Video on Automatic Magnet Magnetization—Jiuju Magnetizer
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
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.

Video Case Study: Magnetizing Machine for Automotive Motor Rotors—Jiuju Magnetizing Machine
”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.

This issue provides a comprehensive guide to the standard operating procedures for ice water machines. Mastering the correct usage will effectively improve the equipment’s operational efficiency. Before starting the machine, inspect the piping, wiring, and water level to ensure there are no leaks and that all components are in good condition. Turn on the main power supply, check the equipment’s self-test status, and set operating parameters such as water temperature and pressure according to production requirements.
Video on the Wiring Procedure for a 3000V General-Purpose Industrial Magnetizer—Jiuju Magnetizer
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.
