Battery Manufacturing EquipmentHangke fill-port pin insertion and removal family
Hangke makes two matching machines for cell fill ports. One inserts a pin into the electrolyte filling port automatically. The other removes it so the cell can go on to extraction, second filling and sealing, using force and position control, vision and data tracing. Hangke gives a ≥99% equipment good-product figure for both.
What the insertion and removal machines do
Hangke describes the insertion machine as placing the pin in the electrolyte filling port automatically. The removal machine prepares cells for extraction, second injection and sealing, and lists force and position control, vision and data tracing. Those controls are listed for removal only, so ask whether your insertion machine has them.
Send the port and pin drawing, tolerances, material and the allowed condition of the port before and after each step. State whether insertion is a temporary closure or a step before a later weld or seal, since the page does not name the final sealing method. For removal, define how the pulled pin and the open cell are handled and which station receives them next.
| Parameter | Published value | Record status |
|---|---|---|
| Each page stated unqualified good-product figure | ≥99 % | known |
Catalogue values apply to the configuration and test method the maker states. Ask for the values that apply to your configuration.
Fit, force and position limits
Agree insertion depth and position, the allowed force or travel where it matters, and how a missing, crooked or half-seated pin is detected. For removal, ask for the sensor range, resolution and saved trace of the force and position control. The summary gives no figures for any of these, and names vision without listing what it detects or how accurately.
Run cells at the edges of your tolerance band using the supplier's safe test set, and inspect the port, pin and cell for damage or residue. Include a failed extraction and a missing pin, and agree the hold and reject route. Ask Hangke how the ≥99% figure is defined and sampled, and base acceptance on the agreed mechanical and process limits.
Passing the open cell to the next station
Define the ID and status hand-off to extraction or second filling, and the environment and holding time allowed for an open port. Specify whether pins are reused, scrapped or kept for analysis, and ask Hangke how the machine handles each case. Records should show the pin step apart from the later sealing step.
Ask for tool changeover, wear checks, cleaning and access and lock-out procedures. After a stop mid-motion, recovery must establish whether the cell holds a pin, a half-pulled pin or an open port before it moves on. Count good operations on your specified fit, and check final sealing and cell performance at their own stations.
Pins are inserted for negative-pressure formation, which the page on formation and grading describes, and pulled out again ahead of final closure at the Hangke sealing-pin welding station.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| What state follows insertion? | The catalogue describes automatic insertion and names no final sealing method. | Define depth and fit and the next closing step. |
| Which controls belong to removal? | Force and position control and vision are listed for the removal machine. | Request sensor and detection specifications for your configuration. |
| How is an open cell transferred after removal? | The catalogue gives no holding conditions for the open cell. | Specify ID hand-off, environment and status after an interruption. |
