ZYJ-02 Vacuum Filling Machine

High-Precision Vacuum Electrolyte Filling for Cylindrical Cells

The ZYJ-02 Vacuum Filling Machine is designed for controlled electrolyte injection into cylindrical battery cells under reduced-pressure conditions. In this process, cells are loaded into a tray, sealed inside the chamber, evacuated, and then filled with a metered quantity of electrolyte. Vacuum-assisted filling helps improve electrolyte penetration into porous internal components, supports more uniform wetting, and reduces the risk of trapped gas during early-stage cell assembly.

Key Features and Technical Highlights

This battery electrolyte filling machine is suited to a wide range of cylindrical formats, including common research and pilot-line cell sizes such as 18650, 26650, 32650, CR123 and AA, with changeable clamps or customised tooling depending on the cell geometry. Manufacturer listings describe PLC-based control with a touch-screen human-machine interface, adjustable filling speed and filling cycles, and user-set parameters for vacuum time, air input time and fill quantity. Typical listed specifications include 110–220 V AC, 50/60 Hz operation, 1500 W power, vacuum filling accuracy of ±0.02 g, adjustable filling cycles from 1 to 10 times, a filling range of 0–7 g, vacuum degree to -0.1 MPa, and compressed air input of 0.3–0.6 MPa. The supplied specification image also indicates dimensions of 1100 × 550 × 900 mm and an approximate machine weight of 130 kg.
