1. The slitting process involves cutting the semi-finished film into finished films. Equipment required for semi-finished metalized film cutting machine

2. The winding process rolls the finished film into a core. The core is a fundamental and important component of membrane capacitors. The finished film requires equipment such as a winding machine for the core rod

3. The gold spraying process involves spraying a metal layer on both ends of the core for easy welding of lead wires. Zinc wire and zinc aluminum alloy wire require equipment such as a gold spraying machine

4. After the core of the empowerment process is sprayed with gold, charge and discharge testing is carried out on the core. Check if its capacity, loss, self-healing, and withstand voltage meet the design requirements/require equipment empowerment machine

5. The welding assembly process involves soldering the core onto the leads and combining them in series or parallel for soldering, wires, and copper foil. Equipment such as automatic soldering machines and soldering irons are required

6. The core and core assembly testing process conducts pressure resistance, capacity, and loss tests on the core and core assembly. Required equipment includes capacity tester, voltage tester, and insulation resistance tester

7. The impregnation process involves impregnating the core and core assembly under high temperature and vacuum conditions to remove air and moisture from the core. Insulation oil requires the use of an equipment impregnation machine

8. The assembly process involves installing the core assembly into the casing, insulation, and installing insulation films such as lead wires, insulation paper, casing, insulators, and lead pillars.

9. The semi-finished product testing process conducts voltage resistance, capacity, loss, and insulation tests on the semi-finished product. Required equipment includes capacity tester, voltage tester, and insulation resistance tester

10. The packaging and painting process involves packaging, polishing, cleaning, and painting of semi-finished products. Equipment required: argon arc welding machine

11. The finished product testing process involves conducting voltage resistance, capacity, loss, and insulation tests on semi-finished products. Depending on the situation, usage time tests, as well as accurate capacity, loss, and internal resistance and inductance tests, require equipment such as capacity testers, voltage testers, insulation resistance testers, precision high-voltage bridges, AC/DC voltage withstand testing devices, oscilloscopes, compass coils, and high-voltage capacitance testing devices.
