Abstract(s)
A atual conjuntura, aos mais variados níveis, quer nacional quer internacional,
tem levado empresas das mais variadas áreas a procurar novas formas de se manterem
competitivas e eficientes.
Este projeto, inserido no contexto de uma empresa distribuidora de perfis de
alumínio para caixilharia, a ALEDI – Comércio de Alumínios, Lda., pretende desenvolver
a partir de um dos vários produtos existentes, um novo sistema de batente de caixilharia
em alumínio com rotura térmica que esteja ao nível dos mais recentes avanços e
exigências do setor, ao mesmo tempo que permita à empresa consolidar a sua atual
posição no mercado e dispor, pela primeira vez, de um produto exclusivo. O aumento
da oferta por parte da concorrência, de sistemas cada vez mais variados em termos de
medidas de largura, obriga à redução dos incrementos entre as medidas dos produtos
existentes. Assim, não interessa desenvolver apenas mais um sistema semelhante aos
existentes, mas sim desenvolver um sistema que ocupe uma posição específica no
mercado.
O trabalho é iniciado pela pesquisa dos produtos já existentes no mercado,
avaliando os condicionamentos das leis e regulamentos e dos processos de fabrico
disponíveis, de forma a obter a estrutura base e a lista de pontos críticos a abordar no
desenvolvimento do sistema.
A pesquisa é complementada com a abordagem aos departamentos técnico e
comercial da empresa, sob o escrutínio da gerência desta, para confirmar e delinear
quais os pontos críticos que necessitam de melhoria ou alteração no projeto do novo
sistema. É assim definido que o desenho dos novos perfis será focado na melhoria do
canal de drenagem, de forma a prevenir eventuais infiltrações e a corrigir problemas já
evidenciados nos atuais sistemas.
O projeto é tornado prático através do esboço e posterior desenho técnico dos
novos perfis e da análise de compatibilidade com as tipologias pretendidas, ferragens
existentes padronizadas e já certificadas e com os métodos de montagem disponíveis
por parte dos clientes da empresa. É assim decidido que a criação dos novos perfis se
deve então basear no sistema mais vendido pela empresa, a partir do qual se irá
desenvolver um novo com maior largura de base.
O aumento da medida de largura do sistema permite, para além da total
remodelação dos canais de drenagem, um aumento da medida das caixas de esquadro
de aperto e da largura destes, ação que permite fortalecer as uniões das esquadrias. É
também consequência do dito aumento de largura dos perfis, a necessidade da
utilização de outro formato de poliamida e de vedação central.
Concluído e aprovado internamente o desenho final dos perfis necessários é
realizado, externamente, pela empresa de extrusão o desenvolvimento e produção das
matrizes. Estas permitem obter, na forma de barras de alumínio, os perfis desenvolvidos que são depois sujeitas a análise e verificação das suas cotas por comparação com os
desenhos técnicos dos mesmos.
A lacagem e cravação dos perfis, e a sua posterior montagem com os acessórios
e ferragens existentes, permitem verificar a correta funcionalidade e compatibilidade
dos perfis, levando o projeto à sua conclusão e à obtenção de um novo sistema.
ABSTRAC: The current situation, at the most varied levels, both nationally and internationally, has led companies from the most varied areas to look for new ways to remain competitive and efficient. This project, within the context of a company that distributes aluminum profiles for frames, ALEDI – Comércio de Alumínios, Lda., intends to develop from one of the several existing products, a new aluminum casement window system with thermal break that is in line with the latest advances and demands of the sector, while allowing the company to consolidate its current position in the market and have, for the first time, an exclusive product. The increase in the offer, on the part of the competition, of systems that are increasingly varied in terms of width measurements, forces the reduction of increments between the measurements of existing products. Thus, it is not just about developing a system similar to the existing ones, but rather to develop a system that occupies a specific position in the market. The work begins with researching products already on the market, evaluating the conditionings of laws and regulations and the available manufacturing processes, to obtain the basic structure and the list of critical points to be addressed in the development of the system. The survey is complemented with an approach to the company's technical and commercial departments, under the scrutiny of its management, to confirm and outline which critical points need improvement or change in the new system design. It is consequently defined that the design of the new profiles will be focused on improving the drainage channel in order to prevent possible water infiltrations and correct problems already evident in the current systems. The project is made practical through the sketch and subsequent technical drawing of the new profiles and analysis of compatibility with the intended types of windows, existing standardized and certified hardware accessories and with the assembly methods available to the company's customers. It is therefore decided that the creation of the new profiles should then be based on the most sold system by the company, from which a new one with greater base width will be developed. The increase in the width of the system allows, in addition to the total remodeling of the drainage channels, an increase in the measurement of the tightening joint boxes and their width, an action that makes it possible to strengthen the joints of the window frames. It is also a consequence of the said increase in the width of the profiles, the need to use another polyamide format and a new central seal. Once the final design of the necessary profiles is concluded and internally approved, the development and production of the dies is carried out externally by the extrusion company. These make it possible to obtain, in the form of aluminum bars, the developed profiles, which are then subject to analysis and verification of their dimensions by comparison with their technical drawings. The lacquering and mechanical crimping of the profiles, and their subsequent assembly with the existing hardware accessories, make it possible to verify the correct functionality and compatibility of the profiles, taking the project to its conclusion and obtaining a new system.
