Enhancing machine availability in plastic SMEs through lean and TPM: evidence from a peruvian case study
… in Peru faces significant challenges related to machine downtime and prolonged set-up times, which limit productivity and increase operational costs. Previous studies have highlighted the benefits of Lean Manufacturing and Total Productive Maintenance (TPM) for improving equipment efficiency, yet …

Improvement of service level through lean tools in a plastics manufacturing company
… of 416.20 h per month in the injection molding machines. This paper proposed model based on the application of two lean tools: the 5S methodology and planned maintenance. The implementation of this model showed significant improvements: the incidence of lost products was reduced to zero, machine …
