Track: Lean and Six Sigma

Abstract

This research aims to increase production capacity of wood plastic through Six Sigma DMAIC implementation, within the simulation laboratory of production of recycled plastic wood sheets of the Universidad Técnica del Norte, Ecuador. Where they simulated the conditions of the current problem, which reflects the lack of strategies to improve production capacity, and three steps were determined as project methodology based on DIMAC (define, measure, implement and control). First, the current diagnosis was carried out where it was identified that the final client has excessive waiting times for the product. With which they measured and calculated: production time in 214.3 minutes + / - 15.7, Cp=0.91 and Cpk = 0.49. Combined these results mean that production times are not suitable for the job and are off-center to the upper limit. Second, improvements were implemented from root cause analysis, which determined the lack of: maintenance, work method, training and design / construction of larger capacity molds. Third, the results were evaluated after the improvements, where a production time of 173.4 minutes was obtained, that is, an improvement of 19%, Cp=1.09 and Cpk = 0.99. These indicators mean that the production times are capable for the job and is slightly displaced to the upper limit.
