Video on Automatic Magnet Magnetization—Jiuju Magnetizer
August 17, 2026
Magnetization itself is a physical process that takes place in milliseconds; what truly slows down the overall production cycle are the manual loading, unloading, and alignment and calibration steps. In manual magnetization mode, workers must pick up and place each part individually and verify the polarity direction, which takes several seconds per part. Production capacity fluctuates significantly depending on the workers’ skill level and fatigue, and the strong magnetic field environment also poses safety hazards.

Why Does the Tip “Stick” to the Screw? A Video Explanation of Magnetization—Jiuju Magnetizing Machine
August 2, 2026
Magnetic screwdrivers are typically made of alloy steel, which inherently possesses some residual magnetism. When magnetized, the screwdriver is placed in a strong pulsed magnetic field, causing the internal magnetic domains to align axially. Once the external magnetic field is removed, the screwdriver retains a stable magnetic field, enabling it to attract iron screws.

”In traditional pre-magnetization processes, magnetizing the magnets in advance causes the magnetic poles to repel each other and attract iron filings during motor assembly, which limits yield rates and poses safety hazards.” The "assemble first, magnetize later" approach uses integrated magnetization technology to allow magnets to be precisely positioned in a non-magnetized state, with magnetization and shaping performed uniformly after assembly is complete. This innovation eliminates magnetic interference, enables the design of motors with higher rotational speeds, and boosts assembly efficiency by more than 30%. It is rapidly becoming the mainstream choice among manufacturers of new energy motors and servo motors.

Video Guide on How to Select a Magnetizing Machine—Jiuju Magnetizing Machines
August 8, 2026
When selecting a magnetizing machine, most people focus solely on the main unit’s power as their first step—and this is precisely the biggest misconception. The magnetizing effect depends on the synergy between energy output and the magnetic field focusing provided by the fixture, not simply on the rated power.

Before proceeding, be sure to disconnect the equipment from the main power supply and verify that the unit is completely de-energized to prevent any live wiring work. First, inspect the power cord and connection cables to ensure there is no visible damage or wear, and that the connectors are free of debris and dirt. Match the connectors to the corresponding labels on the equipment, and connect the power supply line, magnetizing coil line, and control line in sequence. Ensure the plugs are securely locked into place, and arrange the cables neatly so they are not pinched or tangled.
