Abstract (en)

[origin: WO2022223257A1] The invention relates to a method for filling a molding tool cavity (2.3) of a molding tool (2) for producing a molded particle foam part with particle foam material, comprising the steps of: - providing particle foam material that is to be processed in a molding tool cavity (2.3) of a molding tool (2) for producing a molded particle foam part by means of at least one filling container device (3), wherein a first pressure level prevails in the filling container device (3); - providing a molding tool cavity (2.3) that is to be filled with the particle foam material that is to be processed for producing at least one molded particle foam part, wherein a second pressure level prevails in the molding tool cavity (2.3); - filling the molding tool cavity (2.3) with particle foam material from the filling container device (3), wherein during the filling of the molding tool cavity (2.3) a difference between the first pressure level and the second pressure level is varied in a targeted manner by at least one measure for varying the difference between the first pressure level and the second pressure level.
