Previously, I also mentioned the function of the large and small end magnets, and the specifications of the large and small end magnets. I won't go into much detail here. If you want to know more, you can check at the end of the article. Today, I will mainly talk about the production process and processing flow.

Take the specifications of a large and small magnet for example, D12 * 3+d10 * 3. First of all, it is necessary to make a cylinder with raw materials of 12 * 34. When it comes to this raw material, it is necessary to specify a material that cannot be added with lanthanum or cerium. Although the cost may vary by 5 yuan per kilogram, adding this component to the material is relatively difficult to reprocess and also affects the appearance of the product. The finished product will be pitted and unsightly, and the next step will be taken when the raw materials are fired, The slicing process can produce 5 pieces of 12 * 6 from a single column, with 1.5 removed material skins and 0.3 blade edges. The length of 34 is just right and not wasted at all. The resulting 12 * 6 is a small cylinder, which is then processed into a finished product specification of 12 * 3+10 * 3,

This process is the most time-consuming. A person can only make up to 3000 magnets per day based on an 8-hour calculation. The main reason why the unit price is higher than ordinary magnets is that they are expensive here. In addition, the packaging area will also be as high as 0.02 pieces, because these types of magnets need to be distinguished by the N/S grade of the big end and small end. Generally, our customers who are working on them are unified with the N grade of the small end. After processing, they are chamfered, plated, packaged, and magnetized, Many people here are curious. Isn't a magnet magnetic? How did it stick together when it got stuck on the magnetizing machine? Haha, this is how to magnetize it under high voltage. After electroplating, we will lay it flat on the desktop, divide the big end and small end, and wrap them all in newspapers to magnetize in a unified direction. For example, when the small end hits the N-level mark, we will twist the small end of the newspaper when packaging, so that the magnetizing will make the twisted end of the newspaper face down and it will be okay. After magnetizing, we will pack and magnetize the paper. These are all manual tasks, The editor is also packing quite quickly now, hee hee!
