Abstract
A method for producing a plastic tank includes preparing a tank wall as a hot extrudate. A reinforcing sheet is then attached to at least one region of the outer layer of the hot extrudate. After introducing the attached reinforcing sheet and the hot extrudate into a shaping tool, the shaping tool performs shaping of the hot extrudate and the attached reinforcing sheet to form the tank wall, while simultaneously enhancing the attachment of the reinforcing sheet to the tank wall.
Claims16
A method for producing a plastic tank, the method comprising:
- preparing a tank wall as a hot extrudate, in which at least one outer layer of the hot extrudate is composed of a first material;
- attaching a reinforcing sheet, composed at least partially of the first material, to at least one region of the outer layer of the hot extrudate;
- introducing the attached reinforcing sheet and the hot extrudate into a shaping tool;
- shaping, via the shaping tool, the hot extrudate and the attached reinforcing sheet to form the tank wall, while simultaneously enhancing the attachment of the reinforcing sheet to the tank wall,
- wherein:
- attaching the reinforcing sheet comprises attaching the reinforcing sheet outside of the shaping tool via an extendable ram by pressing the extendable ram into the hot extrudate in a force-controlled or travel-controlled manner.
A method for producing a plastic tank, the method comprising:
- extruding, via an extruder, a hot extrudate having at least one outer layer composed of a first material;
- attaching, during a discharge of the hot extrudate from the extruder, a reinforcing sheet composed at least partially of the first material to at least one region of the outer layer;
- shaping, via a shaping tool, the hot extrudate and the attached reinforcing sheet to form the tank wall, while simultaneously enhancing the attachment of the reinforcing sheet to the tank wall by applying pressure in the shaping tool or by applying a vacuum in the shaping tool.
