1.Equipment Overview

This machine is used for pre-sealing cylindrical 18650 batteries that have been filled with electrolyte and capped.

2.Operation Procedure

1. Pull out the handle of the lower mold mechanism and place the steel shell inside

2. Push the lower mold mechanism to the bottom

3. Press the pneumatic switch with both hands and then release it

4. Pull out the lower mold mechanism after sealing is complete

5. Manually unload

3.Equipment Technical Parameters

1. Incoming Material Standards

• The steel shell must be free of burrs, scratches, and dents.

• The gasket must be clean and free of defects.

• The electrolyte must be clean and free of impurities.

• The incoming material must meet the following standards:

2. Incoming Material Requirements (for caps and grooved steel shells)

• The caps must be free of burrs and scratches.

• The grooved steel shells must be free of burrs and scratches.

• The groove depth must be within the specified range.

3. Inspection Standards (18650 as an example)

• All sealing process parameters of the equipment must be adjustable. After sealing, the battery must be measured at three points (120°).

• The height from the bottom of the steel shell to the bottom of the groove can be adjusted within the range of 60.0~62.0mm (sealing adaptability).

4. Quality Requirements

• The product must be free of burrs, peeling plating, imprints, wrinkles, and leakage after sealing.

• After sealing, the product must be airtight: no leakage under a pressure of 1.0MPa for 120 seconds; no leakage under a pressure of 1.8Mpa for 120 seconds (no leakage before CID pressure relief).

• The bottom sealing and shaping must be free of eccentricity, excessive diameter, and bottom deformation.
