This industrial process requires the manufacturing of metal moulds using complex heating and cooling systems. The purpose of this research is to optimize both the plastic injection moulding process and the mould manufacturing process itself by combining practices in this industry with current additive manufacturing technologies, specifically Wire Arc Additive Manufacturing (WAAM) technology. A mould punch was manufactured by using both WAAM technology, whose internal cooling system has been designed under the concept of Conformal Cooling, and conventional cooling channel designs and manufacturing techniques in order to carry out a comparative analysis. Theoretical results obtained by CAE methods showed an improvement in heat extraction in the WAAM mould. In addition, the WAAM mould was able to achieve better temperature homogeneity in the final part, minimizing deformations in the final part after extraction. Finally, the WAAM manufacturing process was proven to be more efficient in terms of material consumption than the conventional mould, reducing the buy-to-fly ratio of the part by 5.11. info:eu-repo/grantAgreement/ES/DGA/T08-20R info:eu-repo/grantAgreement/EC/HORIZON EUROPE/101136940/EU/A sustainable approach to remanufacturing/COMPASS info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 4.9 2024 POLYMER SCIENCE 19 / 94 = 0.202 2024 Q1 T1 0.918 2024 Polymers and Plastics 2024 Q1 Chemistry (miscellaneous) 2024 Q1 9.7 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Dieste, Jose Antonio Universidad de Zaragoza (orcid)0000-0001-7178-4285 Monzón, Iván Laguía, Alberto Gracia, Pascual Javierre, Carlos Universidad de Zaragoza (orcid)0000-0002-8008-4819 Clavería, Isabel Universidad de Zaragoza (orcid)0000-0003-4230-7900 Elduque, Daniel Universidad de Zaragoza (orcid)0000-0001-9137-3387 5004 545 Universidad de Zaragoza Dpto.
