る。In the method of manufacturing a spout according to this embodiment, the resin layer 4 is formed on the outer surface of the pipe 1 insert-held in the recess 3a of the mold 3 and a part of the outer surface of the water discharge portion 2, Since the surface of the resin layer 4 is plated, a spout having a degree of freedom in design, a sense of volume, and not giving a user a cheesy image can be manufactured at a lower cost than that of bulging or casting. Further, by forming the resin layer 4 on the outer surface of the pipe 1, it is possible to suppress the temperature rise of the surface of the spout when hot water is passed by the heat insulating action of the resin layer 4. By making the water discharge part 2 of the spout a separate part from the remaining part, the flexibility of the tip shape of the spout is increased and the design is improved. By making the water discharge part 2 of the spout from the filler-reinforced resin, it is possible to prevent the threads formed on the water discharge part 2 from being damaged by the load of the water purifier screwed onto the water discharge part 2 when the spout is used. Resin is highly resistant to chemicals such as detergent P
By using SU or PPS, even if a strong detergent is attached to the thread of the water discharger 2 in a state where a load is applied to the thread, the loss of the thread can be suppressed. PSU is A
Since the compatibility with BS is good, the water discharge part 2 is filled with filler-reinforced PS.
If it is made of U and the resin layer 4 is made of ABS or PC / ABS, no gap can be formed at the joint α between the resin layer 4 of the composite member 5 and the water discharge portion 2, and the joint α is masked during the plating process. It has the advantage of not being necessary. The water discharge part 2 is PPS
When the resin layer 4 is made of ABS and PC / ABS, the joint α between the resin layer 4 of the composite member 5 and the water discharge part 2 is formed.
It is desirable to mask the seam α during the plating process to prevent chemicals from flowing into the seam α because there is a possibility that a gap will be created in the seam. Pipe 1 is made of SUS steel,
The water discharge part 2 is made of PSU, the resin layer 4 is ABS, PC / A
Since the resin layer 4 is made of BS and is plated, there is a feeling of weight and there is no risk of the threads of the water discharger 2 being damaged by the load of the water purifier and the like, and the threads of the water discharger 2 are loaded. Even if a strong detergent adheres to the screw thread in the above state, the screw thread is not likely to be damaged, and it has a gloss, a beautiful color tone, and wear resistance, and plating is not easily peeled off, and a spout is obtained.
