Ningbo Maxim Magnetic Industry Co., Ltd.

Rubber magnet is a new type of magnetic material composed of rubber and magnetic materials, which has both the elasticity and flexibility of rubber and the magnetism of magnets, and is widely used in electronics, automobiles, office supplies and other fields. The production process usually includes steps such as mixing, molding, and magnetization, and different process parameters can have a significant impact on product performance. In recent years, with the continuous advancement of technology, the performance of rubber magnets has been continuously improved, and the application range has continued to expand.

Application design

1. Advertising display: make magnetic stickers, magnetic poster frames, etc. With its ability to adsorb on metal surfaces, it is convenient to post and replace advertising content, and is widely used in shopping malls, subway stations and other places. When designing, consider the fit with the advertising screen to ensure the beauty, and the advertising pattern can be printed or pasted on the surface.

2. Electronic devices: for small speakers, headphones, etc. In the design, the size and shape of the magnet are accurately calculated so that it generates the appropriate magnetic field to improve the efficiency of audio conversion. It can also be used for magnetic storage of electronic devices, such as the magnetic flip cover of a laptop and the magnetic holder of a mobile phone.

3. Toy field: designed as magnetic building blocks, puzzles and other educational toys. The softness and magnetism of rubber magnets are used to increase the fun and safety of toys. For example, magnetic bricks can be freely joined, making it easy for children to handle while preventing injuries from collisions.

Production process

1. Ingredients: Mix ferrite magnetic powder, synthetic rubber, additives, etc. evenly according to a certain proportion. The magnetic particle content affects the strength of the magnetic property, and the type of rubber affects the physical properties, so the proportion needs to be accurately controlled.

2. Mixing: Through the internal mixer, open mixer and other equipment, the ingredients are fully mixed, so that the components are evenly dispersed and the comprehensive performance of the material is improved.

3. Molding: Compression molding, extrusion molding and other methods are adopted. Compression molding is suitable for making products with complex shapes and high dimensional accuracy; Extrusion is suitable for making products with continuous shapes, such as sealing strips.

4. Vulcanization: Vulcanization is carried out at a certain temperature and pressure to cross-link the rubber molecules and improve the strength, hardness and stability of the rubber magnet.

quality control

1. Raw material inspection: Strict inspection of ferrite magnetic powder, rubber and other raw materials to ensure that the magnetic properties, purity, physical properties and other indicators meet the requirements.

2. Process inspection: In the production process, real-time detection and adjustment of mixing uniformity, molding dimensional accuracy, vulcanization degree, etc.

3. Finished product inspection: According to relevant standards, the magnetic properties, physical properties, appearance, etc. of the finished product are comprehensively tested to ensure product quality.
