Análise do problema com uma fita alumínio na montagem de uma caixa freezer: um estudo de caso

Abstract

The creation and use of home appliances was of fundamental importance for the development and growth of the population, especially when dealing with all the white line, which give practicality in the everyday of all. The objective of this work is to understand the problem of kneading the evaporator tube in horizontal freezers, when an aluminum tape with polypropylene reinforcement is used to make the coupling of the evaporator in the inner box (refrigerator base). to suggest improvements in order to avoid this problem. The study was carried out through the Cycle PDCA tool as a basis for the organization of actions and understanding of the problem, together with technical knowledge about important factors for the application of the tape, such as adhesiveness, tensile strength, tack, of the variation in the process, such as sampling tree, variation components. For the identification and evaluation of the mechanical properties, laboratory tests were performed.The rework rate was significantly reduced and an improvement was applied in the process getting cost reduction.
