Abstract: Design data is the source data of product lifecycle in manufacturing enterprise.
Design data standardization largely determines the effect of the application of PLM systems.
Accordingly, the study of materials information generation in the design process, materials
information and transmission process in the PLM system, and how to build a single data source
between design tools and PLM system are conducted. The construction and implementation of the
standard library system oriented to the PLM are put forward. Collaborative application between the
design tools and PLM system is achieved. The standard-parts library system based on the theory and
the method has been developed in the SOLIDWORKS software platform and has been applied in the
design department of a manufacturing enterprise. The effect of the application is obvious.

Key words: PLM, standard-part library, material, single data source, SOLIDWORKS
