rubber magnets

The manufacturing process of rubber magnets is much the same as other products. In the design of the formula, the first to determine the species of magnetic powder, particle size and dosage. Next should be determined according to the requirements of the use of rubber, such as wear-resistant medicine selection of natural rubber. In the process, before or after vulcanization needs to be added to other products do not have the magnetization process, in order to give the product permanent magnetism. The advantage of magnetization before vulcanization is that the direction of the external magnetic field remains unchanged, through the rubber network is more smooth; after vulcanization magnetization through the poorer, but the operation is more convenient. In short, each has its own advantages and disadvantages. Rubber magnets, also known as bonded permanent ferrite magnet , are made of bonded ferrite powder, rubber or plastic and other materials, through extrusion, calendering or injection molding. Due to the high plasticity of the material itself, the finished or semi-finished products can be cut, perforated, longitudinally cut and mounted on other materials at will, and is not easy to demagnetize, has a good corrosion resistance, is mainly divided into two major categories of Isotropic Rubber Magnets and anisotropic rubber magnets. The difference is as follows: 1. Different magnetic properties: Isotropic rubber magnetism is weaker, while anisotropic rubber magnetism has a higher magnetic function. 2. Different working temperature and density, the density and temperature of the Isotropic rubber magnet are lower than that of the anisotropic rubber magnet. 3. Different application areas: the Isotropic rubber magnet is mainly used in refrigerator magnets, car stickers, printing products, and promotional items. And anisotropic rubber magnets, a large number of applications in micro-motors, computers, laser printers, copiers, magnetic toys and other areas of the preparation process of rubber magnets.

There are many different types of magnets, and there can be different types based on different categorization criteria. Below are some common ways of categorization and the corresponding types: 1.Classified according to material properties: Metal alloy magnets: include neodymium-iron-boron magnets (Nd2Fe14B), aluminum-nickel-cobalt magnets (AlNiCo), and samarium-cobalt magnets (SmCo). Each of these metal alloy magnets has its own characteristics, such as NdFeB magnets are one of the highest performing magnets commercially available, while AlNiCo magnets are capable of operating at high temperatures. Ferrite permanent magnet materials: mainly made of raw materials such as BaFe12O19 and SrFe12O19, manufactured through the ceramic process method, have good temperature resistance and low price, moderate performance, has become one of the most widely used permanent magnets. 2.Classified according to shape: Including square magnets, tile magnets, shaped magnets, cylindrical magnets, ring magnets, circular sheet magnets, magnetic bar magnets and so on. These different shapes of magnets can meet the needs of various specific applications. 3.Categorized according to application area or industry: Such as magnetic components, motor magnets, rubber magnets, plastic magnets and so on. This categorization is mainly based on the specific application and role of magnets in each field. 4.Other special types of magnets: Permanent magnets: are magnets made of materials that have their own inherent magnetic properties. Electromagnets: are coils or other forms of electromagnetic devices that produce a magnetic field when energized. Soft magnets: characterized by high permeability and low coercivity, they are often used in applications that require frequent changes in the direction of the magnetic field.
