INFRARED PRE-FOAMING OVEN
Vaporless IR pre-foaming
The IR pre-foaming process patented by Fill offers the advantage of being able to further process the foam beads immediately, without any drying time. No elaborate infrastructure is required for generating steam. Thanks to the deep penetration of IR radiation into the granulate, the thermoplastic matrix softens evenly, resulting in improved mechanical properties, depending on the material.
No water residues
In contrast to the conventional process, where the granulate is added in portions in steam vessels, IR pre-foaming operates continuously. The raw granulate is metered on a conveyor belt and passes through special infrared heating fields for a few seconds. Then the foam beads pre-foamed to the desired density (material-dependent) are cooled down rapidly at room temperature. This means they retain almost 100% of their volume.
