Estudos de casos sobre a utilização de técnicas de manufatura aditiva, em empresa de eletrodomésticos do polo industrial de Manaus

Abstract

In this work, case studies were carried out using additive manufacturing techniques in a company producing household appliances in the Manaus industrial hub, with the aim of reducing prototype production time, reducing the consumption of raw materials in the manufacture of devices, and providing designers and engineers with high­quality prototypes for validating design and concepts in their projects. Opportunities for applying the hypothesis in a PIM company were analyzed, 3D modeling of possible prototypes, slicing of 3D models, validation tests of the prototypes created. In order to demonstrate the functionality of the topic in question, 8 projects were presented, such as,1­ Base prototype of keys with air guide,2­Setup block for microwave oven cabinet bending machine,3­ Bending matrix for copper tubes, 4­ Support for air­conditioning PCB board on assembly line, 5 ­ Modification to copper tube soldering jigs,6 ­ Jigs for dimensional checking of air­conditioning copper tubes 7­ Jig for mounting fan in air­conditioning,8­ Power test jig for microwave lamps. All the projects were implemented in a company in the industrial hub of Manaus. Each project had different objectives, such as improving the assembly line process, verifying quality, reducing material costs, rapid prototyping, assembly jigs, bringing the company a financial return. The 8 case studies resulted in a gain of R$300,000.00 in avoided costs, a reduction in the time it takes to make parts from 1 week to 1 hour, with an ROI of 1348% if they were made outside the company. As a result, this work will provide cost savings, reduced manufacturing time and flexibility for project development in companies.
