• 1. Material: Choose ASA or PC/ABS, resistant to -40-120 ℃, resistant to high and low temperature deformation and weather resistance, suitable for the interior environment of the car.
• 2. The damping block of the knob is equipped with staggered tooth grooves, which can store water vapor and control deformation. The pulling force is ≤ 2N, and the operating feel is consistent; Pin hole interference fit with 0.03mm force transmission to prevent abnormal operating force.
• 3. Structure: The blade spacing is ≤ 6mm. When closed, the overlap between the blades and the shell is ≥ 2mm, with a gap of 0.5-1.5mm. There is no air leakage and it is silent.
• 4. Layout: The distance between the midpoint of the grille and the H-point is ≥ 356mm, and the airflow covers the passenger area to ensure cooling and heating effects.
• 5. Aesthetics: The hot stamping surface is raised, with rounded corners R ≤ 0.5mm, and block hot stamping prevents air bubbles; Can be done in high gloss/matte, matching the interior style.
