Crack gap mold for producing a particle foam part together with an apparatus for producing a particle foam part

The invention relates to a crack-split moulding tool for producing a foam particle part, having two mould halves (2, 3). The mould halves (2, 3) are pivotably mounted relative to one another such that they can be arranged at a varying distance from each other in certain sections when being filled with foam particles and when pressing together, are moved together at a varying distance until in a closed position, due to a pivoting movement. As a result, it is possible to homogeneously compress areas of the moulding cavity (6) having a different thickness and to compress in a different manner, area having the same thickness.

Bonding process and system

A system and process for bonding involves a pocket made into one article is used to secure that article to another using a flowable, curable material (e.g., resin) which during saturation enters through a passageway and at least partially fills the void. When the article is cured, the article is bonded to another article to which resin has also been applied since the void (now containing cured material) is larger than the passageway.
