ANÁLISE DA EFICIÊNCIA DOS TRATAMENTOS DE SUPERFÍCIE EM PEÇAS PLÁSTICAS PARA APLICAÇÃO DO PROCESSO DE TAMPOGRAFIA

Abstract

This work focuses on an analysis of the process of tampo printing in plastic parts of electronic devices in a company with the lean manufacturing system, analyzing and comparing the different forms of surface treatment and thus, get the best process, in order to avoid waste of defective parts, and consequently time and money previously invested in the process. Such an approach is necessary due to the fact of printing on plastic parts is indirectly in people’s daily life at all moment. Therefore, analyzes and improvements in the process must be constant to ensure a good quality in the product for longer periods. The objective of this work is to present the use of tampo printing on thermoplastic, demonstrating the various surface treatment process of the parts before the tampo printing. For the achievement will be made a theoretical study about different surfaces treatments used in the process of tampo printing taking to account the advantages and disadvantages of each process. Posteriorly will be carried out practical tests of printing in a same number of samples for each process and thus, analyze of the results of 2 different process. The surface treatment process that will be compared are: the corona and plasma. After data collection of the 2 processes such as productivity, number of defects, cost and final quality of the product, these will be evaluated and compared to thus conclude the work, presenting the advantages and disadvantages of each process.
