Abstract

SE MOLDEA UNA PIEZA PLASTICA DE UN PLASTICO CON UN CUERPO INTERNO (44) DE PLASTICO CRISTALINO Y UNA CAPA SUPERFICIAL EXTERIOR (46) DE PLASTICO AMORFO. LA CAPA SUPERFICIAL AMORFA SOPORTA LA CARGA DE FRICCION, AL MENOS, DURANTE UN PERIODO DE RODAJE INICIAL. EN UNA REALIZACION, SE FORMA LA CAPA SUPERFICIAL UTILIZANDO UNA TEMPERATURA DE FUSION MAS ALTA DEL PLASTICO Y/O UNA TEMPERATURA DE MOLDEO INFERIOR A LA NORMAL. EN OTRA REALIZACION, SE MOLDEA UNA PIEZA INTERMEDIA COMO PIEZA INTERMEDIA CRISTALINA Y SE CALIENTA UNA CAPA SUPERFICIAL Y SE ENFRIA RAPIDAMENTE PARA FORMAR LA CAPA SUPERFICIAL AMORFA EN LA PIEZA FINAL. SE MOLDEA UNA CAJA DE COJINETES (28) INYECTANDO LA MASA FUNDIDA PLASTICA EN UN SOLO PUNTO INTERMEDIO RESPECTO A LOS EXTREMOS DE UNA SOLA BARRA (34) DE LA CAJA DE COJINETES PARA PERMITIR LA FORMACION DE LA CAPA AMORFA DESEADA EN LAS BARRAS DE APOYO (30, 32) UNIDAS A LOS EXTREMOS DE LAS BARRAS.
