Propuesta para el mejoramiento de la productividad en la línea de plástico en una empresa de la región (Cali-Valle del Cauca)

Abstract

The present degree work relates the facts observed in the Buckets Manufacturing Processs in the company Plásticos La Esmeralda. This in order to describe, generate and interpret the results obtained in each stage of the process to develop improvement proposals in the productivity of the injection process, which contribute with the reduction of the defective product percentage in the "Baldes MilUsos Grandes" reference. Initially, a diagnostic of the current state of the proces was carried out, in which historical data of the company and data collected in field were analyzed in order to understand the behavior of the process to be able to determine if it was really being well controlled. For this, different tools were used, such as Pareto diagrams, histograms, route diagrams, among others, which served as support in the representation of information and its respective analysis. Once the diagnostic was made, the opportunities for improvement in each of the stages of the injection process were identified, as well as the noise factors that altered the normal behavior of the operations, in order to propose the improvement proposals that supply the needs of each stage. Subsequently, a study of the work was carried out in which the times used for each activity were analyzed, as well as necessary and unnecessary movements of each operation in order to make a proposal on the way of working with the objective of proposing the proposals to reduce the time cycle of the process. Finally, the design of experiments was carried out in which were identified the factors that had an important impact in the injection process. Among these factors are the mixture type, the cooling time and the injection temperature, with which the treatments or combinations of these factors are performed, in order to collect information in field about the process response variable, which in this case was the defective product percentage for “Baldes MilUsos Grandes” reference.
