Aplicação do Lean Six Sigma à uma etapa do processo produtivo de conexões em PVC e CPVC com insertos metálicos

Abstract

Lean Six Sigma is a methodology adopted by several companies, whose purpose is to improve and optimize their processes and production chains. Its focus lies on eliminating waste, reducing process variation, improving quality control and reducing costs, among other benefits. This approach proves to be fundamental when seeking to improve a company's competitiveness in relation to its competitors, since its impacts extend both to the organization itself and to its consumers, aiming to deliver a high standard of quality in its products and/or services. In this context, a company specialized in plastic connections in the Santa Catarina region is committed to improving and unifying the models of metallic inserts used in connections for the PPR and Água Quente lines through Lean Six Sigma. After identifying the problem, a literature review was conducted to deepen the understanding of the relevant concepts applicable to the scenario presented. Through the bibliographic reference, some difficulties in implementing this methodology were identified, which were taken to the project through brainstorming and the best way to implement LSS in the company's context was identified. Tools such as Fmea, Doe, transport test and inverted torque test were used, which attested to the robustness and quality of the parts, which allowed their production approval. This will result in the standardization of metal insert models, and quantitative results will be presented at the conclusion of the project. Based on this, proposals for methods such as LSS training, courses and application of methodology tools were developed with the aim of reducing material costs and standardizing products and processes, resulting in financial gains for the company.
