摘要：Disclosed is a joint structure for a partial foaming part of an instrument panel,which is capable of preventing loss of materials due to unnecessary consumption of theskin layer and leakage of a polyurethane foam filled between the core layer and the skin
layer during partial foaming of the instrument panel. In a joint structure between a corelayer and a skin layer for manufacturing a partial foaming part of which a polyurethanefoam layer is formed between the core layer and the skin layer , a partial end portion iscurved inwards within the polyurethane foam layer at a front end of the skin layer . A skinend portion upwardly extends from an end of the partial end portion and is pressedagainst the core layer due to foaming pressure of the polyurethane foam layer . A foamstaying space is provided between an inner side surface of the core layer and the skin endportion of the skin layer . Flow control walls ′, for preventing a polyurethane foam frombeing overflowed directly between the inner side surface of the core layer and an end ofthe skin layer , downwardly is foamed from an inner upper surface of the core layerabove the joint part of the core layer and the skin layer
