VIBRA® Hopper Magnets

High-efficiency magnetic separator grids designed to extract tramp iron from free-flowing granules in hoppers. Protects molding machines and extruders from damage.

Why Choose VIBRA® Hopper Magnets?

Designed to protect your equipment and ensure product purity in demanding industrial environments

Versatile Shape Integration

Available in round, square, or rectangular designs to fit any machine hopper. Whether for injection molding or grain storage, we custom build the grid to match your existing equipment dimensions perfectly, ensuring a seamless drop-in fit for your production line without expensive modifications.

Maximized Flow Contact

Optional rod or angle baffles are positioned strategically between magnetic tubes. These deflectors force material directly onto the magnetic surface, preventing material from “streaming” through the gaps and ensuring 100% of the product flow is effectively filtered for maximum purity.

Hygienic & Rugged Build

Constructed from fully welded 304 or 316 stainless steel, these magnets meet strict sanitary standards. The robust design withstands the abrasive wear of plastic pellets, ceramics, or minerals while remaining easy to clean and fully corrosion-resistant for long-term industrial use.

FAQs About VIBRA® Hopper Magnets

What are hopper magnets used for?

Removing tramp iron from material inside hoppers and bins.
They prevent metal from damaging screws, barrels, and molds in plastic injection molding and food processing machinery.

What shapes are available?

We offer Round, Square, and Rectangular custom sizes.
We manufacture the grid to fit the exact dimensions of your machine's feed throat or storage bin.

Do I need baffles?

Yes, if you have fast-flowing or fine materials. Baffles direct the flow onto the magnetic tubes, ensuring the material doesn't bypass the magnetic field.

Are they food safe?

Yes, sanitary stainless steel options are available. Our food-grade models feature polished welds and 316 stainless steel to comply with strict hygiene regulations.

Which magnet strength is best?

Rare Earth for fine dust; Ceramic for large parts.
Use high-intensity Rare Earth for food purity; use Ceramic for general machinery protection against bolts and nuts.

How do I clean them?

Simply pull the magnet out of the hopper and wipe the collected metal towards the ends to release it.
