If the bezel compresses the foam and trim cover, the amount of interference is usually equal with the thickness of the plastic part installed. Alsoo, consider a line to line interface of the plastic part with the foam pad. These considerations also depend upon the styling and customers requirements.-A 15 mm minimum of trim is required underneath the plastic bezel.-The foam must be designed to take the shape and accommodate the plastic bezel, but a minimum of 20 mm thickness of the foam is required between the bezel and the structure. Plastic parts design training——座椅塑料件设计 inslalled directly against the structure, at nominal we must have the carpet covered with the plastic part for a dimension of 10 mm minimum (12 mm at corners). The maximum dimension of the carpet covered by a plastic part is based on the size of the opening and on the testing required by the customer (load floor, ingress/egress, etc.). 地毯盖板 Plastic parts design training——座椅塑料件设计 Plastic parts design training——座椅塑料件设计 Plastic Part Design Guidelines These guidelines are only for reference ，Please don’t spread abroad.

Rather, the rubbing action is smaller and more semi-circular in nature, with the fabric working around the shields edge locally. Plastic parts design training——座椅塑料件设计 Draft angles and shut-o
