Flexible response to different projects, highly customizable magnet solution
Brief introduction of PMMA-permanent magnet materials applications
PMMA magnet is a permanent magnet made of polymethyl methacrylate, which has the advantages of high magnetism and low cost. Compared with other permanent magnet materials, its initial magnetism is slightly worse, but its performance is good at high temperature. PMMA magnets can be produced in different sizes and shapes, including bars, circles and squares. In addition, in the manufacturing process, the requirements of high customization can be achieved by customizing the formula and magnetic field conditions.
The specifications, magnetism, size, quality, durability, high temperature resistance and performance grades of PMMA magnets are as follows:
1. Specifications
The specifications of PMMA magnets are usually designed and produced according to the standards of permanent magnets. For example, the specifications of conventional Sanen magnetic industry include N35, N38, N40, N42, N45, N48, N50 and other series.
2. Magnetic force
The magnetic force of PMMA magnet can be adjusted by changing the formula and heat treatment conditions. In general, its magnetic force is between 0.8 and 2.0 Tesla.
Step 3: Size
The size of PMMA magnet can be customized according to the needs of customers. Conventional dimensions include diameter, height, length, etc.
4. Quality
The cost of PMMA magnet is relatively low, but the requirements for supporting different application scenarios are different and the quality is also different. In general, the quality of PMMA magnets ensures the stability and reliability of customers’ application scenarios.
5. Durability
PMMA magnet has excellent durability and can run for a long time. Usually, its durability is determined by its formula and treatment conditions.
6. High temperature resistance
PMMA magnet can work in high temperature environment and keep stable magnetism in the range of 100 C-150 C.. This makes it widely used in applications such as motors and generators.
7. Performance brand
The name of PMMA magnet performance brand is similar to that of permanent magnet, and usually "n" plus a number or letter indicates the level of magnetic force. For example, N38, N42 and so on.

Key factors of choice
1. Application of PMMA magnet in motor field.
PMMA magnets are widely used in the field of motor manufacturing, mainly in the following aspects:
A. Small motor
The manufacturing cost of PMMA magnet is low, which can meet the application of small motor. For example, small motors such as automobile power windows and central locks need to be miniaturized and lightweight, and PMMA magnets are meeting these requirements.
B. Ultra-high speed motor
The high temperature resistance of PMMA magnet makes it possible to be used in the field of ultra-high speed motors. For example, the super-high-speed motors such as bearings and permanent magnet synchronous motors that can be used in automobile and aerospace applications need high-temperature resistance and corrosion resistance, and PMMA magnets meet these requirements.
2. Application of PMMA magnet in medical field.
PMMA magnets are widely used in the field of medical devices, mainly in the following aspects:
A. Diagnosis and treatment
PMMA magnet can be used as the main element of magnetic resonance imaging (MRI) and magnetic guided therapy (MFGT) in medical field. In MRI, it is usually used as a basic magnet with high flux density and good magnetic field uniformity; In MFGT, it is usually used as a needle guide or a position detector of a cutter. These instruments need to have high magnetic properties, low cost and high temperature resistance, and PMMA magnets meet these requirements.
B. Rehabilitation treatment
PMMA magnet can be inserted into the surface tissue of human body and directly contact with nerve tissue, and then effectively stimulate regular nerve activity, thus promoting the performance recovery. These therapeutic devices usually need magnets with specific sizes and shapes, which can be satisfied in the manufacture of PMMA magnets.
3. Application of PMMA magnet in the field of consumer goods
PMMA magnets are also widely used in the field of consumer goods, mainly in the following aspects:
A. Color TV
PMMA magnets can be used to make small and easy-to-install speaker units and provide high-quality sound output for color TV. These devices need to have specific size, shape and performance requirements, which can be met in the manufacture of PMMA magnets.
B. video games
PMMA magnets can also be used in electronic games, such as handheld game machines, game consoles and other devices, as a key element of sensors. These devices need to have good performance and reliability, especially after repeated use, and PMMA magnets meet these requirements.
These applications show that PMMA magnets are widely used and highly customizable. Its performance and characteristics make it one of the first choice materials in applications such as motors, medical devices and consumer goods.
