| The most strength magnet materials available nowadays. Because of their powerful and good demangetization resistance, smaller magents can be used to get the same energy, therefore it contributes to the development of many small and flat moters used in the high-tech industry. However, neodymium magnets have to be plated to against rusted and should not be used at extremely high temperature. |

PERMANENT LIFTING MAGNETS
Dust- and waterproof permanent lifting magnets can work outside in any weather.
Permanent lifting magnets don't need power supplies, 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. |

Specification of magnet:
Sintex supplies customer specified magnets i.e. magnets manufactured according to a customer drawing or sketch. Magnets are characterised by a range of properties, the most important are:
- Magnetic, remanence Br, coercivity HCB and max. energy product (B·H)max.
- Dimensions and tolerances.
- Any holding force.
- Maximum and minimum working temperature and if possible temperature profile.

General features:
The magnets offered by Sintex are isotropic made by pressing neodynium, iron, boron powder mixed with a polymer binder. The characteristics of the magnets from Sintex are high mechanical strength, and thus good magnetic properties.
Thin-walled ring shaped magnets can be made with no chipping of the edges. Height to diameter ratios of more than 2:1 even with a thin wall thickness is possible by our process.
Surface protection:
In specific applications a surface coating or treatment can be necessary to protect the magnet against the environment, e.g. water or excessive humidity. Sintex offers different possibilities regarding surface protection and further information on these may be requested from Sintex. |

Our range of equipment of MAGNETIC SEPARATION for the ferric particle purification (magnetic) that is in the processes of production like smeltings, cementeras, iron and steel industry, etc.; in the industry of recycling, nourishing, ceramic, brick, etc.; or also in the extraction of raw material like mines, quarries, etc.
Another important application is the protection of the machines that take part in the own production and that the ferric particles like shavings, nuts, screws, nails, etc. Can aggravate them.
All these processes require of elements that eliminate all the iron particles, being avoided therefore the delay or rejection in the production, obtaining a quality of the significant product.
All our equipment is made by means of PERMANENT MAGNETS constituting a safe and simple source since its installation does not depend on electricity. In addition, the quality of our product guarantees of by life the benefits of permanent magnets.
Our range of equipment of MAINTENANCE for the transport by means of magnetic systems that start up, they move and they deposit ferromagnetic pieces partial or completely. This displacement can be realized by means of a change of axis or level.
The principle of our systems of magnetic transport bases in the permanent magnet use that creates a magnetic field and generates the mobility of pieezas.

Toshiba pioneered the development of Cobalt (Co)-based amorphous (non-crystalline) magnetic alloys for electronic applications. Toshiba offers amorphous magnetic cores for noise suppression, mag-amps, snubbers and pulse transformers. Key applications for these amorphous cores include switching power supplies, noise sensitive equipment, medical instruments and telecommunications.
Improvements in magnetic properties have resulted from Toshiba's commitment to research and development. Toshiba continues its R&D programs to further improve the properties of the amorphous alloys and the magnetic components made from them.

Electromagnet is a type of magnet in which the magnetic field is produced by the flow of an electric current through the coil. The magnetic field disappears when the current ceases.
As a current is passed through the coil, small magnetic regions within the material, called magnetic domains, align with the applied field, causing the magnetic field strength to increase. As the current is increased, all of the domains eventually become aligned, a condition called saturation.
The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be rapidly manipulated over a wide range by controlling the amount of electric current. However, a continuous supply of electrical energy is required to maintain the field.
In applications where a variable magnetic field is not required, permanent magnets are generally superior. Additionally, permanent magnets can be manufactured to produce stronger fields than electromagnets of similar size.
Electromagnets are used in many situations where a rapidly or easily variable magnetic field is desired. Many of these applications involve deflection of charged particle beams; the cathode ray tube and mass spectrometer fall into this category.
Popular uses: linear motor, electric motor, circuit-breakers, electromagnet brakes, electromagnet clutches, metal lifter, magnetic separators, and more. |
