Adaptive Headlight Gear Mechanisms

Modern automotive designs provide more safety and control for users, including active braking systems, active lane control and active headlight systems. Active headlights simply position the light beam in the direction that the vehicle is turning, providing improved and safer visibility. The systems work by small electrical motors physically moving the headlight light source which then turns small Delrin® acetal gears. The dimensional precision, low wear and friction and mechanical strength that Delrin® provides make it’s a superior material for this application.

Compared to acetal copolymer, Delrin® acetal homopolymer offers higher tensile strength, stiffness, creep and fatigue resistance, and significantly higher impact resistance. The extra mechanical properties of Delrin® allow for parts to be made thinner and smaller, whilst delivering the same performance of a thicker, less compact copolymer acetal moulding.
