Automotive Fuel Filler Door Mold

Reliable sealing and flush exterior fitment depend on precise mold cavity geometry for automotive fuel filler doors. The tooling shown manages the interface between the outer cover and inner structural frame, ensuring consistent gap control and preventing wind noise or water ingress in vehicle applications.

This injection mold configuration addresses complex undercuts and dual-material interfaces typical of exterior trim components. Manufacturing relies on high-precision CNC machining and EDM to define sharp parting lines and smooth surface finishes, while integrated hydraulic cylinders facilitate side-core pulling for intricate latch mechanisms and hinge mounting points.
