Resumen

This article addresses the issue of low efficiency and high overhead costs in a small metalw working company (MYPE) in Peru specializing in the manufacturing of metal formworks. Currently, efficiency ranges between 65% and 70%, leading to elevated costs due to additional labor, which accounts for approximately 3% of monthly revenue losses. To enhance performance, the implementation of four key engineering tools is proposed: Total Productive Maintenance (TPM), focused on a preventive approach; the 5S methodology, to organize the work environment and reduce unnecessary operator movements; Systematic Layout Planning (SLP), to increase operational efficiency by redesigning production areas; and Single-Minute Exchange of Die (SMED), to reduce setup times. The combination of these methodologies aims to boost operational efficiency to 85%, reduce costs, and improve the company’s ability to meet demand more competitively, with a projected payback period of one year. This comprehensive improvement approach is presented as a fundamental strategy to enhance the company’s competitiveness and sustainability within the Peruvian metalworking context. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2026.
