Description
B29 encompasses the mechanical processing, shaping, and manufacturing of plastic materials and other substances in a plastic state. This class covers machinery, methods, and apparatus for operations such as extrusion, injection molding, blow molding, thermoforming, and other forming techniques applied to thermoplastic and thermosetting materials. The scope extends to post-processing operations including trimming, joining, and finishing of plastic articles, as well as auxiliary equipment and control systems integral to plastic working processes. Adjacent classes address specific end-product manufacturing (e.g., B31 for paper and cardboard products) and material preparation stages handled elsewhere in section B.
