Controle de qualidade na indústria de ráfia padronização e otimização dos processos.

Abstract

This work presents a case study carried out at Ráfia Embalagens through an experimental study at the UNISC laboratory. Its subject has as base the quality control in the raffia industry, standardization and optimization of the processes with focus in the raffia extrusion, which is processed by mono-thread extruder, the “balloon” type. The work initiated with the analysis of the initial situation of the industry and evaluation of the problem. It was noticed that the main problem was the generation of residues in the process and problems with the quality control of the product. With this, data was collected through spread sheets of process control with focus on the extrusion formulation, considered a main factor in the product quality and formation of residues. With the initial extrusion formula as, we elaborated other three samples where reprocessed material was added to verify the viability of reuse and cost reduction in the industry. The samples were analyzed in the UNISC laboratory. The tests were carried out in the Emic DL 10000 equipment using norm ASTM 882 and had demonstrated viability in the addition of 1,97% of reprocessed material, presenting a reduction of 0,986% of the cost. For the management of processes tools were used as Group GAV mapping methods and tools of quality management. Moreover, a new macro-process was introduced in the organization chart of the company: the sector of training and quality control that has as objective to lead the quality control and evaluation of the processes and to promote training of the collaborators. One of the results of the study is highlighted, the proposal of a Program of Remanufacture and Mutual Support in the productive chain with the reuse of production residues in other segments as raw material.
