Method and apparatus for producing moulded parts from curable plastic material
Abstract
The invention relates to a method for producing a relatively thin-walled and large-area molded part made of thermosetting, in particular laminated material, for example plastic, in which the material in a closed, at least one stretchable film (4,6) and a positive and / or Inserted negative mold (1) limited mold space (8) and is distributed in the same by vacuum and / or pressure uniformly over the mold surface. In order to provide a method in which it is ensured even at very low wall thicknesses that the material is well and evenly, but especially in the time available, distributed over the molding surface, so that in particular inserted fiber mats (5) are imbued properly, is in a provided with distributed grooves (3) positive and / or negative form at the same form-fitting film by pressure and / or vacuum at least partially drawn into the grooves and flow channels (7) are formed, the material is on the flow channels below Pressure and / or vacuum evenly filled in the mold space and distributed over the mold surface (2) and at the end of the distribution orShaping process, the retracted in the grooves carrier sheet is moved back by pressure and / or vacuum in the plane of the forming surface.
