Service Cases

We partnered with a large domestic new energy vehicle company to provide a sealing solution for the battery packs of their latest electric vehicles. The car uses an 800V high-pressure platform, which puts high demands on the battery seal: it needs to be completely waterproof and dust-proof, can adapt to extreme temperatures from minus 40 degrees to 150 degrees, and also guarantees a service life of at least 10 years or 200,000 kilometers.

Our solution

Special materials Research and development:

A new silica gel material has been developed, which can effectively resist the corrosion of battery electrolyte

The material has passed strict flame retardant tests, and will not melt and drip in high temperatures

Especially optimized anti-aging performance, long-term use is not easy to deformation

Advanced production process:

The innovative vulcanization process has increased production efficiency by 40%

Laser-assisted technology is used to ensure that the seal joint is perfectly integrated

Intelligent inspection system is introduced to ensure that each product is accurate and up to standard

Strict test verification:

A special testing laboratory has been established

Various extreme use environments are simulated

Completed 3,000 charge and discharge cycle tests (far exceeding industry standards)

Results of cooperation

Help customer battery packs pass the most stringent waterproof and dust proof certification

Product defect rate controlled at very low level (12 parts per million)

The cost of the bike saved 85 yuan for the customer

This model becomes the first product in the industry to pass the "double national standard" test

Customer feedback
