Resumen
El siguiente trabajo se realizó en la Empresa PORCONECU S.A. Ubicada en el
kilometro 19,5 vía a la costa, esta empresa dedicada a la elaboración de productos
plásticos tales como fundas y perfiles. De baja y alta densidad o de acuerdo a los
requerimientos del cliente, El motivo de esta investigación está enfocada a la gran
cantidad de Scraps ocasionada por la mala calidad de la materia prima con la cual se
está trabajando actualmente, este materia prima se analizara a cada proveedor para
determinar cuáles y quienes están vendiendo materia de baja calidad (sucia), para
realizar tales estudios nos guiaremos en técnicas aprendidas a lo largo de nuestra
carrera Universitaria como cuadros estadísticos, métodos gráficos, diagramas de
operación, diagrama de flujo, diagramas de causa – Efecto etc. Este problema causa
pérdidas de tiempo en la producción y alargue en las horas extras, conllevando esto a
pagos recargados por horas extras de trabajo, Este problema que causa pérdidas
anuales de $ 21.732,12 para ello se ha propuesto las construcción de un departamento
de control de calidad para poder analizar la calidad de la materia prima y analizar sus
componentes físico – químicos ajenos a las propiedades del polietileno de baja y alta
densidad tales como arena, aceite caucho etc. y con ello reducir considerablemente el
reproceso de los perfiles, y con ello también estaríamos bajando las horas extras
causadas por el problema del Scraps, mediante un estudio Económico se ha podido
observar que la inversión es factible ya que la inversión se recuperaría en un lapso de
tiempo de 2 años y medio aproximadamente. Y la empresa no realizaría préstamos a
ninguna entidad bancaria, ya que la inversión de nuestro proyecto no es de un valor
extremadamente alto. La empresa con recursos propios está en la capacidad de
soportar esa pequeña inversión
The following work was performed in the Company PORCONECU SA Located in the 19.5 kilometer route to the coast, the company dedicated to making products plastics such as cases and profiles. Low and high density or according to the customer requirements, The reason for this research is focused on the large Scraps amount caused by the poor quality of the raw material with which is currently working, this raw material is analyzed for each provider determine what and who are selling low-quality material (dirty) to perform such studies on techniques learned will guide us along our University career statistical charts, graphical methods, diagrams operation flowchart diagrams, cause - effect etc. This problem causes loss of production time and lengthens in overtime, leading it to recharged payments for overtime work, this problem causes losses year of $ 21,732.12 for it has been proposed the construction of a department quality control in order to analyze the quality of the raw material and analyze their unrelated to the properties of polyethylene high and low chemical - physical components density such as sand, oil, rubber etc.. and thus greatly reduce the rework of profiles, and thus we would also be lowering overtime problem caused by Scraps by an economic study has been observe that investment is feasible since the investment would be recovered over a period of time of about 2 ½ years. And the company would not make loans to any bank, and the investment of our project is not a value extremely high. The company's own resources is the ability to bear this small investment
