We make various kinds of magnet as per customer's drawing and samples. Our magnet is widely applied the different industrials.
Quality comes from being controlled rather than be done. On the basis of the escalating production equipment and optimized process. Nide spare no efforts and keeps improving for quality control. Quality assurance covered with system, technology and human resources are in full swing.
Magnets for motorcycle starter
Magnets for motorcycle starter are applicable for 70cc, 100cc, 125cc, 250cc starters based on Y30H-2 materials.
