This paper provides a systematic and quantitative method for the analysis of the economical break-even between steel and aluminium moulds used in the injection moulding process. The proposed approach takes into account both mould manufacturing (material purchase and machining) and injection moulding costs (cycle time). Thermoplastic material cost is not considered since it does not change in a comparative analysis. The total costs are estimated against the part life volume and the break-even point between steel and aluminium technological solution is determined. The proposed method is validated through an industrial case study.

Abstract
This paper provides a systematic and quantitative method for the analysis of the economical break-even between steel and aluminium moulds used in the injection moulding process. The proposed approach takes into account both mould manufacturing (material purchase and machining) and injection moulding costs (cycle time). Thermoplastic material cost is not considered since it does not change in a comparative analysis. The total costs are estimated against the part life volume and the break-even point between steel and aluminium technological solution is determined. The proposed method is validated through an industrial case study.File in questo prodotto:
