Bunting - Model FF Series -Drawer Magnets

For over 50 years, Bunting’s FF Series Drawer Magnets have been known in the plastics industry for their ability to deliver superior magnetic separation. Bunting pioneered this groundbreaking piece of magnetic separation equipment in 1966. Today, Bunting’s FF Series Drawer Magnets remain the plastic industry’s most popular choice for extrusion, injection, and blow molding equipment. Designed with the unique needs of the plastics industry in mind, Bunting offers several different models of FF drawers to suit a wide variety of applications. All of our FF Series Drawer Magnets are FULLY customizable. Whether you are working in injection molding, extrusion, or plastics recycling, we can provide you with a custom product to suit your exact needs.

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.

Durable 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.

Drawer Magnet Options (Available for all FF Drawers):

1. No-Spill™ Slide Gate 
   Patented design allows for complete shut-off of product flow, reducing spillage.
2. Purge Hopper
   Speeds cleaning of your equipment when changing color or compound without sacrificing magnetic protestation.
3. Dump Tube
   Allows operator to completely empty the drawer housing and material hopper of plastic after job is completed.
4. Liquid Port 
   Promotes quick addition of color additive into the resin. Port may also be used to hold temperature probe.
5. Powder Seal Kit
   Provides a compression seal around the Slide Gate to prevent leaking of powdery materials.
