Bolt Aluminum Electrolytic Capacitor Production Process

  Basic materials of bolted aluminum electrolytic capacitors: anode foil, cathode foil, electrolytic paper, lead wire (guide foil), cover, electrolyte, aluminum case, explosion-proof valve, sealing ring, sleeve, gasket, etc.

  Bolt electrolytic capacitor production process: cutting (anode foil, cathode foil and electrolytic paper are cut according to the specified width), winding (anode foil, cathode foil, electrolytic paper and lead wire (guide foil) are rolled into a core), laser riveting (lead wire and cover plate on the core are welded together to draw out the capacitance), impregnation (electrolyte is dipped inside the core), core loading (core is loaded into the aluminum case), sealing (aluminum electrolytic capacitor is sealed), aging (repairing) capacitors, aging (repairing the oxide film on the surface of aluminum foil and eliminating defective capacitors), sleeving (putting the capacitor on the logo and insulating the capacitor), measuring (checking whether the electrical properties of the capacitor meet the requirements), external inspection (checking the appearance and dimensions of the capacitor), packaging (packing the capacitor)
