Improvement proposal based on lean manufacturing to reduce defective rate in an SME in the optical sector

Abstract

The present research work will focus on medium and small companies in the optical sector, the most recurrent problems of a specific company will be identified, where these results will be compared with the current problems of the sector in general to identify the main problem. The aim of this research project is to reduce defective products in the production process and thus increase utility net of the laboratory. To achieve this goal, it is necessary to reduce operator errors, avoid machine failures and optimize process flow. In order to be able to carry out all of the above, it was considered necessary to implement the 5S, standard work, jidoka, TPM and poka-yoke tools. In the present work, the defective rate decreases to 1.40 %, previously this indicator was 8.22 %.
