PROCEDIMIENTO PARA LA OBTENCION DE PIEZAS MOLDEADAS DE MATERIA SINTETICA EMBUTIDAS A PROFUNDIDAD.

摘要

To produce a thermoformed plastic moulding, cold-drawable sheet material is formed isostatically with the aid of a hydraulic fluid at a hydraulic fluid pressure of greater than 20 bar and at a working temperature below the softening point of the sheet material. The forming may be sudden. The sheet to be formed may be provided with a coating, for example a colour imprint. The thin-walled thermoformed part obtained may be provided with an injection-moulded backing of a further plastic and may be reinforced.
