Precision Stamped Safety Components for New Energy Vehicle Battery Systems
As global automakers race to electrify their fleets, the safety of the battery pack has become one of the most heavily scrutinized aspects of vehicle design. A single sub-standard stamped component — a vent, a burst disc, or a cell enclosure — can compromise the integrity of an entire pack. That is precisely why leading new energy vehicle (NEV) and battery manufacturers around the world turn to HEJU Stamping, a China new energy vehicle stamping parts supplier with over 15 years of experience serving the automotive and electronics industries.
Engineered for the Toughest Safety Standards in the Industry
HEJU’s new energy safety device stamping line is purpose-built for the extreme precision and consistency that battery safety components demand. Every part that leaves the production floor is backed by a rigorous, data-driven quality process. We can custom-make electric vehicle prismatic battery safety vents in different designs, sizes, shapes, and set pressures.
- Stable Bursting Value
The tolerance of the single bursting value is within 0.03MPa, and the CPK value is above 4.0
- Most Advanced Imported Film Thickness Tester
Can magnify 1000 times to monitor blasting marks accurately
- High Scoring Accuracy
The residual thickness of the score is less than 0.005mm
- Full part traceability and diverse model support
This level of control is what allows global OEMs to specify HEJU as a qualified supplier for safety-critical components without compromising on lead time or cost.
