Production Processes

  • Winding
    Winding
    This is the process where conductive material, usually metal foil, is wound tightly to form the core of the capacitor. This winding is crucial for creating the capacitor's ability to store and release electrical energy.
  • Hot Pressing (Flat Core)
    Hot Pressing (Flat Core)
    Here, the wound core undergoes hot pressing to flatten it. This step is important for shaping the capacitor and can also influence its electrical characteristics.
  • Gold Spraying
    Gold Spraying
    Sputtering gold onto the capacitor components is likely a method of applying a very thin layer of gold. This layer can be important for improving conductivity and protecting against corrosion.
  • Heat Treatment
    Heat Treatment

    The components are subjected to heat treatment. This process can relieve stresses in the materials, improving durability, and ensuring the stability of the capacitor's electrical properties.

  • Core Testing (Energizing)
    Core Testing (Energizing)

    Testing the core, especially after energizing, is crucial. This step ensures the core to meet the necessary electrical specifications and is free from defects.

  • Welding
    Welding
    Welding is used to securely connect various components of the capacitor. This step must be performed with precision to ensure structural integrity and reliable electrical connections.
  • Potting
    Potting
    Potting involves encasing the capacitor in a protective material. This material protects the internal components from environmental factors and mechanical stress.
  • Final Product Testing
    Final Product Testing
    After assembly, the finished capacitor is rigorously tested. These tests confirm that the product meets all required specifications and performance standards.
  • Inspection
    Inspection
    A thorough inspection is conducted to ensure the quality of the finished product. This step is critical for maintaining high-quality standards.
  • Storage
    Storage

    Finally, the capacitors that pass all tests and inspections will be stored, which are ready for distribution or further processing.
