This paper proposes a cloud-based manufacturing knowledge sharing system for injection mould redesign (IMR) based on blockchain technology. In our proposed system, private cloud is used to store the IMR knowledge, and blockchain provides standards and protocols for implementing the system as well as ensuring the security in a trustless environment. K-Nearest Neighbors is used for retrieving the blockchain-based document knowledge. The proposed system not only can facilitate injection mould redesign, but also provide a mechanism for knowledge owners to share their own assets securely.
