Prismatic and cylindrical stations in separate ranges
Dongguan Shuangren describes itself as working on development, manufacturing and service for lithium-battery automation. Its power and energy-storage cell range lists restraint handling, helium charging, plug insertion and removal, wiping, wrapping, airtightness detection and ball sealing. A separate cylindrical range lists sealing machines for several formats.
Each item is a single station, so a full finishing line needs a scope that names every station and interface. The site gives the company name as 东莞市双仁机械设备科技有限公司 and its location as Liaobu, Dongguan. Ask Shuangren for its business licence and a factory visit if you need to confirm the company details.
Leak testing in the cell-finishing sequence
Once electrolyte filling is done, a prismatic cell is closed with a sealing pin or ball and then has to pass a tightness test. Shuangren's catalogue covers the stations around that step, from restraint handling, helium charging and plug insertion and removal to wiping, wrapping, airtightness detection and ball sealing, as well as cylindrical sealing machines.
Leak-test methods differ widely in sensitivity. Pressure decay is simple but coarse. In helium testing the cell holds a little helium and a mass spectrometer looks for it escaping, which picks up far smaller leaks. Ask which method the machine uses, the smallest leak rate it can detect, how it is calibrated against a reference leak and how a failed cell is tracked. The Hangke helium leak-check station shows the helium method in detail.

What these details mean for selection
The featured machine is the Cell airtightness detection machine. The listing names the category without a test method, range or cycle, so its page sets out what to specify before you agree acceptance limits.
Agree the sealing state and who owns each result
Shuangren lists its airtightness machine next to its other finishing stations. Ask for a proposed sequence that states the cell's closure state, any gas preparation, the fixture and the test method, and only then discuss the acceptance limit. Shuangren also sells helium charging stations, so ask whether the airtightness machine itself uses helium or another method.
Decide which party is responsible for the seal and which for the test result, especially if different suppliers provide the stations. Ask for a written method description, reference-leak checks and a traced demonstration on your own cell design.

- The leak-test method used by the airtightness machine (helium or pressure decay).
- Test pressure, leak-rate units and the smallest leak the machine detects on your cell.
- How the fixture separates a cell leak from a fixture leak, and the reference-leak check.
- Cycle time per cell and how a failed cell is tracked.
