Abstract

ABSTRACT: The present work has the purpose of implementing a quality control system in the different processes of the supply department in the company Sedemi S.C.C. such as: thermal cutting, drilling, beveling and bending of A36 steel plates. The quality assurance and control in the different processes begins in the supply area since it is the one that provides raw material to the assembly and welding areas, non-conforming elements in the supply area generate delays in production or reprocesses that involve a higher production cost to the company. The batch size is defined in each process in the supply area and with the help of the NTE INEN ISO 2859-12009 standard, the minimum sample size is established for each production batch in the different areas, based on the established by the company is defined as Acceptable quality level (AQL, for its acronym in english) of 5% as the initial control point since by trial-and-error methods it was defined that it is the percentage of failure of elements in the area of abstention. National and international quality control standards are defined in each process within the supply area, the ideal sample size for each production batch and thus reduce reprocessing in the plant, projecting savings in it in the next 3 years. as a bonus.
