Bunting® is The Leader for Metal Detection in Plastics.
For over 60 years, Bunting has been a leading supplier of high quality magnetic separation, metal detection, and material handling equipment for customers working in the many different facets of the plastics industry. Additionally, we supply the plastics industry with top of the line magnetic printing cylinders for plastic decoration. Bunting’s wide variety of magnetic separation and metal detection products help you to protect your equipment from the costly repairs associated with metal contamination. If metal contamination is allowed to persist in material, severe damage can occur to expensive specialty equipment such as blow molding, injection molding, extrusion, and compounding machines.
Magnetic Separation for diverse applications within the Plastics industry.
Bunting pioneered the industry standard FF Magnetic Separation Drawer for the plastics industry, and today we offer the greatest range of options for metal removal. No other company has the variety that Bunting does. Bunting’s magnetic separation equipment effectively removes ferrous metal contaminants from your product flow without interrupting your greater process. We offer extensive customization options, allowing us to easily meet your construction standards, facilitate easy installation, and satisfy your exact requirements. Many of the magnetic separation products we have designed for the plastics industry provide targeted solutions for industry-specific problems, such as our High-Temp FF350 Drawer, which tolerates the high temperatures associated with plastics applications such as drying hygroscopic resins.
Bunting’s range of metal detectors for the plastics industry excel at sensing and removing ferrous, non-ferrous, and stainless steel metals from your process flow. These highly sensitive metal detectors remove all sources of harmful metal contamination from your material while minimizing loss of good product. Some of the specialty metal detectors we offer for the plastics industry include: the quickTRON™ 03R for gravity-free fall applications; the pTRON™ for pneumatic conveying systems; the meTRON™ 07 CI for finished parts inspection; the SL, S,D, and C coils for shredder and grinder protection; and the MMS metal detector for molding machines.
Material Handling Conveyors
For material handling in plastics applications, Bunting offers innovative conveyors that enable you to run your operation more smoothly and safely at every point in the process. For example, our complete line of shredder/grinder feeder conveyors accommodates the many customers who are now regrinding scrap and purgings in-house. Many of our conveyors are easily paired with our metal detectors, meaning you can consolidate steps in your manufacturing process while increasing your overall product quality. Bunting offers a complete line of shredder/grinder feeder conveyors with and without metal detectors and magnetic separation to protect your equipment and purify your product along with Eddy Current Separators to further purification of PET and ground plastic.
Bunting is also well known for our magnetic printing cylinders. Our range of products includes 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 any kind of plastic container with ease. We have invested in state-of-the-art precision machinery to manufacture our magnetic cylinders to exceed OEM specifications.
Many industries fall within the category of plastics, including injection molding, plastics recycling, large-scale manufacturing, and many more. Bunting’s custom design capabilities ensure that no matter what industry you are working in, you will receive a custom designed piece of equipment that meets the exact needs of your specific application. We offer total solutions, and have decades of experience in creating the highest quality equipment.

High Frequency Eddy Current Separator
Features an optimized magnetic field, maximum gauss intensity, and intense separation power.
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 Separators come in 3 grades of Rare Earth Magnets and are self-cleaning. They provide continuous removal of ferrous contaminants from product flow.
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.
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.
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.
Cleaning systems use magnetic and electronic separators to remove both ferrous and nonferrous contaminants efficiently from free-flowing virgin resins, regrind, and recycled plastics.
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.
Permanent Drum Magnets
Permanent drum magnets are versatile, robust magnetic separators that are well suited to a wide range of applications, including those in the food, plastics, powder and bulk, grain and milling, and metal recycling industries.
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 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 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.
