Melhoria de processos e qualidade no produto final de um caracol transportador de sementes

Abstract

When you want to transport some material in industries or on agricultural machinery, such as bulk grains, one of the most used components is the snail. This component can be manufactured by cutting, welding and assembly processes or even by injection process. The component under study will be used to transport and homogenize the seed treatment in a seed treating machine. Therefore, the aim of this work was to improve the manufacturing process and product quality, developing a new way of manufacturing the component. The study of the new snail project was carried out in an agricultural company. The current welding manufacturing process presents greater challenges between the processes, together with the results obtained from times and difficulties during manufacturing, a new manufacturing proposal was analyzed and presented, which consists of replacing welded parts with injected assembled. As a result, a higher cost of raw materials for manufacturing was considered, but ensuring easier parts for manufacturing and replacement, resulting in a more optimized design of manufacturing processes, reducing operating time and labor. Compared to the previous project, the new project requires 4.86 kg less of the steel material, but uses 18 more operations of the injection process, which represents an increase in cost per complete unit. After testing for approval, the component was implemented on the production line where good performance was achieved within the pre-determined objectives.
