ALNICO MAGNETIC
Developed in the early 1940%u2019s, the Alnico (aluminum, nickel, cobalt) family of magnets remains the material of choice for many applications. Its excellent linear temperature characteristics, high magnetic flux density, and good corrosion resistance are ideally suited for use in products of all sizes - from miniscule cellular telephone magnets weighing less than a gram to radar focusing magnets weighing 50 pounds or more.
BONDED MAGNETS
Polymer bonded magnets have opened a new world of application opportunities. Thermo-elastomer and thermo-plastic resins can be compounded with a variety of magnetic powders to form Injection Molded, Compression Bonded and Flexible Calendered products. Injection molded magnets can be formed into complex shapes and molded directly onto other components reducing assembly costs. Compression bonded magnets, while of simpler geometries, offer higher magnetic output. Flexible sheet and strip is used in many applications including small motors, flexographic (professional printing) devices, magnetic filtering, and signs. |

PERMANENT LIFTING MAGNETS SUPPLIER
Dust- and waterproof permanent lifting magnets can work outside in any weather.
Permanent lifting magnets don't need power supply units, magnetization and demagnetization occur due to turn of the handle.
Lifting magnets have small overall demensions and weight in comparison with electromagnets.
Magnets can keep cargo indefinitely long. They are served by one person and have a threefold capacity margin from nominal. |

Grid magnet for bulk materials
Permanently magnetic grid industrial magnets can be supplied in circular, rectangular or square format and are therefore universally applicable. Ferrous particles are filtered out from bulk material as they pass through the magnetic grid.
Advantages
Powerful magnets remove even low magnetised stainless steel particles from the product flow. |

BAT GRIP
3 Ton capacity permanent-electro lifters with battery.
Equipped with a professional remote control, this lifter is capable to be used for a long period independent of the power source (est 7
days), because the energy is only used for a fraction of a second during the MAG/DEMAG phase. |
|
Features:
Cold Operation
Since the electrical current is only used momentarily, no insulation or coil failures are caused by internal heating.
Safer Holding
The permanent magnetic material is unaffected by external power failure. Since Electro-Permanent magnets require electricity only to activate the magnet "on" or "off", there are no mechanical parts that could accidentally stick. Once the magnet is "on" the electricity can be disconnected indefinitely without any interruption to the holding power.
Cycle Time
Energizing the magnetic material typically takes 2-3 seconds.
Power Consumption
Operating costs are very low compared to conventional electromagnets because the power is applied for a minimal time. |

This universal workholding professional chuck offers maximum effective holding on the widest range of workpiece shapes and sizes. Its effectiveness is considerably enhanced by the new low profile feature, which adds more head room under the professional wheel. Only 3 1/2" in height, this new low profile interloc is 1 1/8" shallower than the conventional Walker Interloc and a full 1 1/2" less than competitive units of the same type. This savings in height permits greater flexibility with added head room under the wheel to position the work or handle bulkier pieces. This results in savings in set up time and added productivity. It also reduces the chuck weight by 30% or more.
The low profile is achieved with no loss of strength, precision or holding power. With the unique Walker Interloc design, more than 75% of the chuck's surface is major north or south poles, making it easier to locate workpieces without concern for locating poles. There is no wear loss due to the shallower polarity pattern in the replaceable top plate. |
