Automotive Die Cutting FAQs for NEV (Power Battery)
How do your automotive die cut parts guarantee battery-pack sealing and waterproofing? Can they meet IPX7 or higher?
We select automotive-grade waterproof adhesives per your required IP rating and budget, and use one-pass forming to eliminate ooze. We support IPX1–IPX8 custom waterproofing and have passed BYD battery-pack IPX7 validation. Test reports are available.
Can your products handle the high-temperature conditions of battery packs? How is insulation performance quantified?
Yes. Operating temperature range –40°C to 160°C. Thermal-insulation materials have thermal conductivity down to 0.03 W/(m·K) to effectively block cell thermal propagation; heating parts offer ±1°C control accuracy to quickly raise pack temperature to the working range in cold environments.
Do you support large-format automotive die cut parts for battery packs? What’s the maximum size?
Yes. Up to 1.8 × 1.2 m with ±0.03 mm precision—ideal for large sealing and insulation components. We also provide structural optimization to save installation space and have delivered multiple large-format pack components for BYD.
What does the collaboration process with automakers look like? Can you support vehicle certification?
Process: requirements/drawings → technical chat group → engineering optimization proposals → drawing confirmation → free samples in 1–3 days → sample testing & certification → mass production (7–20 days) → packaging & delivery. We support full documentation for vehicle certification, with dedicated managers and 4-hour issue response.
