The manufacturing process of DC electromagnetic locks mainly revolves around the manufacturing of the core electromagnet components and the overall assembly and debugging.
Core Machining: Soft magnetic materials such as silicon steel sheets or ferrite are used for stamping to ensure high permeability and low remanence, thereby improving attraction efficiency and reducing residual magnetic force after power failure.
Coil Winding: Enameled copper wire is precisely wound according to the designed number of turns and resistance value. Common operating voltages are DC12V or DC24V, with some products supporting a wider voltage range.
Frame/Carrier Forming: The support structure is created through mold injection or metal stamping. Some manufacturers offer custom sizes.
Push Rod/Armature Assembly: Assembling the movable armature assembly requires low friction and high wear resistance. A spring is often used to achieve automatic reset upon power failure.
Complete Assembly and Testing: Integrating components such as the core, coil, housing, and push rod, and conducting tests on attraction force, stroke, lifespan, and withstand voltage.
