This article summarized the main results of the statistical control carried out on the production of poles for aerial networks in the Impregnation Plant located in the Macurije Agroforestry Company in the province of Pinar del Río. This was done in view of the need to identify the nature of the causes of quality defects in the posts for aerial networks. Consequently, the objective of this article was to assess the quality defects in the posts for aerial networks of the impregnation process in the Impregnation Plant, identifying their main causes. For statistical control of quality defects, control graphics were used for attributes, specifically Control Charts for the number of defects per unit or U charts and Poisson Capacity Analysis using the Minitab 17.0 software, in the same way it was used the Tree of Current Reality for the identification of root causes. From the diagnosis made, it was observed that posts were impregnated that not complying with quality indicators and demand, causing customer dissatisfaction, while it was identified that the root cause of the defects was deficiencies in the productive process.

Keywords : statistical control; quality defects; control charts; impregnation process; productive process..
