Abstract: Under the circumstances of plastic material’s diversity and the difficulty of material selection, the material data classification method and the relation of material property and the plastic part are studied, and a general database which including material property, melt plastic flow behavior, plastic configuration, and pigmentation libraries is set up. “Material property – plastic structure factor” mapping mechanism is created according to the material property influence on the plastic product. The mapping tool can automatically solve the mutual influence and requirement between material property and plastic structure factor. The general inquiry navigator is developed to search the associated information of the material selected, and export the selected information to several formats for share. It showed that this system can solve the problem of multipurpose plastic material selection fairly well.

Key words: material property, database, associated query, plastic part structure factor
