About Plastic Magnet

Plastic magnets are magnets produced by combining magnetic powders (e.g., Ferrite, NdFeB) with resins. With this technology, plastic magnets are more flexible, lighter, and more corrosion-resistant than traditional metal magnets. Plastic magnets are commonly used in sensors and motors across a wide range of applications, such as automotive, home appliances, precision electronics, and medical devices.

Key Features of Plastic Magnets

Feature 1: Capable of Complex Shapes

Through manufacturing processes such as injection molding and compression molding, plastic magnets enable integral molding of complex shapes that are difficult to realize with conventional metal magnets. This technology greatly increases design flexibility, making it suitable for precision devices and applications that require specialized shapes. For example, it is well suited for manufacturing detailed components used in automotive sensors and motors, as well as home appliances.

Feature 2: Flexible Material Selection for Each Application

Plastic magnets offer customization flexibility through the selection of magnetic powders and resin types to match required performance. Choosing magnetic powders like Ferrite or NdFeB allows adjustment of magnetic strength, heat resistance, and chemical resistance. As a result, magnets with optimal properties can be provided for a wide range of industries, including automotive, electronics, and home appliances.

Feature 3: Excellent Durability

Plastic magnets are lightweight and highly resistant to corrosion compared to metal magnets. In addition, plastic magnets deliver stable performance under changes in temperature and humidity, providing long-term reliability even in demanding conditions. This makes them well suited for durability-critical applications, including automotive, industrial machinery, and outdoor equipment.

Plastic Magnet Production Methods

Plastic magnet production starts with combining magnetic powders with resins to form a uniform compound. Next, the mixed material is loaded into an injection molding machine and heated until it melts. The melted material is injected into a mold and then cooled to solidify. Finally, the molded parts are removed, and, if necessary, additional processing and quality inspections are performed.
