METHOD AND APPARATUS FOR FORMING SEAL PORTION OF LAMINATED ALUMINUM TUBE |
摘要 |
A synthetic resin material of an end portion (5) which protrudes from a clamp jig (9) is heated and melted, and this protruding end portion is pressed and molded to a seal portion (8) inside a press molding space defining a gap into which the synthetic resin material intrudes between an aluminum foil layer (3c) and a mold surface, thereby setting the appearance of the seal portion (8) to a desired shape and completely covering the aluminum foil layer (3c). Further, the seal strength is increased by attaining a higher density by pressing. <IMAGE> |
