    Behind the Scenes on How Magnets are Made – A Goudsmit UK Insight

    How Magnets are Made

    In the realm of manufacturing and industrial engineering, the creation of magnets stands out as a marvel of modern science and technology. Magnets are integral to our daily lives, powering everything from household appliances to sophisticated medical devices and also renewable energy solutions. At Goudsmit UK, we pride ourselves on not just being a part of this vital industry but also on our commitment to innovation and quality. This blog post takes you behind the scenes to unveil the fascinating journey of magnet production, from the extraction of raw materials to the final assembly. Moreover, we’ll explore how our Magnetic Force Calculator can optimise your projects by ensuring you select the most suitable magnet for your needs.

    The Magnet Manufacturing Process: A Step-by-Step Guide

    1. Raw Material Sourcing

    The journey begins with the sourcing of raw materials. The primary ingredient in most magnets is iron, combined with various alloys such as neodymium, boron, and samarium. This is depending on the type of magnet being produced. These materials are mined from the earth, therefore, requiring a detailed understanding of geology and sustainable mining practices to ensure environmental impact is minimised.

    2. Alloying and Melting

    Once sourced, the raw materials are alloyed and melted in a high-temperature furnace. This process requires precise control over temperature and timing to achieve the desired magnetic properties. The molten alloy is then cooled and solidified into bars.

    3. Milling and Orienting

    The bars are then broken down into smaller particles through a milling process. This step is crucial for creating the right particle size and texture for the magnets. Following milling, the particles are oriented in a magnetic field. This step aligns the particles’ magnetic domains and significantly enhances the magnet’s strength.

    4. Pressing and Sintering

    Next, the oriented particles are pressed into a die to form the magnet’s shape. This can be done under various conditions, including room temperature (cold pressing) or elevated temperature (hot pressing). The pressed magnets are then sintered in a furnace, which bonds the particles together at a molecular level, further increasing their magnetic strength.

    5. Machining and Coating

    After sintering, the magnets are machined into their final shapes and sizes. Precision machining ensures that the magnets meet the strict tolerances required for specific applications. Moreover, to protect the magnets from corrosion and enhance their physical properties, a coating is applied. Common coatings include nickel, zinc, and epoxy.

    6. Magnetisation and Testing

    The final step in the manufacturing process is to magnetise the magnets. This is done using a powerful magnetic field that aligns the domains in the direction of the desired magnetic pole. After magnetisation, rigorous testing is conducted to ensure each magnet meets Goudsmit UK’s high standards for magnetic strength, durability, and also performance.
