CAE simulation optimizes sections and structures through extrusion and testing phases. Products pass OEM compression, thermal aging, and corrosion tests with stable properties. High-strength extrusions with surface finishing ensure side-impact safety. We offer custom alloys and multi-chamber sills, with 9/10-cell designs already in mass production.

Precision fit & high weld quality. Passed crush, bending, corrosion tests – meets OEM specs for angle and yield. Integrated Al design cuts weight while absorbing energy; for 6‑series, +100 MPa strength reduces beam weight ~1.3 kg and lowers cost.

Tolerance control delivers IP67+ sealing and crush resistance. Vibration, salt spray, thermal runaway, and shock tests pass OEM battery safety specs. Full edge/end-plate/housing machining supports lightweighting; FSW/CMT welding ensures stable quality at industry-leading levels.
