Plastics
Bunting® is The Leader for Metal Detection in Plastics.
Bunting® is a leading manufacturer of magnetic technology products for various industries. The Plastics Industry specifically uses our Magnetic Separation Systems, Metal Detection Equipment, Material Handling Conveyors, and Magnetic Printing Cylinders for plastic decoration. Our products can help protect your equipment from costly repairs on your blow molding, injection molding, extruding and compounding machines.
We manufacture magnetic equipment for diverse applications within the Plastics industry.
Magnetic Separation
We manufacture an extensive line of magnetic separation equipment to remove metal contaminants. They can handle a broad range of applications with exceptionally thorough removal of metal tramp. We can meet your specific construction standards and customize to satisfy your special requirements.
Metal Detection
Our Metal Detectors sense and remove the presence of ferrous, non-ferrous and stainless metals in the process flow. They are highly sensitive pieces of equipment, and should be protected from environmental interference. Successful detection and separation of metal will protect your processing equipment from damage.
Material Handling Conveyors
Innovative conveyors will enable you to run your operation more smoothly and safely at every point in your process. Many companies are regrinding their scrap and purgings in-house. Bunting provides a complete line of Shredder/Grinder Feeder Conveyors with and without Metal Detectors to protect your equipment and purify your product.
Magnetic Cylinders
We produce a wide variety of magnetic cylinders for the printing industry including magnetic die cutting cylinders, two-piece can printing cylinders, plastic decorating cylinders, and corrugated carton printing cylinders. Our magnetic cylinders can be used to print on food containers with ease. We have invested in state-of-the-art precision machinery to manufacture our magnetic cylinders to meet or exceed OEM specifications.

FF Series Drawer Magnets
FF Series Drawer Magnets are built with strong Rare Earth magnets for strong holding force in gravity flow applications. They are temperature compensated with stainless steel construction and designed for the Plastics Industry.
Drum Magnet
Drum Magnet Separators come in 3 grades of Rare Earth Magnets and are self-cleaning. They provide continuous removal of ferrous contaminants from product flow.
Cleaning Systems
Cleaning systems use magnetic and electronic separators to remove both ferrous and nonferrous contaminants efficiently from free-flowing virgin resins, regrind, and recycled plastics.
In-Line Magnets
In-Line Magnets are for Gravity or Pneumatic flow applications. Enclosed pipe systems for unobstructed product flow. Rare Earth Magnets are standard. For all industries.
HISC® High Intensity Separation Conveyor®
Designed for extreme high gauss fields of magnetic separation of work hardened stainless steels and removal of lightly magnetic tramp metal fines.
Eddy Current Separator
The Eddy Current Separator core is designed to provide a high level of gauss intensity to enhance separation on a wide range of nonferrous conductive materials and sizes. It is protected with the tough urethane belt and a fiber shell. From aluminum cans to aluminum flakes, our ECS units do an excellent job of throw and separation.
Cross Belt Magnets for Conveyor Separation
Continuous over-conveyor separation for the recycling industry to remove ferrous materials from non-ferrous materials in plastics, wood, tire, metal and municipal scrap recycling.
Shredder Feeder & Discharge Conveyors
Grinder Feeder Conveyors can be used to protect your Shredder from being damaged by separating out the metal contaminant with a magnetic cross-belt or metal detector before the product is transferred to a shredder, and Discharge Conveyors can purify your product on the way out.
DragSlide Conveyors
DragSlide conveyors are totally enclosed and use UHMW drag flights in a chain conveyor design to move and convey film & fiber materials within a sealed conveyor. This makes for a much cleaner facility allowing you to use your employees for production versus clean-up maintenance.
Bale Inspection Conveyors
Bale Inspection Conveyors with metal detectors provide inspection for baled recycled materials. Can be used as either a stand-alone conveyor or as an in-feed conveyor to the shredder line.
Bale Break Conveyors
Bale Break Conveyors break up bales of recycled plastic bottle containers. Heavy-duty construction for rigorous applications. Designed to improve loading and separations efficiency with recycled materials.
Plate Magnets
Plate Magnets capture fine metal particles from chutes, suspended in powdery, moist, clumpy, abrasive or bulk materials. Various models available. For all industries including, Food, Powder & Bulk, Grain & Milling, Recycling and Plastics.
Trough-Belted and Transfer Conveyors
Horizontal and inclined regrind or pellet transfer conveyors in any size your application requires. Various belt styles including smooth flat flexed wall, cleated or cleat topped belted conveyors to transfer bulk material to a Granulator or storage facility.
Magnetic Cartridges & Grate Magnets
Grate Magnets and Magnetic Cartridges are engineered to achieve balance between reach-out and holding force. Can be used in all industries.
Torpedo Magnets
Torpedo Magnets are used in “Just-in-Time” hopper loaders. They protect plastic molding machines by capturing tramp metal before entering machine. For the Plastics Industry.
Magnetic Pull Test Kits
These test kits has been developed for the purpose of field inspection, measurement and performance analysis of permanent magnetic separation equipment to guard against a lapse in magnetic protection.
Gaylord Cleaning Station
The Gaylord Cleaning Station combines a Bunting drawer magnet with an electronic metal detector to remove ferrous and nonferrous contaminants.
Metal Detectors for Conveyors – Recycling and Plastics
Our metal detection equipment works in conjunction with our conveyors to protect your product and equipment from damage. For under-the-belt and over-the-belt conveying for product inspection.
Pneumatic Style Metal Separators
These metal separators detect and reject all metal types in enclosed pipe systems. Easy operation, fast-acting reject flap, and maintenance-free.
Magnetic Separation Pulleys
Offering superior continuous removal and discharging of ferrous contamination like nails, staples, bolts, and wire from conveyors, all with maintenance free operation.
Metal Detector For Film, Web, or Textile Applications
These Flat Coil Detectors prevent costly repairs and production downtime. Units are self-monitoring for added reliability. The ProfiLine features advanced circuitry which reduces false signals and product waste.
Gravity Free-Fall Style Metal Separators – Recycling and Plastics
Automatically detects all ferrous and non-ferrous metals without process interruptions by separating contaminated materials from product flow.
Move-IT™ Systems
Move-IT™ Conveyors are built to order but priced like stock, available in the most common conveyor sizes and can be custom ordered in a wide range of lengths and widths to fit your application.
Mattop Belted Conveyors
Usually designed for specific applications where the smooth top surface of a mattop belt has advantages over a fabric belted conveyor. Mattop belted conveyors are easier to slide parts across the belt and are better for accumulation applications.
