 Injection-molded magnets exhibit high magnetic energy product and coercivity, enabling strong magnetic force output.

 2. Good Temperature Stability

 These magnets maintain stable magnetic properties even under high-temperature conditions, making them suitable for demanding thermal environments.

 3. Excellent Processability

Their compatibility with injection molding allows for the production of complex shapes, offering broad applicability across various fields.

4. Strong Corrosion Resistance

The material demonstrates good resistance to corrosion, ensuring long-term reliability in humid or chemically aggressive settings.

Manufacturing Process Overview

The production of injection-molded magnets involves the following key stages:

1. Raw Material Preparation

Magnetic powder and thermoplastic resin are selected and uniformly blended in specific proportions.

2. Injection Molding

The mixed material is injected into molds using specialized injection molding equipment, with process parameters optimized according to product design requirements.

3. Curing

The molded components undergo a curing period to develop required strength and hardness.

4. Magnetization

A magnetic field or electrical current is applied to align magnetic domains and enhance magnetic properties.

5. Surface Treatment

Additional finishes such as coating or plating may be applied to improve appearance and wear resistance.

Through this manufacturing approach, injection-molded magnets can be mass-produced with advantages in cost efficiency, high productivity, and consistent quality. They provide reliable magnetic solutions for applications in electronics, automotive components, medical devices, and other industries.
