Our company has a variety of different specifications of railway passenger car windows, the user can choose different sizes, styles, materials, and open ways of the window. In addition to the existing specifications, models, we can also design a new window type according to customer’s requirements. Our car window design, producing, testing are executed strictly according to the domestic relevant industry standards, the products are widely used and verified in the domestic various passenger car models .
Basic performance requirements of car window
Rain proof performance: rain test, should not appear leakage phenomenon.
Air-tightness performance: meet the overall vehicle air tightness requirements.
Water tightness performance: if the rain amount to 3L/ (M2 - min) , seepage pressure difference of ΔP≥350Pa
Resisting wind-pressure performance: deformation pressure difference P1≥3KPa
Safety pressure difference P3≥3.5KPa.
Insulation reformance: heat transfer coefficient K≤3.5W/(m².K)
Sound insulation performance: weighting sound insulation Rw≥25Db
Durability :movable window is open and close testing after 20000 times of total excursion , weighing mechanism or turnover mechanism should not invalidate , the main body of the car window is not deformed, not desoldering.
Mechanical strength: windows, fixed parts and all parts should resist with the UIC566-1990 which stipulated following acceleration level corresponding inertia load : longitudinal =5g; lateral =3g; vertical =3g (including the effect of gravity), the acceleration loads can not cause any permanent deformation of the fixed part.
