PURPOSE: The manufacturing cost is decreased vibration and noise of the fluid are absorbed when the fluid is circulated and vibration and noise can be reduced. CONSTITUTION: The manufacturing method of the synthetic resin neck jet discharge pipe in which the wood dust is contained. As to the method for molding the pipe by using resin. The synthetic resin wood dust mixing process(30) the wood dust(20) is and mixes added in the resin(10). The mixed resin wood dust mixture is fused with the synthetic resin wood dust mixing process. |
