Battery Manufacturing EquipmentGelon laboratory post-formation pouch degassing vacuum sealer
Gelon's laboratory degassing sealer works on pouch cells after formation. It punctures the gas pocket, collects the excess electrolyte and makes the final vacuum seal. Heating reaches 250°C, sealing time adjusts from 0 to 99 seconds and the seal edge is 5 mm wide. It suits labs and pilot lines finishing small batches of formed pouch cells.
Puncture, collect, seal
The machine pierces the air or gas bag, recycles the excess electrolyte and then vacuum seals the pouch. Gelon lists heating up to 250°C, sealing time from 0 to 99 seconds and a 5 mm seal edge. Compressed air is 0.5–0.8 MPa, and the supply comes as AC220 V/50 Hz or 110 V/60 Hz; name the version you need.
Cell size range, gas pocket geometry, vacuum range, heating uniformity and pressing force are not listed. The 0.5–0.8 MPa figure is the air supply, so ask separately for the vacuum level and the force at the seal. Request the chamber, fixture and seal head drawing. Edge trimming and OCV testing are done on larger finishing lines.

Where the gas and electrolyte go
Describe the state of the formed cell, the electrolyte and where the gas pocket should be opened. Ask for the puncture method, collection path, wetted materials and cleaning access. Gelon says excess electrolyte is recycled; ask how much is collected and treat any reuse as your own decision after testing.
Define how the cell is held and how much movement the body and tabs can take. Ask how the machine tells a correctly placed pouch from one that should not be punctured, since no sensing or interlock is listed. Run the demonstration with your gas pocket drawing, your cells and your planned collection procedure.

Build a seal recipe for your laminate
Agree how temperature is measured, the dwell, the force and the vacuum reference for your laminate. Set the seal position, the final pouch shape and the inspection that proves integrity. Seal strength and leak tightness have to be tested on your film. If residual gas or leak rate is part of acceptance, write down the test method.
Seal a run of cells, interrupt one cycle, then clean and change over. Find out which loading, puncture and unloading steps are manual and how an unfinished cell is set aside. Expect to measure cycle time yourself, as none is listed. At handover you should have a proven recipe and a record of seals that passed.
Gelon's profile lists the filling and sealing machines used before formation, and the formation and capacity grading page explains where the gas comes from.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Does the gas pocket fit the actual fixture? | The page lists puncture without geometry or positioning limits. | Approve pouch, chamber and head drawings. |
| What does electrolyte recovery mean? | The page says excess electrolyte is recycled, with no method or quantity. | Define collection, compatibility and cleaning, and test before any reuse. |
| How is the final seal accepted? | The page lists temperature and time limits only. | Qualify a laminate-specific seal and any required leak test. |
