CONNECTOR PIPE AND MANUFACTURE METHOD THEREOF

摘要

PURPOSE: A connection pipe manufacturing method is provided to increase the durability by preventing a crack since a reinforcing member and a body member are installed at the outside. CONSTITUTION: A connection pipe manufacturing method is as follows. A stopper(14), an inner mold, and a first outside mold are readied. A ceiling part(10) is formed between the inner mold and the first outside mold by injecting the elastomeric resin into the gap. A reinforcing member(20) is wound in the outer circumference of the ceiling part at the same time the first outside molds are removed. A second outside mold is united in the outer circumference of the wire-wound reinforcing member. The unsaturated polyester resin is injected and cured between the outer circumference of the ceiling part and a molding groove of the second outside mold.
