Resin-composite aluminum profiles, heat insulating aluminum profiles, and method and apparatus for production thereof

摘要

Disclosed are a resin-composite aluminum profile, especially a heat insulating aluminum profile (10) having a joined part of opposed lateral sheet members (2a, 2b) of an aluminum profile (1) formed with a resin material (5), a method for the production of the profile, and an apparatus, particularly a discharge treatment apparatus to be used for the production of the profile. A discharge treatment is effected on the surface of the portion of a coated aluminum profile destined for union with resin and a resin material is joined to the portion of discharge treatment. When the profile has a recess (3, 4) wished to be packed with resin, the discharge treatment is performed on the inner surface of the recess (3, 4) and the discharge treated recess is filled with the resin material (5). In the production of a heat insulating profile (10), after the resin material is filled in the discharge treated recess (3, 4), the portion (3a, 4a) of the profile forming the recess is cut.
