METHOD FOR MANUFACTURING SYNTHETIC RESIN HOLLOW OBJECT

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing synthetic resin hollow object capable of sufficiently performing integration by increasing adhesive length in a thickness direction by interposing an adhesive. SOLUTION: In joining a plurality of molded product split bodies 30 and 31 comprising a synthetic resin A, the molded product split bodies 30 and 31 are respectively arranged in molds 12 and 13. The joining surfaces 30a and 31a of the molded product split bodies 30 and 31 are brought into a close contact state under pressure by the approach movement of the mold 13 to be bonded and integrated through an interposed adhesive B. The joining surfaces 30a and 31a of the molded split bodies 30 and 31 can be bonded through the adhesive B, and the adhesive length in the thickness direction of the hollow object is increased by the inerposition of the adhesive B to manufacture the synthetic resin hollow object 33 wherein the molded split bodies 30 and 31 are integrated by sufficient adhesion. The molded split bodies 30 and 31 are positioned in the molds 12 and 13 to be held in shape and can be integrally bonded in an undeformed and accurately aligned state by the adhesive B to enable production with less defective products.
