  11. • Superior cartridge geometry and construction increases reach-out and holding power while maximizing cartridge life.

  12. • High-temperature parts are completely interchangeable with the standard FF Drawer Magnet.

    Self-Cleaning FF Drawer Magnets – Manual and Pneumatic

    Manual & Pneumatic

    With no need to pull apart components for cleaning, our advanced self-cleaning drawer magnets feature extra-long magnetic cartridges that fit inside stainless steel sleeves. This enables a self-cleaning mechanism as tramp metal collects on the sleeve surfaces, then falls from the sleeves when they are pulled clear of the magnetic cartridges. No wiping or brushing is required, simply remove the drawer assembly and pull out the magnetic cartridge. With one smooth motion, a separate assembly cleans the magnetic cartridges with grommets, wiping the metal from the tubes to a tray resulting in less product loss.

     

  20. Select Features:
    • Features rare earth magnets to endure high temperatures without losing magnetization.

  21. • Customizable design allows drawer to fit most machine openings.

  22. • Welded stainless steel housing for easy cleaning and durability.

  23. • Detachable tramp tray alleviates messy cleanups and spills.

  24. • Pneumatic self-cleaning option also available, with the additional benefit of offering control packages for hard-to-reach installations.

  25. • Top slide gate and bottom transition are custom-made to your requirements
