Abstract

Patente de Invenção: <B>"PROCESSO E DISPOSITIO PARA PRODUçãO DE UMA PEçA PLáSTICA DE CAMADAS MúLTIPLAS''<D>. A invenção refere-se a um processo e a um dispositivo para produzir uma peça plástica de camadas múltiplas, no qual uma peça plástica injetada é revestida com ao menos uma camada de Duroplástico de dois componentes. De acordo com a invenção, a peça plástica e a camada de Duroplástico de dois componentes serão injetadas seq³encialmente em sincronismo cíclico dentro da mesma ferramenta, sendo adequado o tempo reacional do Duroplástico de dois componentes ao tempo para injeção da peça plástica. um dispositivo para produzir uma peça plástica de camada múltipla mediante utilização de uma máquina injetora, caracteriza-se pelo fato de que na máquina injetora (11) setá previsto um dispositivo RIM (13) para introdução de um Duroplástico de dois componentes em uma ferramenta injetora de componentes múltiplos. Com isto torna-se possível que a produção de peças plásticas de camadas múltiplas possa ser realizada simultaneamente através de várias ferramentas, sendo que em que uma ferramenta verifica-se o revestimento de uma peça plástica antes produzida, ao passo que em uma segunda ferramenta já é injetada uma próxima peça plástica.Invention Patent: <B> "PROCESS AND DEVICE FOR THE PRODUCTION OF A MULTIPLE LAYER PLASTIC PIECE '' <D>. The invention relates to a process and a device for producing a multilayer plastic part, in which one The injected plastic part is coated with at least one layer of two-component Duroplastic In accordance with the invention, the plastic part and the two-component Duroplastic layer will be injected sequentially in cyclic synchronism within the same tool, with the reaction time being adequate. Duroplastic of two components at the time for injection of the plastic part.A device to produce a plastic part of multiple layer using an injection machine, is characterized by the fact that in the injection machine (11) a RIM device (13) will be provided for introducing a two-component Duroplastic into a multi-component injection tool. ution of multi-layered plastic parts can be carried out simultaneously using various tools, with one tool checking the coating of a previously produced plastic part, while a second plastic part is already injected into a second tool.
