Forming tool and method for producing a packaging

A forming tool for producing a packaging trough, the forming tool comprising:

• a female die part comprising a contact surface and a forming cavity having an opening, wherein the forming cavity of the female die part includes an insert, the insert being vertically movable from a first position in a displacement direction further into the forming cavity to a second position;
• a clamping unit, which is configured for clamping a residual area of a material sheet in position against the contact surface of the female die part when the pre-punched material sheet has been positioned on top of the female die part such that a sub-area of the material sheet at least partially covers the opening of the forming cavity of the female die part, wherein the sub-area of the material sheet is connected to a residual area of the material sheet through a plurality of retaining lugs;
• and
• a vacuum unit in fluid communication with the forming cavity and configured for sucking the sub-area of the material sheet onto the insert disposed at the first position using a vacuum.

A method for producing a packaging, comprising the following steps:

• positioning a material blank on top of a female die part of a forming tool such that the material blank at least partially covers an opening of a forming cavity of the female die part;
• sucking the material blank using a vacuum onto an insert of the forming cavity, the insert positioned at its first position, and the insert is vertically movable in the forming cavity of the female die part between the first position and a second position;
• and
• moving the insert from the first position in a displacement direction further into the forming cavity toward the second position to draw the material blank into the forming cavity for forming the material blank into a packaging trough.
