Classification Context

Section:: PERFORMING OPERATIONS; TRANSPORTING
Class:: WORKING OF PLASTICS; WORKING OF SUBSTANCES IN A PLASTIC STATE IN GENERAL
Subclass:: SHAPING OR JOINING OF PLASTICS; SHAPING OF MATERIAL IN A PLASTIC STATE, NOT OTHERWISE PROVIDED FOR; AFTER-TREATMENT OF THE SHAPED PRODUCTS, e.g. REPAIRING

Description

B29C encompasses mechanical and thermal processes for forming plastic materials into finished shapes and joining plastic components together. This subclass covers injection molding, extrusion, blow molding, thermoforming, and other primary shaping techniques applied to thermoplastics, thermosets, and elastomers. It also includes post-molding operations such as trimming, annealing, welding, and repair of plastic products, as well as shaping of materials in a plastic or semi-solid state not classified elsewhere in Section B29. The subclass excludes processes specific to natural rubber or leather working (B29D) and upstream polymer synthesis or material preparation.
