A Brief Review of Injection-Mould Materials Hybrid Manufacturing Processes

Injection moulds play a vital role in manufacturing plastic and light alloy’s metallic parts. However, these moulds face a significant obstacle in wear and tear, including the formation of cracks, due to the high temperatures and pressures present during the production process. In this paper, hybrid manufacturing processes will be summarised in a brief review, and how each of them influences the surface of the injection moulds will be discussed. To facilitate researchers’ comprehension of the subject matter, the selected timeline ranges from 2018 to 2023. Having 24 references as a limiting factor, each hybrid process is documented by two or three outstanding reviews or research papers. The primary search terms employed to gather information were “AM”, “Copper-Beryllium alloys”, “Heat-Treated Steels”, “Hybrid processes”, “Invar-36”, “MAF”, “TAM”, “Tool-Wear”. Their combination enabled to find information about the evolution of injection-mould materials and hybrid machining technologies. Despite advancements in various techniques, some methods still have not been fully utilised or explored. Although it has been established that conventional processes have their benefits, it has also been discovered that specific non-traditional methods possess notable advantages.
