Estudio de caso para determinar la incidencia del SCRAP en la productividad del área de Peletizado de Plásticos Industriales C.A.

Abstract

The present investigation was raised with the objective of determining the factors that influence in the increase of level of Scrap of the area of pelleting of the plant of Industrial Plastics C.A. to propose a plan to increase productivity by applying the Six Sigma methodology. The descriptive, deductive and quantitative methodology was applied, with application of the Six Sigma methodology, whose results indicated that during the first three phases of the Six Sigma tool, they determined that the causes that cause high levels of scrap in the PICA plant, for over 5%, they were associated to the production of formulas with calcium carbonate, presence of contaminated material in the mixture of materials, leakage of materials by heads in poor condition, plugging of meshes and wear of mechanical seals of the head of the pelletizer, The high level of scrap is related to economic losses that amounted to $ 29,118.15 annual. It was proposed to execute improvement plans for the pelleting process, among whose alternatives the replacement of the current raw material (polyethylene) was considered, for raw materials that maintain the performance of the finished product, the creation of the procedure of change of meshes and mechanical seals of the pellet head, so that scrap levels can be minimized below 3.39%. In conclusion, the application of Six Sigma helped reduce the loss and boost productivity in the PICA pelletizing plant.
