Abstract
"PROCESSO PARA MOLDAR POR COMPRESSãO POLìMEROS SEMICRISTALINOS". Processo para moldar por compressão polímeros semicristalinos, compreendendo as seguintes operações: trazer o material a uma temperatura excedendo o ponto de fusão do polímero T~ F~; esfriamento do material a uma temperatura T~ I.AV~ próxima de porém mais alta do que a temperatura T~ IC~, em que a cristalização começa durante o esfriamento; alimentar quantidades dosadas de material dentro de um molde operando por compressão; formar o artigo enquanto mantendo uma temperatura próxima de T~ IC~; esfriar o artigo e extraí-lo do molde.
