Estudo de caso de método da manutenção produtiva total em máquina de tingimento de tecido contínuo

Abstract

With the advancement of the Industry 4.0 concept, many companies have sought to improve their production through new technologies and the adoption of methodologies that make processes more efficient with better management and waste reduction. To achieve this, companies have embraced Lean Manufacturing, which aims at eliminating waste. Among the key techniques of this system is Total Productive Maintenance (TPM), which aims for zero failures and zero breakdowns of machines, alongside zero defects in products, zero losses in processes, and zero accidents. The Specific Improvement (SI) Pillar aims to maximize Overall Equipment Efficiency (OEE) by eliminating losses. Therefore, the SI Pillar initiates an improvement group to implement a tool called Break Reduction Roadmap on a dyeing sector machine, the Pad Steam (PS) III. The objective is to reduce the quantity and time of breakdowns due to corrective actions in critical areas of the PS III. With the application of this method, there was approximately a 61% reduction in the machine's physical unavailability, leading to an increase in OEE, improved productivity, and a reduction in non-quality.
