Problems solved by technology
[0004] The general processing method of composite magnets in the processing process is to mix various raw materials and then form them by compression molding. However, during the compression molding process, the composite magnets in the mold tend to adhere to the mold when they are solidified, so that when the finished composite magnets are taken out for collection more intensive work

Abstract
The invention relates to a production process of a soft magnetic coupling permanent magnet bonded composite magnet, which relates to the technical field of magnets and comprises the steps of raw material purchasing, mixing, material drying, injection molding, post-processing, final inspection and packaging and warehousing. The magnetic powder, the binder, the lubricant, the coupling agent and the modified plastic which are required for producing the composite magnet are purchased firstly, then the materials are sequentially added into the extruder to be mixed and extruded to obtain the composite magnet, and the extruded composite magnet is put into the drying oven to be dried and then is subjected to injection molding through an injection molding machine. The method comprises the following steps: carrying out injection molding on a composite magnet, removing burrs and overflowed edges of the composite magnet subjected to injection molding, carrying out flaw detection on a finished product of the processed composite magnet by using an online eddy current flaw detector, packaging the qualified finished product of the composite magnet, and storing the qualified finished product of the composite magnet in a warehouse, so that the manufacturing and collecting work of the composite magnet is completed. And the finished product of the composite magnet bonded on the mold does not need to be manually demolded, so that the working intensity is reduced.
Description
technical field [0001] The present application relates to the technical field of magnets, in particular to a production process of a soft magnetic coupled permanent magnet bonded composite magnet. Background technique [0002] Magnetic materials are generally divided into soft magnetic materials and hard magnetic materials. Among them the soft magnetic material is one with low and high. Easy to magnetize and easy to use, widely used in and electronic equipment. Hard magnetic materials, also known as permanent magnetic materials, are materials that remain constant once they are magnetized. [0003] In the related art, composite magnets can be obtained by compounding soft magnetic materials and hard magnetic materials with ordinary polymer materials. This composite magnet not only maintains various magnetic properties of the original magnetic materials, but also has the processing and molding technology of polymer materials. It is simple and has the advantages of good elast...
