Battery packs, connectors and cable entries.
New energy / interface
New-energy seals for battery packs, cable entries and connector interfaces.
PRESIS develops EV sealing parts that help control heat, vibration, compression set and interface stability in new-energy projects.
Buyer pain points
New-energy sealing failures often come from heat, vibration and fit drift.
- Battery packs need sealing stability over temperature changes.
- Vibration and compression set can change long-term performance.
- Connector and cable-entry parts often need precise interface geometry.
- Customers want engineering support before tooling release.
PRESIS solution
EV sealing route
We use the application data to review the sealing geometry, material choice and manufacturing route before tooling starts.
That helps the buyer reduce risk in the first iteration and improve the chance of successful mass production.
Material and process
EV sealing projects need heat, vibration and compression-set control.
| Project need | Recommended route | Buyer questions to prepare |
|---|---|---|
| Battery pack seals | EPDM, FKM or silicone depending on temperature and medium. | Pack structure, temperature range, sealing path and life target. |
| Cable-entry seals | Custom geometry with stable compression and assembly fit. | Wire diameter, connector size, groove detail and harness routing. |
| Connector interfaces | Precision sealing compound matched to hardware and tolerance. | Drawing, sample, vibration condition and annual demand. |
