Claims3
A method of manufacturing an air intake hose for a vehicle, the air intake hose having a blow molding portion formed in a hollow hose shape by blow molding and an injection molding portion formed in a hollow hose shape by injection molding, the method comprising:
- preparing materials of the blow and injection molding portions and an injection mold used for the injection molding;
- forming the blow molding portion;
- inserting a part of the blow molding portion into the injection mold through one end of the injection mold;
- injecting the material of the injection molding portion into the injection mold through the other end of the injection mold;
- and
- separating and removing the injection mold,
- wherein a plurality of protrusions are protruded from a coupled surface of the blow molding portion coupled with the material of the injection molding portion,
- wherein a width of the protrusions is gradually widened along a protruding direction, and
- wherein the material of the injection molding portion is injected between the plurality of the protrusions so as to obtain a strong coupling force.
