It was manufactured by heating the film and applying external pressure to press the tube and sheet against each other, and joining them together via a thermoplastic synthetic resin.
However, this manufacturing method has the problem of high costs because it is necessary to use a large amount of expensive thermoplastic synthetic resin film. Additionally, there was a problem in that the synthetic resin film adhered to unnecessary areas on the finished tube-on-sheet.

される。 First, an aluminum tube 1, an aluminum sheet 2, and a thermoplastic tube 3 made of nylon 12 are prepared. The wall thickness of the plastic tube 3 is 60 μm. Then, the aluminum tube 1 is covered with the plastic tube 3, and the plastic tube 3 is temporarily heated at 60° C. to shrink, so that the plastic tube 3 is brought into close contact with the outer peripheral surface of the aluminum tube 1. Next, the aluminum tube 3 is bent into a meandering shape, and then the cross-sectional shape of the aluminum tube 3 is deformed into a semicircle. Thereafter, the flat part of the aluminum tube 1 covered with the plastic tube 3 is brought into close contact with the aluminum sheet 2, and external pressure is applied by an upper die and a lower die (not shown) to press them together. Then, the plastic tube 3 is heated to 150°C and melted by passing it through a heating furnace while maintaining the pressurized state or by heating the lower mold, and the aluminum tube 1 and the aluminum sheet 2 are heated to 150°C and melted. and are joined via the tube 3. In this way, a tube-on-sheet is produced.

At least the part of the entire tube that covers the part of the metal tube that is to be joined to the metal sheet is heated and melted, and external pressure is applied to press the metal tube and metal sheet together, so that the two are bonded together through the thermoplastic tube. Since this method is characterized by joining two parts, the amount of thermoplastic used is reduced compared to conventional methods, and the cost is reduced. It also facilitates handling when the metal tube covered with the plastic tube and the metal sheet are brought into close contact. Additionally, no plastic will be deposited on unwanted areas of the finished tube-on-sheet.
