Statistical quality control in MSMEs of recycled plastic wood

Abstract:

The application of statistical quality control in plastic wood MSMEs in Ecuador is the first implementation carried out for this productive sector. Where the fundamental problem is the variation of the results of recycled plastic wood in tensile analysis, where the coefficient of variation is 51.38% with a maximum force of 605.42 N. In this case study, the methodology composed by the diagnosis Current of the production process, the identification of qualitative-quantitative variables and the implementation of statistical quality control. I provoke the standardization of the productive process in the criteria of selection of recycled plastics, optimum values of temperature, pressure and time in each of the subprocesses. Thus, improvements were obtained in the tensile analysis of recycled plastic wood where the coefficient of variation after the improvement is 7.26% with a maximum force of 751.03 N.
