High Mount Stop Lamp (HMSL) Mold

High Mount Stop Lamp (HMSL) Mold

High Mount Stop Lamps (HMSL) are critical safety components designed to provide clear and immediate braking signals to following vehicles. Positioned at an elevated location, HMSLs significantly improve reaction time and reduce rear-end collision risks.
HMSL components typically feature compact structures, high brightness LEDs, and clear or red lenses, requiring molds with excellent dimensional accuracy and consistency. Uniform light output and reliable assembly are essential for compliance with automotive safety standards.
We specialize in HMSL mold design and manufacturing, focusing on thin-wall molding, stable light transmission, and efficient production performance. Precision machining and optimized mold structures ensure high repeatability and low defect rates in mass production.
Durable mold steels such as NAK80, 1.2343ESR, and 718H are selected to ensure long mold life and stable performance.
Our HMSL mold solutions are widely applied in passenger vehicles, SUVs, and commercial vehicles, supported by technical assistance, mold maintenance, and after-sales service.
