PURPOSE:To form a faucet in which a rubber ring-coupling ring is buried by a method in which a rubber ring-coupling ring and a rubber core are closely attached to a tamping rod, and the end of a heated plastic pipe is inserted onto the rod and pressed by an external mold. CONSTITUTION:A rubber ring-coupling ring (a) is coupled and fixed to the tiered part of a tamping rod 1, and a rubber core (c) is attached to the adjacent land part 12. Then, the heated end of a plastic pipe P is inserted onto the rod 1. Where the burr of the rubber core (c) can be effectively prevented and can thus be easily kept at normal attitude because the pipe P can pass on the rubber core (c) after its diameter is expanded by the tapered part 13 of the rod 1. When pressing the end of the pipe P by an external mold 2 while it is soft, the rubber core (c) is compressed and the ring (a) is bitten deep into the faucet. The faucet is hardened by cooling, the external mold 2 is opened, the end of the pipe P is taken out of the rod 1, the rubber core is taken out, and the processing is completed. |
