Why Can’t I Get My New Tooling Aligned Right? Three Pitfalls to Avoid When Quickly Changing Setups with Magnetizing Fixtures

Automated Magnetic Charging Integrated Solution
Q1: Every time I change the product specifications, the magnetization becomes unstable, and it takes half an hour of adjustment to get it back to normal. What’s causing this problem?
A: In 90% of cases, the problem lies with the positioning of the production fixtures. The positions of the coils and fixtures vary depending on the product, and many factories rely on visual alignment or marking lines with a marker pen during changeovers—this level of precision is simply insufficient. If the air gap between the coil and the magnet is off by just five threads, the discharge energy coupling efficiency can drop by more than 10 percent. Standardize changeovers by doing three things: Make a positioning plate for each set of jigs that uses pins and定位 holes to achieve quick alignment, eliminating the need for manual adjustment. After a changeover, run the test piece through the process three times; proceed to mass production only after consistency is verified. Label each set of tooling with changeover parameters, specifying which product it is configured for, the voltage to use, and the alignment height—new employees can simply follow these instructions.
Q2: After changing the model, the initial magnetization never reaches full capacity, and I have to repeatedly adjust the voltage to find the right value?
A: It’s not a equipment issue; a step is missing in the changeover process. The contact resistance of new fixtures or re-installed fixtures is different from before, so the discharge energy is actually much lower at the same voltage. After a changeover, discharge the system once without installing the magnet. Use an oscilloscope current probe to capture the waveform and check whether the peak current matches the standard value. If it doesn’t, inspect the fixture’s contact surfaces for oxidation or poor contact. These two issues account for the vast majority of cases where the system fails to fully charge during a changeover. Include this step in the changeover operating procedures. Spending an extra two minutes on this check during each changeover is far more cost-effective than spending half an hour later repeatedly adjusting the voltage.
Q3: How do I choose between copper and aluminum fixtures? What are the consequences of choosing the wrong one?
A: Each has its own uses. Copper has good electrical conductivity and is highly efficient at transmitting discharge energy, but it is heavy, making large fixtures difficult for operators to lift; furthermore, copper can be attracted by strong magnets, which is unsafe. Aluminum is lightweight but has poorer electrical conductivity than copper, resulting in slightly higher contact resistance. The standard practice is to use a copper alloy or copper-tungsten alloy for the conductive contact point—limited to an area about the size of a thumb to ensure contact quality—while the main body of the fixture is made of aluminum alloy to reduce weight, thereby balancing efficiency and operational safety. Note that the surface of aluminum fixtures is prone to oxidation, forming a non-conductive oxide layer. Before each shift, gently brush the contact surfaces with a wire brush. If this simple step is skipped, contact resistance can double after a changeover.

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.

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.
