Abstract

1/1 resumo "método para a moldagem por injeção a pressão baixa substancialmente constante" é apresentado aqui um método de moldagem por injeção a pressões de fusão substancialmente constantes baixas. as modalidades do método apresentado possibilitam um método de moldagem por injeção que é mais eficiente, sob o ponto de vista energético—e de custo— do que os processos de moldagem por injeção a alta velocidade convencionais. as modalidades do método apresentado permitem, de modo surpreendente, o preenchimento de uma cavidade de molde a baixa pressão de fusão sem endurecimento prematuro indesejável do material termoplástico na cavidade de molde e sem a necessidade de manter uma temperatura constante ou a cavidade de molde aquecida. até o momento, não era esperado que um método a pressão constante pudesse ser executado a baixa pressão sem o endurecimento prematuro do material termoplástico com o uso de uma cavidade de molde não aquecida ou cavidade de molde resfriada.
