Abstract
PURPOSE: To prevent wrinkle formation even in case of deep-draw by vacuum forming the preheated sheetlike facing material in a female mold and then, vacuum forming it finally in a male mold as the desired shape.
CONSTITUTION: The sheetlike facing material is preheated, made soft and positioned between the female mold and the male mold, and the male mold 4 is lifted and stopped to the female mold 3. Next, the facing material is preformed by evacuating the female mold 3 and then, final vacuum forming is done by evacuating the male mold 4 of the desired deep-draw. To prevent cooling of the facing material during preforming, the inner surface of the female mold 3 is preferably covered by permeable thermal insulation material 7.
