Proposta de redução de paradas de produção de uma indústria de fornecimento de borracha no sul do Brasil

Abstract

The globalized world has intensified competitiveness among companies. Organizations that want to gain a prominent position need to control their productive processes. Production and productivity have a great influence on achieving good results. Production downtimes are problems that affect many organizations, and they interfere in the production and quality of the finished goods. A company will achieve great results while maintaining the availability to produce from its machines and equipments. To explore this theme, this study aims to propose actions to reduce downtimes in a production line of a rubber supply company in the South of Brazil. The process studied refers to the manufacturing of rubber blankets. Two tools were applied in the methodology: the Pareto chart was used to analyze the data, and the 5W2H method was applied to understand the root causes and propose actions to reduce them. This company did not have an adequate system to control these downtimes. About 47% of the failures that have been recorded prior to the execution of this study could not be identified. Thus, a reformulation of the current system was suggested according to categories that are more appropriate. The main suggested actions to reduce production downtime in this company were: better scheduling of cleaning and maintenance activities, taking turns at meal times, changing the parameters and processing conditions of the rubber, doing a study to reduce the setup time, and scheduling engineering tests at the most addequate times. Simple actions can reduce production interruptions, and it does not always require large investments. The main potential to reduce downtimes is 68% in this rubber supply industry. This study reinforces that simple and cheap actions can also generate effective results.
