Description

B29D covers the manufacture of finished or semi-finished plastic articles through various forming and shaping processes applied to plastic materials or substances in a plastic state. This subclass encompasses diverse production techniques including molding, extrusion, thermoforming, casting, and lamination, applied to create specific end products such as containers, films, tubes, sheets, and composite structures. The classification focuses on the article-specific manufacturing processes rather than the general working methods, which are covered in the parent class B29C, or the machines and equipment used in production.
