Resumen

There are immeasurable small and medium-sized companies distributed throughout the world that in some cases have certain occupational and financial limits. In turn, these contribute significantly to the economy of each country. Within the main sectors that make up, these so-called SMEs are metal-mechanic manufacturing. One of the main problems faced by these manufacturers is the production of defective parts in their production lines, this has a great impact on billing, whether monthly or annual. For this reason, this present investigation proposes an innovative solution attacking the aforementioned problem. This, using various analyzes related to the lean philosophy and its tools that help to counteract this dilemma. This study seeks to implement tools such as 5S, Poka-Yoke, Andon and TPM, in order to reduce defective production in the hinge line of a Peruvian metalworking SME. Through the investigation, a progress result of 29.83% to 13.24% was obtained in its defective production indicator, which is reflected in a margin of improvement of 16 percentage points.
