METHOD OF MAKING AN AUTOMOTIVE TRIM ASSEMBLY HAVING AN INTEGRATED AIRBAG DOOR

摘要

A method of making an automotive trim assembly includes injection molding a first curable polymer to form a substrate including a deployment door in a first shot of a molding operation. A cover is then formed on at least a portion of both the substrate and deployment door by injection molding a second curable polymer in a second shot of the molding operation. The cover includes an inner and outer layer of the second polymer having a substantially non-cellular structure and a core of the second polymer having a cellular structure between the inner and outer layers. At least one score line is formed in the substrate to define the deployment door therein. The score line may be formed during the molding operation or in a post-molding process, such as a laser scoring process.
