Propuesta de mejora continua para reducir el nivel de SCRAP en la elaboración de rollos en una industria de manufactura de empaques flexibles

Abstract

In the company Plastisec S.A, there has been an increase in the percentage of scrap since 2021, a review of the production reports is conducted, identifying an average of 3.13% scrap. For this reason, the management takes the initiative to raise an improvement project to reduce this percentage, for which the DMAIC tool was used to identify the variability of the process and implement improvements within it. Under this premise it was possible to identify the problems associated with the treatment of the films, the trimming within the line and frequent changes of materials that cause loss of virgin material. Therefore, shortcomings in the visualization of information within the production planning were identified with the production department and corrected by implementing a matrix of treated areas and the creation of product codes that allowed the planner to order the jobs due to their degree of difficulty and generating less variation in temperature changes associated with job changes, with these implementations it was possible to save $7,288.92 in July.
