MELHORIA DE PROCESSO: estudo de caso no retrabalho na injeção de termoplástico

Abstract

This work aims to present, analyze and evaluate the result of the rework process at the injection point in a frame of a card machine, where automatic cutting by the robot was implemented, removing the manual process, as it was causing the shipment of non-working parts. reworked to the customer, which consequently opened complaints for corrective actions in the process. To make the project viable, the quality tool Ishikawa Diagram was used, which shows the causes in the process that cause the sending of non-conforming parts to the customer, when the manual deburring process is used. The goals were achieved, as can be seen in the number of customer complaints before and after the implementation of the automatic process. With the improvement, the process is able to produce more parts per hour, generating a cost reduction for the item's production, as the process cycle was reduced, generating more parts per hour.
