Abstract(s)
Os plásticos são um dos materiais indispensáveis no panorama atual e que revolucionaram a indústria da matéria-prima. Precisamente por isso é uma área extremamente competitiva, e as empresas que não se destaquem, acabam por ficar para trás em comparação com a concorrência. É fulcral a aposta numa melhoria contínua, evoluindo o leque de materiais processáveis internamente, o tipo de aplicações para os componentes produzidos, a qualidade dos mesmos e diminuindo os tempos de produção de forma a conseguir corresponder a eventuais picos de procura.
O presente projeto foi realizado com o intuito de desenvolver um equipamento de rotomoldagem para a produção de reservatórios de água, sendo vital que cumprisse com a capacidade e requisitos de produção do cliente. O acordo com o cliente acerca das especificações permitiu desenvolver e dimensionar o equipamento para essas mesmas características, evitando o sobredimensionamento ou subdimensionamento.
Em relação ao equipamento, trata-se de uma Rotomoldagem Shuttle, de dois carros e braços retos, um de cada lado da estufa para tornar a produção mais eficiente. A maior carga sobre cada braço é de 1200 kg (molde + material). Para essa mesma carga no braço, o tempo de produção é de cerca de 30 minutos no forno e, posteriormente, 30 minutos de arrefecimento. Estes valores traduzem os parâmetros de produção para os moldes de maior dimensão, o que significa que, para um conjunto de moldes com outras dimensões, os valores anteriores podem alterar.
Plastics are one of the indispensable materials in today's scenario and have revolutionised the raw material’s industry. Due to this, it is an extremely competitive area in which those companies who don't stand out end up falling behind the competition. Continuous improvement is essential, evolving the range of materials that can be processed internally, the type of applications for the components produced, their quality and reducing production times to be able to meet eventual demand peaks. This project was conducted with the aim of developing a rotomolding equipment to produce water tanks, and it was vital that it met the client's production capacity and requirements. The agreement with the client about the specifications made it possible to develop and dimension the equipment for those same characteristics, avoiding over- or under-sizing. As for the equipment, it is a Rotomolding Shuttle, with two shuttle cars and straight arms, one on each side of the oven to make production more efficient. The highest load on each arm is 1200 kg (mould + material). For the same load on the arm, the production time is around 30 minutes in the oven, followed by 30 minutes of cooling. These values reflect the production parameters for the largest moulds, i.e. for another set of moulds these values may change.
