Optimization of Flow Test Quality Indicators in a PIM Air Conditioner Line

The present article aims to describe the process of detection by flow measurement in a window air conditioner refrigeration system of a company of the Industrial Pole of Manaus PIM. The equipment used is a flow sensor model SFAB-200U-HQ8-2SA-M12, which was installed in a production line, connected to a supervisory system, which will indicate through a visual device Andons, the approval of the product in real time . The process occurs through the sending of flow data, with the early detection of capillary blockage, ie, before the final assembly of the product, the objective is to optimize the quantity of products reworked internally, which will cause an increase in the indicator of FPY (First Passed Yield), as well as a reduction in field failure rates due to the non-detection of capillary obstruction in the process. For this, it was necessary to identify the normal flow of product, and to define new parameters of approval, next to this the methodology 6 sigma was applied to make the analysis of the data.
