A ferrite magnets factory produces ring magnets for loudspeaker drivers. These ferrite magnets factory rings have an outer diameter of 30 to 200 mm. The center hole of a ferrite magnets factory ring accepts the voice coil.

A ferrite magnets factory uses a die‑compaction press for ring formation. The inside diameter of ferrite magnets factory rings is ground to 0.05 mm tolerance. A ferrite magnets factory can magnetize rings with two or four poles.

The Y30 grade from a ferrite magnets factory is common for car speakers. A ferrite magnets factory making Y40 grade offers higher energy for subwoofers. The plating on ferrite magnets factory speaker magnets is often zinc or nickel.

A ferrite magnets factory supplies magnetized rings in pallet quantities of 5,000. The orientation of ferrite magnets factory rings is radial or axial depending on design. A ferrite magnets factory with a multi‑pole magnetizer saves assembly time.

The glue used for ferrite magnets factory rings must withstand speaker vibration. A ferrite magnets factory tests each batch for flux uniformity. The remanence of ferrite magnets factory Y35 grade is 400 mT minimum.

A ferrite magnets factory with an in‑house lab checks coercivity with a hysteresis graph. The price of ferrite magnets factory products is 1/10 that of neodymium. A ferrite magnets factory can deliver custom sizes in 4 weeks. For large orders, a ferrite magnets factory offers volume discounts.
