Abstract
La presente invención se relaciona con un método para la producción de partes de moldeo de plástico, en particular reforzadas con fibras, alimentándose a una unidad de plastificación (3) de un solo tornillo unos cordones de fibras sinfín (10a, 10b, 10c, 10d, 10e, 10f) por medio de un dispositivo de freno de fibra (40) y/o fibras cortadas por medio de un dispositivo de dosificación 50) gravimétrico, así como una materia de plástico (34) por fundir por medio de un dispositivo de dosificación (30) volumétrico. La materia de plástico fundida y mezclada con materia de fibra es inyectada por medio de una carrera de inyección del tornillo de plastificación (5) a una herramienta de moldeo (2). Se calcula el caudal másico REAL de la materia de plástico del caudal másico volumétrico REAL de la materia de plástico y del caudal másico REAL de la materia de fibra. Se compara el caudal másico REAL de la materia de plástico con un caudal másico TEÓRICO de la materia de plástico y se ajusta eventualmente el número de revoluciones por minuto nd del accionamiento rotativo (33) del órgano de dosificación (32) del dispositivo de dosificación (30).
