High-Mounted Stop Lamp (HMSL) Protective Cover Two-Shot Mold with Rubber Coating

Structural Characteristics and Shape Design
The guard panel features an elongated curved profile that matches the mounting surface on the vehicle roof or tailgate area. The main body is molded as a rigid structure, while selected edges and corners are overmolded to create a softer transition, improving fit and reducing the risk of interference with adjacent components during assembly.

Overmolding Process and Protective Functions
An overmolding process is applied after the rigid substrate is formed, precisely covering designated areas with a secondary material. The overmolded zones can provide edge protection, cushioning, and auxiliary sealing support, helping reduce looseness, noise, or scratching caused by assembly tolerances. Clean and stable material interfaces support a consistent appearance.

Mold Design and Molding Control
To meet the surface quality and clear overmold boundary requirements for exterior trim/guard parts, the mold is optimized in parting line placement, gate layout, and overmolding alignment features. Flow path and venting are designed to ensure uniform filling and neat boundaries, improving consistency and yield in mass production.

Application and Integration
This overmolded guard panel is suitable for appearance transition and protection in HMSL assemblies. The structure can be adapted to different vehicle mounting curvatures and boundary requirements, while maintaining mold manufacturability and stable serial production for long-term supply.
