The crossbeam’s precise dimensions ensure perfect alignment with the vehicle’s frame and other front-end components, eliminating the need for shims or adjustments.
Its energy-absorbing design helps protect the radiator and condenser during minor impacts, reducing repair costs and downtime.
The Stamped Lower Crossbeam is produced from hot-rolled HSLA steel with a minimum yield strength of 420 MPa, sourced from certified mills. The steel is selected for its excellent formability and resistance to fatigue.
The stamping process uses advanced transfer dies with precise geometric control, ensuring consistent wall thickness and dimensional accuracy (tolerances within ±0.4 mm). All holes are laser-cut and deburred to prevent stress risers.
The Welding Square Nuts Q37106 and Q37108 are manufactured from C45 carbon steel, heat-treated to achieve optimal hardness. They are precision-tapped and inspected with go/no-go gauges to ensure thread quality.
Resistance welding is performed on automated equipment with closed-loop monitoring of current, time, and pressure, ensuring a consistent weld nugget. Each weld is subjected to pull-off testing to verify strength.
The entire assembly is cleaned, phosphated, and powder-coated with a polyester-based paint that provides over 700 hours of salt spray resistance per ASTM B117, ensuring long-lasting protection.
