Abstract

PURPOSE: To obtain the title member, e.g. a U-shaped one, free from joining or fused parts, by inserting a liner of such a shape as to connect the ends of plural parallel separation tubes into a mold, and by removing the liner after resin injection.
CONSTITUTION: The liner 24 in the mold 21 is attached to the holes 23 and 23 provided in the mold 22 for the inner surface of header, and a plastic is injected into the mold 21. The liner 24 is embedded in the plastic is removed to form the communicating part. The liner 24 is preferably composed of a low-melting alloy or a water-soluble solid. For example, the melting temperature of the liner of a low-melting alloy, e.g. Bi-Pb, is set at 120W125°C for the injection temperature of 210W 220°C, and the molded resin is kept at a temperature 5W10°C higher than the melting point of the liner, which is molten. The liner will not melt in injection due to its thermal conductivity.
