Abstract—Metal mechanics plays a relevant role in the entire
productive structure of the economy since it is an indispensable
supplier of capital goods such as equipment, infrastructure,
spare parts, and machines. However, the lack of efficient
production processes, the high rate of defective products, and
unnecessary routes in factories and production workshops are
some of the frequent problems that companies in this area have
that directly affect their productivity. Consequently, extreme
routes and the profiling area have been identified as the main
bottlenecks in the production process, impacting production
efficiency. Therefore, the main objective of this case study is to
demonstrate how the implementation of Lean tools has managed
to increase the efficiency of the process for the production of
thermoacoustic panels, reducing unnecessary routes and
defective products. The proposed model comprises Lean tools
such as the standardization of work and the 5S methodology and
the Systematic Layout Planning (SLP) was also applied to carry
out the redistribution of activities. A simulation was carried out
in the Arena software to validate the improvement proposal’s
results. The results obtained from the simulation were an
increase of 19.24% in the overall efficiency of the process, a
decrease of 42.4% in hours lost due to defective products, and a
26.7% reduction in downtime.
