Abstract

RESULTA ATRACTIVO PRODUCIR PEQUEÑOS OBJETOS DE MADERA, POR EJEMPLO, CABEZAS DE PIPA O ASAS DE MUEBLES, MEDIANTE UN PROCESO DE MOLDEO BASADO EN UNA SUSPENSION ACUOSA DE POLVO DE MADERA, PERO PORQUE LAS TENTATIVAS REALIZADAS ANTERIORMENTE Y PORQUE EL TIEMPO DE PROCESAMIENTO HA SIDO TAN LARGO, NO HA RESULTADO ECONOMICO PRODUCIR ESTOS OBJETOS CON LA ALTA CALIDAD REQUERIDA MEDIANTE ESTA TECNICA; UNA COSA IMPORTANTE ES QUE LOS OBJETOS MOLDEADOS DEBERIAN SER SECADOS CON UN MUY BAJO CONTENIDO DE AGUA. CON ESTA INVENCION, ES OBTENIDO UN PERIODO DE TIEMPO MUY CORTO, MEDIANTE LA UTILIZACION DE PARTES MOLDEADAS POR INYECCION (32) EN LAS CUALES, UNOS ELECTRODOS (34) ESTAN UBICADOS PARA SUJETAR LAS CAVIDADES DE MOLDEO (8), EN UN CAMPO DE CALENTAMIENTO HF QUE PROPORCIONA UN RAPIDO SECADO DE UN AGENTE LIGADOR, FIJADO MEDIANTE EL CALOR, EN LA MASA ACUOSA DE POLVO DE MADERA Y UNA RAPIDA EXTRACCION DE LA MAYOR PARTE DEL AGUA. LAS CAVIDADES DE MOLDEO (8) TIENEN CANALES DE ESCAPE (24, 26) PARA EL VAPOR Y MECANISMOS (6) PARA SUJETAR LAS PARTES MOLDEADAS (2 Y 4); AMBOS ESTAN DESIGNADOS PARA SER CAPACES DE SER EFECTIVOS A MUY ALTAS PRESIONES DEL VAPOR EXISTENTE DENTRO DE LAS CAVIDADES DE MOLDEO.
