Abstract: In an injection moulding process, the mould cooling system is very important for both the part quality and productivity. Due to the complexity of the cooling process and the lack of cooling methods, moulding processes are often operated under lower productivity and quality levels. To achieve optimal cooling effect, this research focuses on the following three aspects: (1) Two models applying finite element method in mould cooling and thermal stress analyses were developed and proven to be reliable. (2) The a??Ua??-shape milled groove and milled groove insert methods were proposed for medium to large and complex moulded parts. Although the methods are more expensive, their benefits including higher productivity and part quality are very attractive. (3) An algorithm of surface offset was developed to facilitate the auto-design of cooling systems with the proposed cooling methods. Based on the cooling analysis, optimisation algorithm was proposed utilising the characteristics of auto-design.
