Method and device for processing particle foam material to produce a molded particle foam part

Device for processing particle foam material for producing a particle foam molding, the device comprising:

• a first mold element and a second mold element, wherein the first and the second mold element are configured, in particular by at least one movement relative to one another, to define a mold cavity, wherein
• the first mold element comprises at least one opening, via which a process fluid flow can flow into the mold cavity via the first mold element, and
• the second mold element comprises at least one opening via which a process fluid flow can flow out of the mold cavity and into the second mold element, and comprises at least one opening via which a process fluid flow can flow out of the second mold element;
• a process fluid actuator device, which is configured for controlling or regulating the operation of one or more closure devices which can be or are assigned to the respective mold elements,
• is configured for generating a first process fluid flow which flows through the mold cavity, wherein the first process fluid flow flows into the mold cavity via at least one opening of the first mold element, and flows out of the mold cavity via at least one opening of the second mold element;
• and
• is configured for generating a second process fluid flow that flows through the second mold element, wherein the second process fluid flow flows into the second mold element via at least one opening of the second mold element and flows out of the second mold element via at least one opening of the second mold element, and
• is configured for setting at least one flow parameter that influences the flow properties of at least one process fluid flow, in particular in such a way that the first and the second process fluid flow differ in at least one flow parameter that influences the flow properties.
