The automotive door moisture shield is located behind the trim panel on an automotive door. It is designed to prevent moisture from leaking into the circuit device inside the door, and thus, protect the automotive electrical components. The edge of the water shield is attached using a butyl sealant, which also protects against dust, oil and dirt.
PE film, IXPE foam. Other materials can be customized as needed
Thickness 0.03 ~0.5mm. Weight, shape and size specification can be customized.
The product is shaped using a vacuum forming machine, which is used after film blowing, and then attached using a high frequency welding machine.
Note: We have ready-made molds of the above types, which can be manufactured and processed quickly. If customers can’t find the type they need, simply contact us, and we will customize to meet your needs.
