ANÁLISE DE VARIAÇÃO DE PRESSÃO NO PROCESSO DE EXTRUSÃO NA FABRICAÇÃO DE NÃO TECIDOS

Abstract

The work regarding the analysis of pressure variation in the extrusion process in the non-woven factory has the purpose of understanding the reasons for the pressure variation between bundles, which are identical, this anomaly causes losses in the company's billing since it was necessary to stop of all machinery to change matrices only once every two months and nowadays this activity has been happening once every month. The cause and effect diagram was used to identify the anomaly where problems such as variation of machine parameters, defects in control and measurement devices, errors in the cleaning procedure and matrix changes and poor quality in the raw material are discussed carefully.
