Permanent magnets in cars

Permanent magnets in various types of materials, such as neodymium (NdFeB), samarium cobalt (SmCo), ferrite, AlNiCo and plastic-coated magnets are used in many different automotive parts (e.g. door locks, sun roofs, ABS, speakers, windscreen wipers, electric window regulators) making magnets indispensable in our cars. Considering that safety is always the highest priority in this branch, quality is put above all else.

Goudsmit is one of the few European magnet suppliers that is both ISO 9001:2008 and ISO/TS 16949:2009 certified and capable of conducting internal process audits in accordance with VDA6.3. This, along with advanced measuring equipment, ensures that every aspect of our magnets complies with the applicable quality and safety requirements. Why does the automotive industry require magnet measurements? You can read it here

Products

Neodymium magnets (NdFeB)

Neodymium-Ferro-Boron (NdFeB) magnets are delivered by Goudsmit under the brand name Neoflux®. It is the most powerful magnet, with a very high energy product.

More information

Samarium-Cobalt magnets (SmCo)

Samarium-Cobalt (SmCo) magnets have excellent magnetic characteristics, a low temperature coëfficiënt and high stability.

More information

AlNiCo magnets

AlNiCo magnets are made of Aluminium, Nickel and Cobalt. Most AlNiCo magnets are cast. This can take place in complex forms.

More information

Ferrite magnets

Ferrite magnets or ceramic magnets are the most used magnets. The applications of ferrite magnets are very broad.

More information

Plastic-bonded neodymium magnets

Plastic bonded neodymium magnets can be manufactured in complex forms by means of pressing or extruding.

More information

Neodymium (NdFeB) pot magnets

Neodymium (NdFeB) pot magnets have a magnetic force that is 7x stronger than that of ferrite pot magnets. They can be used at temperatures of up to around 80 °C.

More information

Samarium-Cobalt (SmCo) pot magnets

Samarium-cobalt (SmCo) pot magnets offer the unique combination of high magnetic force and high operating temperature of up to around 200 °C.

More information

Ultrasonic welding of magnets

Ultrasonic welding is a means to encapsulate magnets or provide a casing. It is a welding technique in which objects are joined using high-frequency ultrasonic acoustic vibrations.

Gluing magnets

Goudsmit regularly uses adhesives for product assembly. We know exactly how much to use and the best curing process, both of which are essential to ensure the product functions correctly.

More information

Overmoulding of magnets

Magnets are overmoulded when they must be completely covered for environmental reasons. This is an excellent technique for securely assembling parts.

More information

Injection moulding of magnets

Injection moulding is usually used to join magnets and plastics without gluing. This is a technically advanced solution that requires precision moulds and magnets. Goudsmit has what it takes.

Assembling magnets mechanically

Press fits and screws are some non-risky methods for assembling magnetic systems. Mechanical assembly is sometimes preferable, because it is easy to test and inspect.

More information

AlNiCo pot magnets

AlNiCo pot magnets are coated by a steel pot, in between which a non-magnetisable raw material has been inserted. Applicable for very high operating temperatures up to around 450 °C.

More information

Ferrite pot magnets

Ferrite pot magnets, also called ceramic pot magnets, are provided with a steel pot that ensures cover. Only a small installation height is necessary, and they can be used up to around 200°C.

More information

Electromagnets

Electro pot magnets are switchable. Electromagnets can be used in situations in which products must be picked up and positioned.

Optical 3D Scanner

With the optical 3D scanner the full geometry of an object can be measured, analysed and recorded with perfect accuracy.

More information

Permagraph

Using the permagraph we determine the exact magnetic properties and compare them to the required specifications.

3D flux meter

Ideally, the border runs exactly between the north and south poles and perpendicular to the north-south axis. With the 3D fluxmeter we measure the actual angular deviation.
