The Great Irony: Big Box Stores Use American Magnetic Sweepers but Sell Imported Version

Magnetic Sweepers are used in many, many industries for a multitude of purposes. One of the more interesting uses is in the distribution facilities of the nations’ big box stores.   Aside from visiting their local big box store for discounted, cheap goods, most people don’t think about the process of getting the items to the […]

Unusual and Unknown Uses for Industrial Magnets in the Food Industry

It never fails to amaze us at the broad spectrum of customers coming to us for magnets.   Just when we think we’ve run out of new industries to cater to,  we get another call for a use which probably no person other than the guy on the other end, would be familiar.  We all know […]

Industrial Magnets

Industrial magnets come in many forms.   Fifty years ago, the most widely used material to construct industrial magnets was ferrite.  The problem with ferrite is that it is very brittle and shatters easily.  Engineers subsequently began using a combination of aluminum and nickel.  Most recently, rare earth magnets have become quite popular and common for […]

FOD Magnets and Maintenance Costs

The damaging effect of F.O.D. (Foreign Object Debris) on maintenance costs is substantial. For example, the cost to repair a FOD-damaged engine will easily exceed one million dollars. FOD also causes extensive indirect costs including but not limited to:

Flight Delays and Cancellations, which Translates into Lost Revenue and Customers
Excess/Additional Work for Airline Management and Line […]

Magnetic Sweeper Housing Replacement

While magnetic sweepers are constructed of 6063T5 Aluminum Extrusions, the lightest, strongest grade of Aluminum Extrusion available for the purpose, there are times when we are asked if these housings can be replaced rather than purchasing a new magnetic sweeper.

While suggested suspension height for the magnets is approximately four (4) inches, at times these […]

Magnetic Separators & Tri-Polar Magnetic Circuitry

Tri-Polar Magnetic Circuitry is new and revolutionary for use in Magnetic Separators and Cross Belt Magnets. It is the ultimate in Permanent Magnet technology, not available from any other magnet system manufacturer in North America. Shields Company Magnetic Separators and Stationary Separators utilize this computer designed circuitry using a large and costly 13-Ton Magnetizer, one […]

In Layman’s Terms: Permanent Vs. Rare Earth Magnets

A lot of confusion arises from buyers of magnetic sweepers and industrial magnetic products regarding the difference between “Rare Earth” and “Permanent” magnets. Technically, Rare-earth magnets are permanent magnets. The primary difference being that rare-earth magnets are made from alloys of rare earth elements while other permanent magnets are ferrite or alnico.

When manufacturing permanent […]
