摘要： The invention comprises a method and apparatus wherein an insert, preferably made of plastic and preferably allowing a melt-on bonding with the tubes and whose floor has a traversing opening for each tube, is inserted into the first part of the injection mold (top mold or bottom mold) as a positioning element for the tubes in such a manner that the insert is at least partially locked or secured into the first part of the injection mold. A tube is then placed in each opening of the insert. A mandrel is then placed in each tube, whereupon the injection mold is locked in such a manner that, if necessary, the mandrels are locked into the second part of the injection mold (bottom mold or top mold). A molten thermoplastic material is then injected, via a sprue provided in the injection mold, into a cavity formed by the injection mold, the insert and the tube ends. The parts of the injection mold are separated after cooling of the thermoplastic material, which is maintained under pressure during the cooling at least initially. The mandrels are then removed and the tubes bonded to the insert by the thermoplastic material are removed from the first part of the injection mold and, if appropriate, the free ends of the tubes are also bonded to a second insert by means of the injection mold.

摘要： Process for permanently fastening the end or ends of at least one rod, made at least partially of a thermoplastic material and having at least one continuous cavity, in at least one opening of a support plate. The opening surrounds at least one rod, with each rod - in order to be fastened - positioned in its designated opening in the support plate. Each rod cavity exhibits a hydraulic diameter which corresponds to at least 10% of the minimum outside cross-sectional dimension of the rod, and the rod walls may exhibit pores which take up a maximum of 20% of the wall volume. The rods are positioned with the support plate in such a manner that the ends are essentially arranged vertically upward and the support plate essentially horizontally, and, subsequently, sufficient heat is applied to the rod ends from above, so that the rod ends will soften at least to some extent and the outside walls of the rod ends will expand to such an extent that they touch the wall surfaces of the support plate openings and adhere or fuse to thereto. Also disclosed is a heat exchanger which may be formed by this process.
