协同产品开发是提高企业竞争力的重要手段。本文探讨了协同工作模式与建模的需求，提出了一种基于对象的协同产品开发模式，包括产品信息共享、过程的集成和对象封装技术支持分阶段的协同优化决策。以注塑模具制造为背景，在并行工程框架环境下，阐明了这一协同产品开发的具体实现。
Collaborative product development is to improve the competitiveness of enterprises an important means. This article explores the requirements of collaborative work mode and modeling, and proposes a collaborative product development model based on object, which includes product information sharing, process integration and object encapsulation technology support staged collaborative optimization decision. Taking the manufacturing of injection mold as the background, the concrete realization of this collaborative product development is illustrated under the framework of parallel engineering.
