Abstract: The characteristics and process characteristics of the thin-walling of the slush molded instrument panel skin are expounded,and the differences in production and use of raw materials are compared with those of the old type. Through the debugging of production equipment,relevant quality testing project experiments,and long-term mass production,it has been verified that the use of thin-walled skins can achieve the application effect of weight reduction and cost reduction for the whole vehicle,providing a theoretical reference for the lightweight development of the production process of slush molded instrument panel skin in the future.

Key words: slush molding, instrument panel skin, thin-walling, quality measurement and management
